The Filter WDM system utilizes a Multiplexer at the transmitter to combine multiple wavelengths (each carrying signals up to 10G) and a demultiplexer at the receiver to separate them. With low insertion loss, minimal polarization dependence, and high isolation, it's ideal for CATV systems, FTTx and PON networks, fiber communications, and test instrumentation.
Custom configurations available with various package types (Steel, ABS Box), connector options (LC, SC, FC, UPC, APC), wavelength ranges, fiber types, and port specifications.
1) All specifications are based on devices without connectors and guaranteed over wavelength, polarization, and temperature ranges.
2) PMD and chromatic dispersion values are guaranteed by design.
3) Specifications subject to change without notice.
