Upgrade Port Passive 4 Channel Compact CWDM Module
4 Channel Compact CWDM Module Passive CCWDM with Upgrade port
GEZHI specialized in custom configured, reliable, CCWDM products based on customer requirements. Our 4 Channel Compact CWDM Module Passive CCWDM with Upgrade port is based on Free Space Optics & has better uniformity versus Thin-Film Filter (TFF) designs. GEZHI's High Isolation, Low Insertion Loss, low PDL Compact CWDM Module Passive CCWDM offer high quality parameters with 4 wavelength 1470nm, 1490nm, 1510nm, 1530nm and with a upgrade port for the future development and fiber extend.
It can replace CWDM Products are used in telecommunications, PON networks, corporate networks, cable TV and other fields. The lower insertion loss makes the CCWDM module have lower signal attenuation when used, thereby reducing the power requirements of the signal transmitter.

Unique Free-Space Technology
The 4 Channel Compact CWDM Module Passive CCWDM with Upgrade port adopts Free-Space technology, which uses light propagating in free space to wirelessly transmit data. Inside the device, adjacent signal channels are cascaded by parallel beam instead of the fiber. This saves a lot of space for package box, and the unique workmanship also helps CCWDM Mux Demux with low insertion loss.
