For extremely long fiber transport distances of greater than 80 km, fiber-optic dispersion compensation modules are often required. These are passive devices intended for signals in the 1550 nm range. Because of the insertion loss, it is often necessary to use these modules with an Erbium-Doped Fiber Amplifier (EDFA) before the signal enters the DCM. When used properly, this equipment can enable fiber-optic transport of signals beyond 200 km.
1 x 2 to 1 x 128 Fiber Optic Couplers
Fiber optic optical couplers for passive optical splitting and coupling
Wavelength Division Multiplexer WDM
Wavelength Division Multiplexer units for WDM, CWDM, or DWDM applications. We can also customize our equipment for use with these optics.
