Standard WDM

Standard WDM is working at 1310/1550nm, its standard isolation is 18dB, its high isolation is 30dB,

and its ultra-high isolation is 40dB.

Pump WDM

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.

Filter WDM

It includes C+L band Filter WDM, C band supervisory channel WDM,

L band supervisory channel WDM, C band Red pass WDM, L band red pass WDM, 1310/1550nm/1625nm filter WDM
