Parameters |
PLC Splitter |
FBT Coupler |
Operating Wavelength |
1260nm -1650nm (full wavelength) |
Single window, dual windows, Triple windows max., 1310/1550±40nm,1490±10nm |
Coupling Ratio |
Equal |
Customized, can be equal or unequal |
Insertion Loss |
The maximum insertion loss of each splitting ratio is stimulated by Telcordia GR-1209 and GR-1221. |
The maximum insertion loss will vary depending on the splitting ratio and increase substantially for those splits over 1:8. |
Performance |
Good for all splits of 1×2, 1×4, 1×8, 1×16, 1×32, 1×64. High level of reliability and stability. |
Up to 1×8, reliable. For larger splitting, reliability will become an issue. |
Input |
One or two inputs |
One or two inputs |
Output |
128 fibers max. |
32 fibers max. |
Package |

Application |
FTTH |
HFC (Hybrid Fiber Coaxial), CATV |
Manufacturing Method |
Consists of one optical chip and several optical fiber arrays depending on the output ports. The optical fiber arrays are coupled on both ends of the chip. |
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 ports and coupling ratio with one or two fibers being singled out as the input. |
Cost |
Lower for more than 1×16 |
Lower for smaller than 1×8 |
