LGX Box FWDM Filter 1310 1550 1650nm Wavelengths Low Insertion Loss for Optical Communication
Crafted for high-performance optical network upgrades, this LGX Box FWDM Filter integrates dual FWDM filters paired with spliced reference branches, enabling targeted bypass of 1650nm wavelengths. Leveraging premium Thin Film Filter (TFF) technology, it delivers stable, consistent operation even in harsh optical network conditions, making it a reliable choice for fiber optic transmission system enhancement.
FTTX Filter WDM Modules are widely deployed across EDFA systems, Raman amplifiers, WDM optical networks and professional fiber optic instrumentation. Engineered to integrate and split optical signals of distinct wavelengths across a broad spectrum, these modules dramatically boost single-fiber bandwidth, enabling high-efficiency bidirectional data transmission. They serve as a cornerstone component for optical network upgrades, infrastructure expansion and the rollout of full-featured new business services.

The Filter WDM system employs a Multiplexer at the transmitter to combine multiple wavelengths (each carrying different signals up to 10G bite-rate) and a demultiplexer at the receiver to separate them. With low insertion loss, minimal polarization dependence, and high isolation, this filter is widely used in CATV systems, FTTx and PON systems, fiber communication networks, and test instrumentation.
