The 1530 - 1580 nm 100/200G Add/Drop Module is used to drop and add one or more ITU wavelength channels with 100 GHz or 200 GHz spacing in DWDM systems.
The 1550 nm Polarization Maintaining Isolator WDM Hybrid is ideal for fiber amplifier application to combine signal and pump wavelengths with very stable 1550 nm signal isolation.
