Singlemode Dual Window Coupler/Splitter 1X2 2X2 |
The singlemode dual window coupler/splitter 1X2 2X2 offer very low insertion loss, low polarization dependence and excellent environmental stability. Accurate coupling ratio from 50/50 to 1/99, fiber type 250um bare fiber, 3mm and 900um loose tube fiber are available with very tight uniformity in a wide wavelength range of both 1310 nm and 1550 nm windows. Singlemode dual window wavelength flattened couplers find extensive application to perform power splitting and monitoring functions in all kinds of optical communication systems. |
