WDM Coupler 1310/1550nm - Fused Fiber
WDM Coupler-1310/1550nm fiber coupler enables the multiplexing and de-multiplexing of two wavelength windows - 1310nm and 1550nm. It can be used to double the fiber transmission capacity or enable the bi-directional communication using one single fiber. This optical fiber coupler has high optical isolation, ultra-low insertion loss, excellent temperature stability and low polarization dependent loss. Different package and connector options are available.
Features:
Low insertion loss (no more than 0.3dB for standard grade products)
Low PDL (no more than 0.15dB for standard grade products)
High wavelength isolation
High stability and reliability
Applications:
WDM systems, CATV networks
Bi-directional optical fiber communication systems
WDM Coupler 980/1550nm - Fused Fiber
WDM (wavelength division multiplexing) pump coupler multiplexes pump laser powers at 980nm and optical signals at 1550 or 1590nm into Erbium doped fiber in an optical amplifier. Usually 980/1550nm WDM couplers are used in C band EDFAs, while 980/1590nm WDM couplers are used in L band EDFAs. With high stability and reliability, this product is an ideal component to be used in optical amplifiers prototyping, testing and manufacturing.
Features:
Low insertion loss
Low PDL
High wavelength isolation
High stability and reliability
Applications:
C or L band Erbium doped fiber amplifiers
Pump laser power rejection
