Annex
Annex
The polarization maintaining fiber coupler is fabricated by a special polarization-maintaining fiber, which can divide the polarized light into two beams of the same polarization state as the input light. The product has passed the GR-1209-CORE and GR-1221-CORE reliability tests and various environmental tests, and product performance is very good, stable and reliable, having been in a number of national key projects in bulk applications.
