AVAGO HFBR-57E0LZ 1300nm Multi-Mode SFP and CRS212-1G-10S-1S+ IN not quite working

Hello,

I have been looking for a 1300nm multi-mode sfp module that is compatible with mikrotik routerboards (specifically CRS212… and RB953.. boards). I found an sfp module from AVAGO (HFBR-57E0LZ) that is 1300nm, multi-mode, 100Mb/s fast ethernet capable

.

The switch recognizes that there is an sfp present and can see some of the DDM information as well as whether or not there is an incoming signal. I have to force the speed and duplex to 100Mb/s full duplex and then I get a link ok status and see connectivity lights on both the switch and other device.

However, the switch does not pass any data to the other device. in the interface menu I can see tx activity but no rx activity on the port.
I have attached a supout.rif
supout.zip
I am wondering if anyone has experience with these or knows how to make them work, or if there is an alternative module that i can try. The fiber port on the other device is built-in and non-replaceable, hence the 100Mb/s fx port.

thanks

I’m no pro but possibly you need to swap tx and rx on one side of the optical link.

You may have tx going to tx, tx needs to go to rx

are you sure you can use 100mbps sfp on gigagit interface??
