FAQ About 25G CWDM Optical Transceiver

What is a 25G CWDM optical transceiver used for?

A 25G CWDM optical transceiver is commonly used in data centers, metro networks, and telecom environments to enable high-speed, long-distance transmission over single-mode fiber using coarse wavelength division multiplexing (CWDM) technology.

How many CWDM channels are supported by 25G SFP28 transceivers?

25G SFP28 CWDM modules typically support 8 channels ranging from 1271 nm to 1371 nm, allowing efficient multiplexing and fiber resource savings.

Is the 25G CWDM transceiver compatible with existing SFP+ ports?

Yes, 25G CWDM modules are backward compatible with SFP+ ports, but will operate at 10G speeds. Full 25G performance requires an SFP28-compatible port.
