Wavelength Division Multiplexer

详情

**0/***0nm and **0/***0nm WDM couplers are widely used in EDFA. They combine the pump power and optical signal into the Er-fiber. **0/***0nm WDM is used for EDFA C-band, and the **0/***0nm WDM in EDFA L-band. These couplers were built of Corning HI ***0 Flex or OFS BF*******2 fiber. ***0/***0nm WDM can be used to combine or split ***0nm and ***0nm optical signals, which double the fiber transmission capability and ensure bi-direction communication in the single fiber. It is widely used for fiber communication systems upgrading to expand the system capacity.
