Steel Tube Single Mode 1x2 2x2 Dual Window Fiber Optic Coupler
Steel Tube Single-mode 1x2, 2x2 Dual Window Fiber Optic Coupler (FBT Coupler)
Optic Coupler Brief Introduces:
Fiber Optic FBT Splitter or Coupler (SM, 1310 ~ 1550 nm) is designed to combine or distribute optical signals from single/multiple inputs to single/multiple outputs bi-directionally in optical fiber systems. FBT splitter makes use of precision technology and single-mode optical couplers (splitters) are designed for optical power splitting in cable television networks, passive optical networks (PON), control and measuring equipment, in local networks, and telecommunications.
This single-mode dual window FBT Splitter or Coupler operates at wavelengths of 1310 nm and 1550 nm and has a low polarization-dependent loss (PDL) and low insertion loss. Also, customers can specify the required coupling ratios for their FBT Splitters.
1× 2 Fiber Optic Coupler Features& Benefits:
1) Low insertion loss
2) Low PDL
3) Compact design
4) Good channel-to-channel uniformity
5) High directivity
6) High reliability and stability
7) Various coupling ratios are available
