Three-Window Coupler Three-Window Coupler 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 is widely used for communication systems, CATV, FTTH, where multiple optical signals pass through single fiber. Features: • Low excess loss • Low insertion loss and PDL • Three operating windows • High stability and reliability Applications: • Optical communication systems • CATV • FTTH Three-Window Coupler Specifications: 1. The above specification is without connector 2. Other specifications can be made on customer request. Henan Shijia Photons Technology Co., Ltd. www. sjphotons. com
