Product Description

1260- 1460 GHz PM CWDM Modules can be customized

Product Description

PM CWDM modules are polarization-maintaining optical fiber circulators and isolators that are used in Coarse Wavelength Division Multiplexing (CWDM) systems. CWDM is a low-cost technology that combines multiple signals at different wavelengths into a single fiber optic cable for transmission.

Features	Applications
High Return Loss	CATV system
High Stability & Reliability	DWDM System
High Return Loss& High lsolation	EPON and GPON network
Good channel-to-channel consistency
