| Truly Fused Tree & Star Couplers. |
- Overview
- Single Wavelength
- Wavelength Flattened
- Wavelength Independent
Gould's Truly Fused Single Wavelength 1XN and NXN couplers are manufactured as star devices with continuous fibers. Tree couplers are made by terminating the unused ports for minimal back reflection. |
