Abstract

The invention discloses an EPON Triplexer OLT laser protection module comprising a microprocessor. The microprocessor is connected with a temperature control drive circuit that is connected with a Triplexer laser. And the Triplexer laser includes a 10G EML laser and a 1.25 G DBF laser, wherein a semiconductor cooler and a temperature control module are arranged inside the 10G EML laser. Besides, the microprocessor includes a temperature collection module inside an optical module. According to the invention, the microprocessor controls the temperature of the 10G EML laser to be at 45 DEG C by the temperature control drive circuit; the microprocessor uses a 10G laser drive circuit and a 1.25 G laser drive circuit to respectively control the 10G EML laser and the 1.25 G DBF laser to work at a temperature range of from 70 DEG C and 85 DEG C, thereby realizing overheating protection on the Triplexer laser.

Description

technical field [0001] The invention relates to the technical field of 10G Ethernet passive optical network (10G EPON), in particular to an EPON Triplexer OLT laser protection module applied in a high-speed single-fiber three-way XFP 10G EPON OLT optical module. Background technique [0002] With the promotion and popularization of FTTx (fiber-to-user terminal) technology, high-speed broadband services are gradually changing people's life and work styles, SOHO will be very easy to implement, and family high-definition interactive film and television programs, telemedicine, and distance education are no longer far away . People's demand for bandwidth continues to increase, making the bandwidth provided by the current 1G EPON technology gradually unable to meet the needs of broadband services. Therefore, the 10G EPON technology that can provide higher bandwidth has become a very attractive solution, and the 10G EPON OLT optical module is an important part of the system. In t...
