Single Mode Fiber Optic Cable Splitter 1310nm 1550nm Dual Window Coupler
Single Mode Fiber Optic Cable Splitter 1310nm 1550nm Dual Window Coupler
Description
1x2 Single Mode 1310/1550nm Dual Window Coupler 50:50 or 40:60 or 1:99 manufactured by ANC International Co., Limited splits and combines light simultaneously in both 1310nm and 1550nm wavelength regions and offer excellent performance over 80nm bandwidth. 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. Single mode dual window coupler find extensive application to perform power splitting and monitoring functions in all kinds of optical communication systems.
