FTTH High performance FBT fiber optic splitter coupler

Short Description:

FBT is the short form of Fused Biconic Taper splitter, it’s based on the traditional technology, 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.

Product Description

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 coupers 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.

Product Features

1. Good uniformity and low insertion loss
2. Low Polarization Dependent Loss
3. Excellent Mechanical
4. Operating environment: -40ºC to +85ºC
5. High Polarization Extinction Ratio & Excellent Uniformity
6. Fiber input: 0.9mm or 250μm fiber for choice
7. Fiber output: 250μm bare fiber (It is benefit for splicing)G.657A Fiber

Product Applications

1. Fiber to the point (FTTX)

2. Fiber to the home (FTTH)

3. Passive optical networks(PON, GEPON)

4. Local area networks (LAN)

5. Cable television (CATV)

6. Test equipment
