4 Channel Optical Add Drop Multiplexer Single fiber 1470/1490/1510/1530nm
GEZHI's Optical Add Drop Multiplexer is single fiber with four channel of CWDM wavelength 1470nm 1490nm 1510nm and 1530nm. The optical Add & Drop multiplexer combines wavelength channels onto an optical transmission fiber. Gezhi's 4CH CWDM OADMs are used in WDM systems for multiplexing or demultiplexing and routing fiber optic signals, selectively adding and dropping individual or sets of wavelength channels from a CWDM stream.
The CWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) configurations supporting up to four wavelengths. Each GEZHI's CWDM OADM uses wavelengths from 1270nm to 1610nm or 1271 to 1611nm with 20nm spacing.
