Product details
Foxcom Coarse Wavelength-Division Multiplexer (CWDM) multiplexer and demultiplexer combine up to eight optical channels onto a single fiber and then separate them at the far end. The units follow the ITU CWDM grid with 20 nm spacing from 1471 nm to 1611 nm, enabling multiple L-Band and 70/140 IF signals to share one fiber over distances up to 50 km in a compact 1U, 19-inch form factor. Foxcom CWDM Multiplexer & Demultiplexer let multiple services share a single fiber under the ITU CWDM standard. Up to eight channels are combined with 20 nm spacing across the 1471–1611 nm band, then separated at the far end for distribution to individual paths. Thin film filters keep insertion loss low and channel isolation high, so L-Band and 70/140 IF signals can run in parallel without crosstalk. The units are protocol transparent and drop into RF over Fiber networks to reduce new fiber builds or lease costs. Available in a compact 1U, 19 inch rackmount enclosure, they support link budgets planned for extended runs, with deployments commonly reaching up to 50 km.
