China-Fiber was founded in 2002 by several senior engineers. We are firstly manufacture fiber passive component, fused coupler is our first product. As well as manufacture, we also distribute some high end instrument and unique fibers, lasers and relevant product from the beginning. At 2007, we began to design and manufactured light source. It started from DFB narrow line width laser. Now we are product include broadband light sour (SLED, LED, ASE), narrow line width light source (10MHz, 1MHz, 100K Hz, 10KHZ DFB laser), fiber laser light source (1550nm, and 1060nm)，high power pump laser, tunable lasers, and EDFA and CATV light source. The passive component we provide optical switch, isolator, circulator collimator and splitter/coupler, VOA, and PM devices. We believe the quality, cost and service. We provide the client high quality, best price and satisfying service
