A chip applied to gpon optical modules and bobs

Abstract

The invention provides a chip applied to a GPON optical module and a BOB. The chip comprises a main chip circuit and an APD boosted circuit, wherein the APD boosted circuit is integrated in the chip. The chip applied to the GPON optical module and the BOB can achieve basic functions of a common optical module chip, and can also provide high-drive voltage needed by GPONBOSA. The boosted circuit is integrated in the chip, so that the design of a main chip peripheral circuit is simplified, and space is saved for a circuit board. Looped control in the prior art needs three pins, the chip only needs one voltage output pin, and accordingly application design of the GPON optical module and the BOB is greatly facilitated.

Description

technical field [0001] The invention relates to a chip, in particular to a chip applied to a GPON optical module and a Bosa on Board (BOB). Background technique [0002] Gigabit-Capable Passive Optical Network (GPON) was first proposed by the FSAN organization in September 2002. Based on this, ITU-T completed ITU-T G.984.1 and G. The formulation of 984.2 completed the standardization of G.984.3 in February and June 2004, thus finally forming the standard family of GPON. The basic structure of the equipment based on GPON technology is similar to that of the existing PON. It is also composed of the optical line terminal (OpticalLine Terminal, OLT) at the central office, and the optical network terminal or optical network unit (ONT / ONU) at the user end to connect the first two devices. It consists of an Optical Distribution Network (ODN) composed of a single mode fiber (Single Mode Fiber) and a passive optical splitter (Splitter) and a network management system. [0003] In t...
