Four performance parameters of fiber optic couplers

What parameters define the performance of a coupler? Key parameters are insertion loss (<0. 3–1 dB per port), splitting ratio accuracy, polarization‑dependent loss (55 dB), and wavelength uniformity. 671 and Telcordia GR‑1209/1221. Lower insertion loss values indicate better performance. Coupling Ratio: Specifies the. This tab provides a brief explanation of how we determine several key specifications for our 1x2 couplers. 1x2 couplers are manufactured using the same process as our 2x2 fiber optic couplers, except the second input port is internally terminated using a proprietary method that minimizes back.
