FAQs

Q: Is this module compatible with 1G Ethernet and 2G Fibre Channel?
A: Yes, it supports 1000BASE-X Ethernet and 1/2G Fibre Channel at the 1550 nm CWDM wavelength.

Q: What fiber and connector do I need?
A: Use OS2 single-mode fiber (9/125 µm) with an LC duplex connector.

Q: How far can this CWDM SFP reach?
A: Up to 80 km over suitable SMF when link budget conditions are met.

Q: Does it support digital diagnostics (DOM)?
A: Yes, it supports SFF-8472 DOM for monitoring temperature, TX/RX power, and voltage.

Q: Do I need a CWDM mux/demux to use this?
A: A CWDM mux/demux is required only if you plan to combine multiple wavelengths on the same fiber pair.

Q: Will it work in any SFP slot?
A: It requires an SFP port that supports 1000BASE-X/CWDM optics and the platform’s approved transceiver list.
