Abstract

The invention discloses a BOB (BOB on Board) testing system and a method for automatically calibrating BOB receiving power, and aims to solve the problems of complex operation, low accuracy and high labor cost in the calibration way of the BOB module receiving power. The BOB testing system comprises an upper computer, and an optical line terminal, a BOB module and an integrated authentication system integrated with an optical attenuator which are all connected with the upper computer, and an optical splitter which is synchronously connected with the optical line terminal and the optical attenuator through an optical fiber, wherein the optical splitter is connected with the BOB module through the optical fiber. The BOB testing system is reasonable in design and convenient to operate. Through effective combination of software and hardware, automatic calibration of the BOB receiving power is realized; the automatic degree and calibration accuracy are high; and unnecessary labor cost investment is effectively reduced. Thus, the BOB testing system and the method have very high application values.

Description

technical field [0001] The present invention relates to a BOSA on board (BOB On Board, referred to as BOB) technology, in particular to a BOB test system and a method for automatically calibrating BOB receiving power. 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 technol...
