Cisco GLC-LH-SM compatible ASF13-24-20-D 1000Base-LX SFP transceiver, 1310nm, 20KM I use it on Cisco 2960. It works fine for the first time, but it can’t work after I plug it out and test another transceiver. It said: HAS BAD CRC.

At November 2017 I ordered 1 piece of x540-T1 and x540-T2 for our QNAP Data Storage upgrade. Now I would like to order one X550-T1 for our new video editing PC. At the QNAP storage we installed X540-T2. One port is connected to a video editing machine wit
The QSFP+ BIDI transceivers were employed on Mellanox MLX-2700B (Cumulus IOS). There is no useful DOM information from the “ethtool-m” data.
