40G QSFP+ transceiver moule interface

 LC interface

The LC interface is used in conjunction with the LC fiber connector. The LC fiber connector is made of a modular jack (RJ) latch mechanism that's easy to operate and has a smaller size. The size of the pins and sleeves used are ordinary SC , FC, etc. half of the size used is 1.25mm. Therefore, this interface can increase the density of fiber optic connectors in the system

 MPO/MTP interface

The MPO/MTP interface is connected to the MPO/MTP fiber connector. The MPO (Mulit-fiber Pull Off) fiber connector is definitely mechanically snapped into place. The optical performance and mechanical performance of the MTP fiber connector are based on the MPO connector. To a certain extent, the MPO/MTP interface has better transmission performance, lower loss, and higher fineness

Types of 40G QSFP+ transceiver moules

. 40G SR4 QSFP+ transceiver moule

The interface of the 40G SR4 QSFP+ transceiver moule is MPO/MTP. Its working principle is that when the signal can be transmitted at the transmitting end, the electrical signal is first converted into an optical signal by the laser array. When receiving the signal at the getting end, the photodetector array converts the parallel optical signal Into parallel electrical signals

. 40G LR4 QSFP+ transceiver moule

The interface of the Cisco WSP-Q40GLR4L transceiver moule is LC duplex, which has the advantages of high density, high rate, large capacity, low cost, and low power consumption. Its working principle is that the laser driver modulates the wavelength of serial data. The multiplexer will The modulated optical signals are combined and transmitted. When they reach the receiving end, these transmitted signals are decomposed into four channels with a transmission rate of 10 Gbps by the demultiplexer, and then the PIN detector or transimpedance amplifier performs data flow. Recover, and send out the optical signal

. 40G LR4 PSM transceiver moule

The interface of the 40G LR4 PSM transceiver moule is MPO/MTP, using Parallel Single Mode (Parallel Single Mode Technology, PSM). Its working principle is similar to the 40G SR4 QSFP+ transceiver moule. The difference is certainly that the 40G LR4 PSM transceiver moule transmits parallel optical signals. It is transmitted in parallel through 8 single-mode optical fibers
