Final Manufacturer 850nm MM 2/98 Coupling Ration LC/PC 1×3 FBT
Coupler For GPON
FBT Coupler Brief Introduces:
Fiber coupler splits or combines light at operating wavelengths
from 350-2000nm. A variety of fiber types are available including
single-mode, multimode, PM, POF, PCF, Mid-IR fibers. The features
of small size, rugged, low loss, and stable operation allow
integration into instrumentations, systems, and modules. High power
coupler types are also available.

FBT Coupler Compare With PLC Splitter:
| Parameters | FBT Splitter | PLC Splitter |
| Fabrication Method | Two or more pieces of optical fibers are bound together and put on
a fused-taper fiber device. The fibers are then drawn out according
to the output branch and ratio with one fiber being singled out as
the input. | Consists of one optical chip and several optical arrays depending
on the output ratio. The optical arrays are coupled on both ends of
the chip. |
| Operating Wavelength | 1310nm and 1550nm (standard); 850nm (custom) | 1260nm -1650nm (full wavelength) |
| Application | HFC (network of fiber and coaxial cable for CATV); All FTIH
applications. | Same |
| Performance | Up to 1:20– reliable. For larger splits, reliability can become an
issue. | Good for all splits. High level of reliability and stability. |
| Input/Output | One or two inputs with an output maximum of 32 fibers. | One or two inputs with an output maximum of 64 fibers. |
| Package | Steel Tube (used mainly in equipment); ABS Black Module
(Conventional) | Same |
| Input/Output Cable | Bare optical fiber; 0.9mm, 2.0mm, and 3.0mm | Same |
| Package Size | 1×2 to 1×8 smaller size than PLC | More than 1×8, PLC Splitter size is smaller |
| Stability and Reliability | Stability is better | High stability not as FBT Splitter |
