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.
1x2 90:10 Split ratio
250μm bare fiber for easy stripping, splicing or terminating.
Also available pre-terminated with LC/UPC, LC/APC, SC/UPC, SC/APC,
FC/UPC, FC/APC, and ST/UPC50/50, 40/60, 30/70, 20/80, 10/90, 5/95,
1/99, 60/40, 70/30, 80/20, 90/10, 95/5, and 99/1.
Available split ratios: 50/50, 40/60, 30/70, 20/80, 10/90, 5/95,
1/99, 60/40, 70/30, 80/20, 90/10, 95/5, and 99/1. In 1x2 or 2x2
splits.

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 |
