單模多光纖準直器
準直器是用來縮小光束的裝置，使光束的空間橫截面更小;或者用來聚焦一束光并重新引導它，使它對準不同的方向，使其平行/準直。

Note:
1) At 10mm working distance and single wavelength. Dual wavelength IL will increase by 0.1dB.
2) At < 1mm reflection working distance (RWD) and single wavelength with 100% reflection mirror.
All values referenced are without connector.
