Multi-channel, parallel transmission optical module,and methods for manufacturing and application thereof

Abstract

The invention discloses a high speed optical module, especially the multi-channel, the single mode and the parallel transmission optical module of the optical communication field. The optical module comprises a pedestal, a first transmission optical sub apparatus (TOSA), a second transmission optical sub apparatus (TOSA), a third transmission optical sub apparatus (TOSA), a fourth transmission optical sub apparatus (TOSA), and an MT fiber connector. The TOSA can be the TO-38 TOSA for a 10G DFB chip or FP chip. By means of single mode communication, the optical module can realize the transmission distance greater than 10 kilometers. Besides, for further simplification of the single-mode fiber, the invention uses a 12-chip MT fiber connector, wherein the four fiber connectors are respectively in output connection with the corresponding LC standard fiber stub and TOSA so that the optical module also realizes high speed and long-distance transmission, high capacity, small volume and light weight, and can also be widely applied to the high speed optical communication.

Description

technical field [0001] The invention relates to the field of optical communication. More specifically, embodiments of the present invention are applicable to high-speed optical modules, especially multi-lane, parallel transmission, small form-factor pluggable (SFP) optical modules and methods of making and using the same. Background technique [0002] In 1964, Gordon Moore predicted that the number of transistors that could be placed on an integrated circuit would double at a specific time frame, usually every 18 months or every 2 years. Gilder's Law tells us that while computing power doubles every 18 months (Moore's Law), communication power doubles every 6 months. Bandwidth is growing at least 3 times faster than computing power. In 1999, Nortel CEO, John Ross, asserted that the growth rate of Nortel network was twice that of Moore's Law, doubling the capacity of the fiber optic system but halving the cost every nine months. [0003] The above predictions have been con...
