CWDM Bandpass Skip Filter

Description:
Fiberdyne Labs offers a wide variety of banded Singlemode CWDM skip filters which are typically used in add/drop multiplexing applications. The banded skip filters reduce insertion loss, and simplify upgrades, by passing predefined CWDM channel bands. The CWDM skip filters are available as single filters, with or without connectors, packaged in LGX Modules, packaged in FiberPassHD cassettes, or dual packaged in our innovative Fiberdyne Passive Optical Patchcord (FPOP) cable assemblies.

Features:
- Singlemode Fiber
- High Isolation
- Low Insertion Loss
- Complies with RoHS
- Complies with Telcordia GR-1209, GR-1221
- Convenient selection of packaging
- Most connector styles available

Applications:
- Local Area Networks
- FTTH Networks
- CATV
