Description Dense wavelength division multiplexer(DWDM) is based on the membrane filter technique and proprietary non-flux metal bonding micro-optics packaging design, within ITU wavelengths to achieve uplink and downlink. It provides ITU channel center wavelength, low insertion loss, high channel isolation, low power consumption, wide passband characteristics, no glue loop, excellent thermal stability and reliability and so on. In a telecommunications network system, it can be used for uplink or downlink optical signal. Features
Low Insertion Loss
Excellent Channel Isolation
High Channel Isolation
High Stability and reliability
Epoxy-free on Optical Path
Low Cost
Applications
WDM Channels Add/Drop Systems
WDM Networks & Systems
CATV Fiber Optical Links
Long Haul & Short-Distance Applications
Accessing LAN & WAN Network
