5nm fused taper ultra-narrowband wavelength division multiplexer 1550/1555nm bandwidth ±0.5nm

Fused taper ultra-narrowband wavelength division multiplexer refers to a one-time taper wavelength division multiplexer with a wavelength interval of 5nm. Fused taper wavelength division multiplexing refers to a technology that transmits multiple wavelength optical signals in one optical fiber at the same time. With the development of optical communication systems, it is widely used in optical fiber sensors, optical fiber lasers, optical fiber amplifiers (EDFA), high-speed multi-wavelength transmission, etc. In the wavelength range, an optical communication system with multiple wavelengths on a pair of optical fibers or a single optical fiber is required, where the interval between each wavelength is 5nm. In this case, the wavelength division multiplexing with a smaller channel interval in the same window is called ultra-narrowband wavelength division multiplexing SUNBWDM, which has low loss, good stable performance, simple maintenance and convenient power supply.

Product features：Small size、 Low insertion loss、 One-time melting and taper, easy maintenance、 Good stability

Application area：Fiber amplifier 、Fiber laser Network signal CATV, HDTV High-speed 、 multi-wavelength transmission system
