介绍了一种稳定的单模透射式8×8星星耦合器的制作和性能。该器件具有非常低的额外损耗（0.13 dB）、良好的耦合均匀性（0.73 dB）和低的近端串扰（>64 dB）。该星星耦合器是由八个长度的单模光纤，通过形成适当的光纤对之间的3分贝熔融耦合区。给出了插入损耗测量表，以及显示1.2和1.7 μm之间的波长响应的图表。
The fabrication and performance of a stable single-mode transmissive 8×8 star coupler is described. The device exhibits very low excess loss (0.13 dB), good coupling uniformity (0.73 dB) and low near-end crosstalk (>64 dB). The star coupler is fabricated from eight lengths of single-mode fibre, by forming 3 dB fused coupling regions between appropriate fibre pairs. A Table of insertion loss measurements is presented, together with graphs showing the wavelength response between 1.2 and 1.7 μm.
