Description The Cisco CWDM-SFP10G-1390-20 compatible 10GBASE-CW20 module provides robust 10Gb/s performance over a 20km span using single-mode fiber (SMF). Operating on the 1390nm CWDM wavelength with a duplex LC connector, it offers an efficient, fiber-saving solution for intermediate-reach Cisco networking. This module ensures stable signal integrity over fiber-constrained spans.
