Wellsion Fiber Optic Communication Co.,Ltd

Built by asymmetric coupling technique, Three-window fiber optic fused coupler (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 PDL
• Dual operating window
• High stability and reliability

Applications:

• Optical communication systems
• CATV
• FTTH
