A gpon network olt optical module based on standard sfp package

Abstract

The present invention is applicable to the field of optical communication, and provides a GPON network OLT optical module based on a standard SFP package, including a pluggable electrical interface circuit, a microprocessor circuit, a zeroth switch, a first switch, a zeroth photoelectric transceiver, a A photoelectric transceiver, the zeroth monitoring circuit, and the first monitoring circuit. In the present invention, the microprocessor circuit receives configuration instructions through the pluggable electrical interface circuit, and correspondingly controls the pin configuration and configuration of the pluggable electrical interface circuit. The opening and closing states of the zeroth switch and the first switch control the optical module to enter one of the two working modes, which can be inserted into the early OLT equipment as a conventional single-channel OLT optical module, and can also be used in new equipment that supports dual-channel OLT ports. It is used as two independent OLT optical modules, so that one GPON OLT optical module supports the design of two different working scenarios. The operator's development, operation and maintenance costs.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a GPON network OLT optical module based on standard SFP packaging. Background technique [0002] Now the OLT (Optical Line Terminal) optical modules used in GPON (Gigabit Passive Optical Network) networks are generally packaged in SFP (Small Form-factor Pluggable, hot-swappable small package modules), and can only be used as single-channel OLT optical modules. , the internal structure of the OLT optical module commonly used for GPON is as follows figure 1 Shown, including SC photoelectric transceiver, monitoring circuit, microprocessor circuit, SFP interface. The voltage Vcc terminals of the SFP interface are respectively connected to the SC photoelectric transceiver, the monitoring circuit, and the microprocessor circuit for power supply. The data port of the SC photoelectric transceiver and the signal port of the microprocessor circuit are also conne...
