CATV System
Broadband wavelength division system
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.
