Abstract

The invention discloses an optical module for a wide temperature range and a working temperature adjusting method thereof. The optical module comprises a laser transmitting unit, an MCU (microprogrammed control unit) and a TEC (total electron content) control circuit, wherein the laser transmitting unit comprises a laser and a drive circuit; the optical power of the laser is previously calibrated to the specific optical power range; the MCU is used for determining the working temperature setting value corresponding to the acquired temperature value after acquiring the temperature value detected by a temperature sensor; and the TEC control circuit is controlled to adjust the working temperature of the laser at the corresponding temperature according to the determined working temperature setting value. Since the working temperature of the laser is allowed to be changed along with the ambient temperature within a given temperature range, the heating or refrigerating power consumption can be reduced; and moreover, the optical power is previously calibrated to the appropriate range, so that the optical power can still meet the requirement within the variation range of the working temperature of the laser, the bias current is unnecessary to compensate, and the compensation power consumption can be further saved.

Description

technical field [0001] The invention relates to optical fiber communication technology, in particular to an optical module applied in a wide temperature range and a method for adjusting its working temperature. Background technique [0002] In recent years, with the rapid development of enhanced 8.5G Fiber Channel and 10G Ethernet high-speed optical network protocols, the demand for ultra-high-speed optical transceiver modules is increasing, and the requirements for module port density and power consumption are also increasing . [0003] In the past few years, the 10Gbit / s optical transceiver module has experienced from 300pin MSA, XENPAK (10 Gigabit Ethernet), XPAK, X2, XFP optical module (10 Gigabit Ethernet optical transceiver module) to SFP optical module (Gigabit Ethernet) Ethernet optical transceiver module) + transformation. As an upgraded version of SFP (small form-factor pluggables, small form-factor pluggables), the SFP+ optical module complies with IEEE802.3AE / A...
