FTTH FTTx 1x2 1310nm 1490nm 1550nm 1625nm Optical Fiber WDM Filter FWDM

?

Description

Filter WDM module is based on thin-film filters technology and epoxy-free optical patch. They are widely used in CATV, EDFA, Raman amplifiers, WDM networks and optical instrumentation.

The device combines or separates light at different wavelengths in a wide wavelength range. It can expand the capacity of a single fiber to achieve bidirectional communication, so that it widely used for optical network upgrade and expansion, or introduce new comprehensive business etc.

Seifree provides wavelength division multiplexing (WDM) filter devices that are customized to the particular wavelength bands for your special applications.
