The utility model provides a small, the convenient to use of wavelength division multiplexer, and good reliability.
Description
Technical field
The utility model relates to optical passive component field, more specifically, relates to a kind of core-inset type wavelength division multiplexer.
Background technology
Wavelength division multiplexer is a kind of important passive optical fiber devices in wavelength-division multiplex (WDM) system.The conjunction ripple be made up of wavelength division multiplexer and wavelength drop section are one of basic compositions of system, and it directly determines the quality of the performance parameter such as capacity, reuse wavelengths stability, insertion loss size of system.Wavelength division multiplexer can also derive the critical function device being applicable to WDM for other is multiple, as lambda router---for the full optical communication network of the point-to-point services of broadband service and wavelength addressing; To set out on a journey/lower road device---be used to specify the up/down road of wavelength; Comb filter---for the generation of multi wave length illuminating source and the measurement of spectrum; Wavelength selective switch---the route etc. of different wave length signal, therefore has important theory significance and good market outlook for the research of wavelength division multiplexer and making.
But current wavelength division multiplexer is all light input and output types, volume is comparatively large, and it is not very convenient to use, and loss is higher, poor reliability.
