Wavelength Division Multiplexers
Video Filter WDMs for TV Signal Transmission
3 Ports FWDM
(1310/1490/1550nm)
Description
Micro-Optical WDM utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provides low insertion loss, high channel isolation, low-temperature sensitivity, and epoxy free optical path.
With high reliability in a wide temperature range, it is
suitable for a wide range of applications including Passive Optical
Network (PON), Fiber to the Home (FTTH), CATV, and ITV systems.
Features
* Video and IP Signal Mux/Demux
* Wide Operating Wavelength Range
* Low Insertion loss
* Ultra-Flat Wide Passband
* High Channel Isolation
* High stability and reliability
* Epoxy-free on Optical Path
* RoHS Compliant
Applications
* Testing Instruments
* Telecommunications
* FTTH Tri-Play System (Single-fiber 3-wavelength system)
