WDM can be used for dual-window multiplexing and de-multiplexing. It can double the
optical transmission capacity and realize bi-directional communication in a single
optical fiber. Thus it can be used to multiplex or de-multiplex digital and
analog signal without additional optical fiber. Designed and manufactured according
to strict quality controlling standard, it has low insertion loss and high
environment stability.
Specifications
  • SM WDM 980/1550, 980/1590
    • The fiber amplifier WDM enables the combination of pump and signal in C-band 980nm pumped Erbium Doped fiber Amplifiers (EDFA). The uniquely low insertion loss of this component, across the whole C-band, enables manufacturers to achieve the lowest noise figure in their amplifiers. Similarly low loss in the 980nm window maximizes the pump power reaching the Erbium fiber. Applications include EDFAs for dense WDM systems, pre and post amplifiers and optical noise sources. 980/1550nm WDMs are manufactured using optical fiber with numerical aperture intermediate between that of signal and gain fiber to enable mode-field matching and bend-insensitive single mode operation at both wavelengths.
  • SC-1脕, N脕
    • All of the fused components are manufactured as star devices with continuous fibers. Tree couplers are made by termination the unused ports for minimal back reflection.

  • PIC 1X2,2X2
    • The tap-couplers use a proprietary coating process to selective reflects a small amount of light from the input. As a tap monitor, they possess low PDL and a flat wavelength response across the erbium gain spectrum. They are specifically designed to be used in conjunction with erbium-doped amplifiers and other polarization sensitive applications. As the equipment there is three types, PIC Tap-couplers, PWIC Tap-couplers, PWFC Tap-couplers. For details please refer to them.
  • SC-1?, 2?
    •  Single mode couplers are used to split light with minimal loss from one to tow fibers or to combine light from tow fibers into one fiber. These components are excellent for duplex transmission on a single fiber, CATV systems or within fiber optic test sets.
