Sharp Vision FWDM (Filter Wavelength Division Multiplexer) couplers are passive optical devices used to combine or separate different wavelengths (typically 1310/1490/1550nm) in fiber optic networks, crucial for FTTH and CATV applications. They enable bidirectional communication on a single fiber, feature low insertion loss, and are built to Telcordia standards for stability.
Key Aspects of Sharp Vision FWDM Couplers:
- Technology: Uses Thin Film Filter (TFF) technology, providing high isolation between channels.
- Application: Ideal for WDM networks, CATV systems, and fiber optic instruments.
-
Features:
- Wavelengths: Supports 1310/1490/1550nm for multiplexing/de-multiplexing.
- Performance: Low insertion loss and minimal PDL (Polarization Dependent Loss).
- Reliability: Designed for high temperature stability.
- Product Types: Includes standard FBT (Fused Biconical Taper) couplers and 3-channel MUX options.
