Armored Protection Fiber Coupler

 

Kaiphone's Armored Protection Fiber Couplers are high quality components designed to divide or combine optical signal in optical fiber system. Basing on the fabrication of fused biconical taper (FBT) process, Kaiphone has further reinforced the structure strength by flexible armored cord to secure the reliability of use. The Armored Protection Fiber Couplers are available to be operated over wide range of temperature and durable for more critical operating environment. The operating wavelength is 1310nm and 1550nm. The coupling ratio can change from 1:99 to 50:50.
