Hot Sale FTTX FTTH 1X2 FBT Coupler 2 Way SC/APC Mini FBT Fiber Optical Splitter 1310nm or 1550nm
Description
Fiber optic coupler, is a device applicated in optical fiber systems with one or more input fibers and one or several output fibers.For the fused optical splitter,It can be divided into different ratios.such as 50/50 if the split is even, or 80/20 if 80% of the signal goes to one side and only 20% to the other.As a result of its great funciton,Optical splitter is a very important part in passive opitc networks (PON).FTB Fused fiber splitter (coupler) can do Singlemode (1310/1550nm) and Multimode (850nm).
Applications
Optical Fiber Communication Systems Optical Fiber CATV Passive
Optical Network (PON) Optical Amplifiers Optical Access
Networks/LAN Monitoring Systems Optical Fiber Sensor
