All Band Coupler ABS Box FBT Couplers Splitter 1x4

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.

In response to the rapid increase in requirements for passive optical networks (PON), Fiber-Mart now provides a new All Band FBT Couplers Splitters. All Band coupler (ABC) is built by Special technique. The operating bandwidth of the coupler is expanded to 1260-1620nm, and with low excess loss and low PDL.

1x4 All Band Coupler ABS Box FBT Couplers Splitter can splitter the optical signals into 4 parts, and the coupling ratio can be customized.

Key Features

  • Low insertion loss
  • Low polarization dependent loss
  • Optional Split Ratio 20/80, 40/60...(50/50 as default.)
  • All Band operating Wavelength
  • Excellent Environmental & Mechanical Stability
  • Qualified Under Telcordia GR-1221 and GR-1209


  • Optical communication systems
  • FTTH application
