A method for automatically calibrating the received power of a sensor by a sensor test system

Abstract

The invention discloses a BOB test system and a method for automatically calibrating BOB receiving power, which solves the problems of complicated operation, high precision and high labor cost in the calibration mode of BOB module receiving power. The present invention includes a host computer, an optical line terminal connected to the host computer, a BOB module and an integrated identification system integrated with an optical attenuator inside, and an optical splitter connected to the optical line terminal and the optical attenuator through an optical fiber at the same time; the optical The attenuator is connected to the BOB module through optical fiber. The invention is reasonable in design and convenient in operation. Through the effective combination of software and hardware, the automatic calibration of BOB receiving power is realized, which not only has a high degree of automation, but also has high calibration accuracy, and effectively reduces unnecessary labor cost input. Therefore, this invention The invention has high application value.

Description

technical field

[0001] The present invention relates to a BOSA on board (BOB On Board, BOB for short) technology, in particular to a method for automatically calibrating BOB receiving power by a BOB testing system. Background technique

[0002] Although the network has fully popularized the public, ADSL technology is still the mainstream. With the continuous expansion of the scope of network use, users have higher and higher requirements for the network, and with the reduction of the production cost of optical fiber cables, both the majority of users, equipment manufacturers and operators have all set their sights on optical fiber network access. into technology.

[0003] However, the high price of optical fiber access network equipment has always been the key and difficult problem for the popularization of fiber-to-the-home. Therefore, finding a low-cost technical equipment that can be produced and used has become the focus of current access network research technology. B...
