WDM Coupler Singlemode 1310/1550nm

WDM - Wavelength Division Multiplexing, a technology that simultaneously transmits multiple channels (wavelength) through a single optical fiber. Three different kinds of wavelength coupling combination are available for CATV systems, EDFA as well as Hi speed optical transmission systems.

Fiber-MART provides WDM for EDFA, WDM for Communication System, Custom-made WDM, 1480/1550nm WDM & 1480/1590nm WDM, 980/1550nm WDM & 980/1590nm WDM, 1310/1550nm WDM, 1310/1550nm HWDM & 1310/1550nm SWDM.
