Single Mode 1×2 and 2×2 Module FBT Coupler
Fiber optic accessories, such as adapters, connectors, patch cords, pigtails, attenuators and splitters, are vital to fiber optic network.
Fiber Optic FBT Couplers adopt FBT (Fused Biconical Tapered) technology, and are used for optical signal coupling of fiber transmission and optical power re-allocation. FBT coupler is the most cost-effective and easy connective device in optical transmission system.
FBT Couplers are available in a variety of port configurations, package sizes, coupling ratios, and wavelengths, etc., allowing high flexibility in tailoring the product to suit your precise requirements and application.
All FBT couplers are fully compliant with Telcordia GR-1209 and GR-1221 standards for network applications requiring superior performance and long-term reliability.
Module FBT Coupler without optical fiber connectors can be spliced with optical fibers to get low loss, while Module FBT Coupler terminated with connectors can connect with optical fiber adaptors and enables quicker connection and disconnection than splicing. Module FBT Couplers are widely used for fiber optic communication system in telecommunication, CATV, etc.
