TSW202: 100Mbps SFP Modules

[JockScotland]

Any update on this previous post please?

Hi Team

We’re looking at using TSW202 in an industrial environment, the same this post:

Hello, Does the TSW202 support 100Mbit SFP only fiber modules. I don’t get it to work right now, in some other brands of switches you should set the port speed fix at 100Mbit to get the 100Mbit Only SFP to work. But there is no speed setting available for the TSW202. We are investigating this option for a project. Best Regards, Johan

TSW202 is a really attractive option, as its L3 and managed, at a really good price point.

The site is pretty big and uses 155mbps, 1310uM Multimode (on OM1 fibre, which is probably not relevant, but it only supports lower data rates at longer distances), to give a maximum link range of 2km.

We have tried some StarTech SFP modules which use the standard above but we cant get the TSW202 to link, or at least, they do occasionally link to other devices using these modules but are really erratic. Using other modules to link to more modern switches at 1Gbps works fine.

Placing the same modules in an older desktop ZyXel switch that supports 100Mbps SFP connections works flawlessly with the same module when linking to other unmanaged switches on the network.

The TSW202 is an industrial switch and as such it really needs the ability to connect to other industrial switches at 100mbps, which is a fairly widely used standard. Has anyone found a solution to this?

Thanks

Ah i just posted few hours the same now i see your topic, which i could reply for the same. I used configurable SFP Modules, it has nothing todo with the brand. It is an implemention thing.

I have also a strange behavior, when I put the 155 Mbit/s module inside SFP1, nothing is happening, tjhe other site is not recognizing any LWL Signal. When i put the transceiver modul in SFP2, the other site recognize a “Link” (LED indicator is green and ON), but not teltonika TSW2X2
