This WDM coupler is used to combine or separate 1625nm channel with three triplex wavelength 1310nm, 1490nm and 1550nm. Using this device, 1625nm channel can be added into the existing triplex FTTH system. Each triplex channel has +/-30nm optical bandwidth, while 1625nm has +/-20nm optical bandwidth.
This WDM coupler is based on thin-film filter technology, that ensures low insertion loss, wide operating wavelength range, low PDL and high environment stability.
- Low insertion loss
- Low PDL
- High wavelength isolation
- High stability and reliability
- Optical fiber triplexer FTTH networks
- WDM systems
