Loss analysis device of passive device

Abstract

The invention discloses a loss analysis device of a passive device, comprising a multi-wavelength light source, an optical switch, a polarization controller (PC), a shunt, a return loss test module, an optical power meter module and a singlechip, wherein the multi-wavelength light source is used for providing multi-wavelength lasers with stable power; the optical switch is used for selecting one of the multi-wavelength lasers for output; the PC is used for changing the polarization state of the lasers; the shunt is provided with a first end, a second end and a third end; the return loss test module is used for testing optical power reflected by the input end of the passive device to be tested; the optical power meter module is used for testing the optical power of the output end of the passive device; and the singlechip is used for controlling the laser output of the multi-wavelength light source, the laser selection of the optical switch and the changes of the PC for the laser polarization state, receiving data tested by the return loss test module and the optical power meter module, and processing the data. The loss analysis device is a multifunctional device which integrates the functions of a stable distributed feedback (DFB) light source, the optical power meter module, a plugging-return loss test set, and a polarization dependent loss (DPL) tester into a whole.

Description

technical field [0001] The invention relates to a passive device loss analysis device, in particular to a multi-channel passive device loss analysis device. Background technique [0002] As the price of international copper raw materials has risen sharply, while the price of optical fiber has fallen sharply, it is the general trend to "retreat copper and advance light". However, the traditional voice service has been fully developed, and it is difficult to grow any more. Broadband access is the bright spot in the business of fixed network operators. The current ADSL seems to have come to an end in terms of bandwidth mining, and FTTH (Fiber To The Home , fiber-to-the-home) is the most promising to achieve triple play, resulting in new business growth. The integration of the three networks has been implemented theoretically. The bandwidth requirements of users drive the development of FTTH, and the development of FTTH provides a good platform for new network services. develo...
