- Products description -
Sharetop’s optical coupler offer very low insertion loss,low polarization dependence and excellent environmental stability Accurate coupling ratio from 50/50 to 1/99 and fiber type 250um bare fiber,3mm and 900um loose tube fiber are available with very tight uniformity.Singlemode standard coupler and wideband coupler components find extensive application to perform power splitting and monitoring functions in all kinds of optical communication systems.
Optical Couplers can couple the optical signals in the coupling area,and then re-distribute the light power.The key parameters include operating wavelength,bandwidth,and excess loss,coupling ratio,PDL and so on.
