Fiber optic connection of an Internet box using a media converter and Ethernet cable

    • Fiber optic connection of an Internet box in the event of a greater distance between the OTO socket and router using a media converter and Ethernet cable

    In the thread “Fiber optic connection in a closet” some posts deal with the Swisscom proposal for adapted network cabling with fiber optic connection and media converter. Different observations were reported: there were both successful and unsuccessful attempts. No cause for the observed behavior could be found. This post summarizes some previous posts in the thread and also contains my own experiences. It may be of interest to people who also want to use this solution. The conclusion is mentioned at the very end of the post.

    Swisscom proposal (fiber optic connection):

    Swisscom-Proposition.jpg

    Note: In the diagram shown, the network sockets in the “living room” are labeled incorrectly (LAN1 and LAN2 swapped). An analog error is present with “Sleep” and LAN7/LAN8. To implement this proposal, two additional components are required:
    1) TP-Link MC220L - Gigabit Ethernet media converter
    2) Skylane SGT00P10DR00 SFP Copper (or Cisco Transceiver Module SFP 1000BASE-T)

    The TP-Link MC220L media converter poses no problem: it is clearly identified and available from several sources in Switzerland. The second component (the 1000Base-T SPF module) is not so easy. The product “Skylane SGT00P10DR00 SFP Copper” seems to have been identified with sufficient precision, but it is probably not easily available in Switzerland. Several Cisco products for which the name “Cisco Transceiver Module SFP 1000BASE-T” could apply are available in Switzerland. But not everyone seems to be suitable. This is the reason for this slightly longer post.

    A) Summary of some previous posts in the thread mentioned above:

    @Tux0ne mentions in his Post as a possible source of supply for the 1000Base-T SPF module :
    https://www.digitec.ch/de/s1/product/cisco-mgbt1-ethernet-1000base-t-mini-gbic-sfp-transceiver-netzwerk-zubehoer-243049
    According to the link provided, this is the product “Cisco MGBT1 Ethernet 1000Base-T Mini-GBIC SFP (Transceiver)”.

    Note: I assume that all users who posted in the specified thread about using a Cisco 1000Base-T SFP module sourced from Digitec are using the “MGBT1” module.

    @Rattenjunge mentioned in his post as a source of supply for the 1000Base-T SPF module:

    http://www.steg-electronics.ch/de/article/product-14184709.aspx

    According to the link provided, this is the product “Cisco Transceiver Module SFP 1000BASE-T, Cisco GLC-T, Copper Gigabit Module RJ-45”. Rat boy mentioned in the Post: “… I have the whole thing now Used, no problems so far…”
    Summary: The Cisco SFP module “GLC-T” has been successfully deployed. It is not clear from the thread whether an IB Standard, IB Plus or IB 2 is in use.

    @Studermarc009 mentioned in his Post: "I have exactly the same thing:
    - TP-Link MC220L - Gigabit Ethernet media converter
    - Cisco Transceiver Module SFP 1000BASE-T
    It really drives me crazy that it doesn’t work. I don’t understand why."

    Studermarc009 mentions in his Post: “And I have the components on Digitec.ch ordered.”

    Studermarc009 mentions in his Post: ""The problem is when I use the converter plug between the IB2 and the glass connector:
    Swisscom socket with glass -> converter with the glass SFP from Swisscom -> ethernet cable to the IB2 in the glass port with the Ethernet SFP. And then suddenly there’s no internet anymore."
    Summary: Studermarc009 uses the IB 2 and the Cisco 1000BASE-T SFP from Digitec. I assume that this is the “MGBT1” (see post by Tux0ne). The connection to the Swisscom network does not work."

    @fami18 mentioned in his Post: “I have the same problem as Marc, that The IB2 doesn’t work. I also have Cisco and TP from Digitec… but now when I connect my old IB boxa it doesn’t work wonderful.”

    Summary: fami18 uses a Cisco 1000BASE-T SFP from Digitec. I assume that this is the “MGBT1” (see post by Tux0ne). The connection to the Swisscom network does not work with the IB 2. However, the connection to the Swisscom network seems to work if a different Internet box model is used. It is not clear whether this is an IB Standard or an IB Plus.

    @user109 mentioned in his Post: “I’ll be able to test it in a few days. SFP Ethernet has been ordered.”

    According to the link provided, this is the product “Skylane SGT00P10DR00–RJ45 transceiver copper 10/100/1000Base-mini-gibic SFP”
    Note: The thread mentioned has not yet mentioned whether the mentioned test was carried out.

    B) Own tests with the Internet-Box 2, the media converter MC220L and the two Cisco 1000Base-T SPF modules “MGBT1” and “GLC-T”

    Components used in the test:

    Photo of the three SFP modules used:

    SFP-Module.jpg

    General procedure:

    1) Insert the 1000Base-BX SFP into the SFP slot of the MC220L
    2) Connection between the OTO socket and the 1000Base-BX SFP (in the MC220L) with fiber optic cable (LC/APC-LC)
    3) Insert the 1000Base-T SFP into the SFP slot of the IB
    4) Connection between the 1000Base-T Anschluss of the MC220L and the RJ45-Anschluss of the 1000Base-T SFP (in the IB) with Gigabit Ethernet cable
    5) Switch on the MC220L (connect to power with power supply, LED “PWR” lights up constantly green, LED “LINK FX” lights up constantly green)
    6) Turn on the IB

    1) Test with the Cisco SFP module_ “MGBT1”:
    A little more than 10 seconds after switching on the IB, the LED of the MC220L “LINK TP” begins to glow constantly green, after a little less than 30 seconds after switching on the IB, the LED “LINK TP” turns dark (a little before that, the LED flashes “ RX TP” briefly green), the LED of the IB flashes slowly red. The IB is not connected to the Swisscom network. Even after a longer period of time (e.g. 15 minutes) no further change can be noticed.

    Summary: The test with the Cisco SFP module “MGBT1” and the IB 2 was not successful.

    Screenshot “Internet Box/Diagnosis/Internet Diagnosis”:

    IB2_Status_MGBT1.jpg

    2) Test with the Cisco SFP module “GLC-T”
    A few seconds after switching on the IB, the LED of the MC220L “LINK TP” lights up green. The “LINK TP” LED briefly goes dark and then lights up constantly green again. The “RX TP” LED starts flashing green. Almost 50 seconds after switching on the IB, the LED of the IB lights up constantly white. The IB is connected to the Swisscom network. Normally the IB is also connected to the Internet. Registration may be necessary (http://www.swisscom.ch/registration).

    Summary: The test with the Cisco SFP module “GLC-T” and the IB 2 was successful. Screenshot “Internet Box/Diagnosis/Internet Diagnosis”:

    IB2_Status_GLC-T.jpg

    C) Conclusion:

    I assume that the Cisco 1000Base-T SFP module “MGBT1” cannot be used successfully with an IB 2 (at least for now, perhaps later with a different IB firmware version). All such attempts mentioned so far in the thread and the test described in this post were unsuccessful. However, the IB 2 was successfully connected to the Swisscom network in combination with the Cisco 1000Base-T SFP module “GLC-T”. However, there is also an indication that the SFP module “MGBT1” can perhaps be used successfully with other Internet boxes (IB Plus, IB Standard). The question naturally arises as to the cause of the different behavior of the two Cisco SFP modules “MGBT1” and “GLC-T”. I have to pass here. Maybe someone in the community has an idea.

    The StarTech SFP module (available e.g. from Microspot) is also compatible and identical to the Cisco module.

    [https://www.microspot.ch/msp/de/netzwerk/netzwerkadapter-extern/startech.com-gigabit-rj45-kupfer-sfp-transceiver-m-0001230443] (https://www.microspot.ch/msp/de/netzwerk/netzwerkadapter-extern/startech.com-gigabit-rj45-kupfer-sfp-transceiver-m-0001230443)

    Another small note, for everyone who - like me - already had a media converter from Swisscom, e.g. B. got a Business Internet Light:

    The media converter is preconfigured and VLANs 10 and 11 are untagged. It is “managed”, i.e. it has an IP over which it can be administered (by default: 192.168.0.1), the admin password is empty by default (if Firefox doesn’t work, use Internet Explorer).

    It is important that on the one hand the VLAN configuration must be deactivated in order to connect directly to the SFP port of the IB(2) AND on the other hand the NVRAM config must be saved explicitly using “Save/Restore Config”, otherwise the configuration will be discarded if power is lost.

    Hello everyone,

    Can I also use the switch via LAN directly from the media converter to the Internet box plus and then to the peripherals/Wi-Fi?

    Thank you very much,

    willy

    @willi9999 You need the media converter and a LAN-Gbic (SFP) for the router.

    Fiber->SFP -> Media Converter -> LAN -> LAN-SFP -> Router.

    The cable cannot be connected to the switch of the IBP, it must always be connected to the SFP-Anschluss of the IBP.

    See my post: [https://community.swisscom.ch/t5/Internet/Glas Fiber Connection-in-a-Wandschrank/td-p/452540/page/9](https://community.swisscom.ch/t5 /Internet/Fiber optic connection in a closet/td-p/452540/page/9)

    Hello User109,

    Thanks.

    SFP -> I get from Swisscom (if I read correctly) when I switch to fiber

    LAN-SFP -> is already in the IB+ (I currently have DSL)

    So I only need the media converter.

    Is that correct?

    Thank you very much

    @willi9999 You cannot use the DSL-Anschluss (RJ45 port) for this. You still have to buy a LAN (Ethernet) SFP and plug it into the SFP port of the IB.

    If you have a G-Fast SFP, unfortunately you cannot use it because it is a modem module and not an Ethernet module.

    Hello everyone

    I’m facing this exact problem.

    At the moment the standard Internet box is connected to the fiber optic socket in the closet.

    Now I found this guide and I still have questions. Are there any new findings about the components? Or does the same information still apply? I will definitely purchase the Cisco 1000Base-T SFP module “GLC-T” unless there is any news about it.

    Since a landline number will still be subscribed to in the foreseeable future, the question is whether telephony will also work normally? Will a Swisscom HD Phone function normally via IBS even after this installation, or does it still need adjustments?

    Thank you for your help.

    @fmueller

    Just a reminder: Converting from fiber optic to Ethernet and then back to fiber optic is certainly an option, but if you want to overcome a distance of <20 meters, for example, there are also pre-assembled fiber optic connection cables (long connection cable for direct connection OTO- Socket to fiber optic port of the Internet box) for approx. 30 CHF (20 meters of fiber optic cable including the required 2 plugs).

    So if you have a pipe from the control cabinet with the OTO socket to the desired router location that still has enough space, you can also pull in a “long” fiber optic connection cable directly.

    With this solution you wouldn’t need any additional adapters and conversions at all.

    Thanks for your answers.

    Since my daughter’s apartment has just been renovated and LAN ports have been installed in the individual rooms, I think I should do it this way. In terms of floor plan, it’s also easier than pulling a fiber optic cable.

    Hence the question of whether you should still use the same components and the question about telephony.

    Hopefully you have 2 LAN ports at the new router location…. 1x to return the LAN signal to the patch panel

    Unfortunately no.

    But where the IBS goes, it can then connect the TV box to the router normally. Just like the game box.

    The other thing would be great, then you could also distribute the LAN signal to the other rooms. Although this is not actually needed.

    It’s much better if you can take the router out of this control box. The location at the new location is central for WiFi. Maybe an IB2 will be added.

    @“x”#916we have similar distribution box problems - did your installation work? I followed the very helpful summary from @rokx (Thanks!) and also bought a Cisco GLC-T 1000base-T SFP slot with a TP MC220L V4 avoidance converter, which also seems to recognize the fiber optic signal as hoped . Unfortunately, the cable connection using the Ethernet SFB slot with my IBS apparently doesn’t work - when the IBS boots, the TP Link starts flashing diligently, but then stops, something like @rokx above under Test1 Cisco SFP module “MGBT1” and IB2 described. What kind of box did you use? Thanks for a tip. It would be stupid to buy this IB2 and then it wouldn’t work again. By the way, my GLC-T is model 30-14-10-04, made in the USA.

    NB: Wouldn’t it be great if you could bury the IBS, which unlike the IB2 fits into most distribution boxes, and then offer DECT and WLAN outside via Ethernet using this WLAN box? Will the IBS firmware upgrade that was announced for summer make this possible? Then you could save yourself this stuff.

    Yes, of course, but unfortunately no.

    WiFi no problem. There hasn’t been enough study on DECT yet…

    The WLAN-Box (unfortunately) cannot use DECT.

    However, the DECT range is significantly higher than WLAN, so it may well be that even if the IBS is in the electrical box, the telephones also work further away… (try it out)
    The electrical box should not have a metal door. Plastic or no door

    Truly worth a try (after a long time) 😉

    Thanks @POGO 1104 and @Herby for feedback, seems to me to be a lost opportunity for this distribution box problem, this WLAN box, but good. I actually have everything together to implement this in and out of the distribution box. Instead of the bulky Swisscom switch, a small managed switch GS105e 200pes from Netgear is already humming and it works perfectly (and also fits into the distribution box). No problems with Swisscom TV2.0, at least so far. Now I just have to be able to connect the MC220L to some IB, and that’s where I’m at. Maybe this would all work with the IB2, because I’m now forced to leave the router outside. Unfortunately, leaving the door open is not an option, I’m afraid I’ll get in trouble with the family.
