Customized 2x2 Multimode Single Mode Fiber Optic Coupler 1310nm
Optic Coupler Brief Introduces:
Single-mode wideband couplers have 80nm bandwidth, compared to 40nm
of standard single-mode couplers. This product has very low excess
loss and high-temperature stability.
Coupling ratio can be specified. Couplers working at center
wavelength other than 1550nm or 1310nm can also be provided.

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 |
