1x3 Single Mode Triple Window Fiber Optic Coupler 1310nm 1550nm
1x3 Single Mode Triple-Window Fiber Optic Coupler 1310&1550nm
Three Window Optic Coupler Brief Introduces:
1X3 and 3X3 offer very low insertion loss, low polarization dependence, and excellent environmental stability. Accurate coupling ratio's from 50/50 to 1/99 are available with very tight uniformity. The Singlemode Standard Coupler components perform power splitting and monitoring functions in all kinds of optical communication systems.
1× 3 FIber Optic Coupler Features& Benefits:
- Low insertion loss
- Low polarization dependent loss
- High Return Loss
- Excellent Environmental & Mechanical Stability
- Compact for small application areas like enclosure or splice trays
- 1x2, 1x3, 1x4 configurations of splitters are available
- Two different splitter grade can be selected: Grade A-fused biconically tapered, Grade P-standard planar technology
- Steel tube-compact size
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 |
