Coupler & Splitter
Three-window coupler (TWC) is newly developed by Raysciecen. Built by asymmetric coupling technique,
TWC operating bandwidth is expanding to 1310nm, 1490nm and 1550nm three communication windows.
The TWC coupler has the same coupling ratio on 1310, 1490 and 1550nm communication windows, with
low excess loss and low PDL. TWC are widely used for communication systems, CATV, FTTH, where
multiple optical signals pass through single fiber.
The PLC splitter family( 1x4, 1x8, 1x16, 1x32, 2x16, 2x32 ) has two classes. P-grade and S-grade, with specifications that are tailored for different applications and markets. All splitter's feature guaranteed performance specifications and high reliability that surpass Telcordia requirements
