Research And Test Of 4×10G QSFP Optical Module

Due to the increasing demand for bandwidth, the demand of large capacity optical communication devices become more and more urgent. Therefore, as the key part of optical communication devices, optical modules are becoming more and more popular, and the rate of them is higher and higher. QSFP(Small Form-factor Pluggable Quad) optical module: four channel SPF(QSFP) optical module is designed specifically for high density, high speed and the need that can be hot plugged. Such a QSFP optical module, the total data transmission speed arrives 40 Gbps of all 4 channels together. It is located in the physical media related layer of the optical fiber communication Ethernet protocol and the core component of photoelectric and electro-optical conversion. The QSFP optical module can be adjusted to different transmission speeds, and can be applied to Ethernet, channel fiber and InfiniBand standards to solve the short distance data transmission in higher efficiency.This paper selects scheme of 45°FA(Fiber Array)4×10Gbps QSFP optical module. On the basis of this scheme, it is designed and simulated of principle part in QSFP optical to make the circuit design to be the optimal state. In addition, it is analysed and discussed about the effect on performance of the whole optical module to process and coupling process. This process also makes the performance of the optical module to improve in the acsept of process and the speed to produce optical modules which makes it possible to produce optical modules in a large scale. Finally, in order to verify that the optical module performance, this paper puts forward two different testing schemes and platforms. According to the parameters of the optical module, a large number of tests have been made. Through the test, the performance of the optical module fits IEEE 802.3ba and TM-2010 agreement requirements.
