IEEE 802.3u and IEEE 802.3z Compatibility

[fgasimzade]

Hello everyone!

Does anyone know if these 2 fiber optic SFPs are compatible with each other?

We have and old HP J4853A transceiver which is 802.3u and Cisco SFP LX Module which is 802.3z

Thank you!

Another follow up question

Will HP J4853A and Cisco SFP Module 100BASE-FX modules be compatible?

Thank you!

Hello

For your reference, when talking about fiber transceiver you want to check the following details:

- There exists two modes: Single mode, and multi-mode, you want to make sure both use the same mode.

- Wavelenght, there are 850nm, 950nm, 1310nm.... You need to make sure it matches.

- No all switches/routers support all types of modules, so check the following compatibility matrix to make sure hardware and tranceiver are compatible.
