单模多光纤准直器
准直器是用来缩小光束的装置，使光束的空间横截面更小;或者用来聚焦一束光并重新引导它，使它对准不同的方向，使其平行/准直。

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.
