Distribution
FBT Optic Coupler Brief Introduces:
Fused fiber optic couplers (FBT Coupler) are designed for power
splitting and tapping telecommunication equipment, CATV networks,
and test equipment. These kinds of small components are available
individually or integrated into modules for fiber protection
switching, MUX/DMUX, optical channel monitoring, and add/drop
multiplexing applications.
The plastic box FBT optical coupler can choose many options of
connectors, such as Lc, Sc, Fc, St, MU.
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
- Two different splitter grades can be selected: Grade A-fused
biconically tapered, Grade P-standard planar technology
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 |
