Description
● Fused Biconic Taper (FBT) Splitter/Coupler:
Fused Biconic Taper (FBT) Splitter, also be called fiber coupler, based on the traditional technology, it is to bundle together two or more optical fibers, and then pull the cone machine melt stretching, and real-time monitoring the change of the ratio, spectral ratio requirements after melt stretching, one side retain a single fiber (the rest of the cut) as input, the other end is a multi-channel output. As one of the key components for GPON FTTX networks, optical splitters can be placed in the Central Office or in one of the distribution points (outdoor or indoor) because the FBT splitters are highly stable for multiport optical signal splitting with low insertion loss. FBT couplers are designed for power splitting and tapping in telecommunication equipment, CATV network, and test equipment.
PancomLink's Multimode Fiber Optic Coupler (MM FBT Coupler ) are fabricated from multimode fibers with core diameters of 50um ,62.5um or 100um. Standard multimode couplers are commonly used in short distance communications with LED sources operating at 1310nm or 850nm. Multimode couplers are wavelength independent over a broad range of wavelengths (600nm to 1610nm) with uniform modal power distribution launch condition, multimode tree/star couplers NX4(n=1,2,4), NX8(n=1,2,8), NX16(n=1,2,16) port ratios are available.
● Features:
►Low insertion loss, High return loss optional;
►Low polarization dependent loss;
►Compact for small application areas like in closure or splice trays;
►Excellent environmental & mechanical stability;
►Qualified under Telcordia GR-1221 and GR-1209.
● Application:.
►Long-haul Telecommunications;
►FTTH Network/Deployment;
►CATV Systems & Fiber Optic Sensors;
►Local Area Network (LAN);
►Passive Optical Networks (PON);
►Test equipment.
