What's the interface and kind of 40G QSFP+ transceiver moule?

40G QSFP+ transceiver moule interface

1. LC interface

The LC interface is used with the LC fiber connector. The LC fiber connector is made of a modular jack (RJ) latch mechanism that's simple to operate and includes a smaller size. How big is 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 machine.

2. MPO/MTP interface

The MPO/MTP interface is connected to the MPO/MTP fiber connector. The MPO (Mulit-fiber ACCOMPLISH) fiber connector is mechanically snapped into place. The optical performance and mechanical performance of the MTP fiber connector derive from 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

1. 40G SR4 QSFP+ transceiver moule

The interface of the Avago AFBR-79EEPZ transceiver moule is MPO. Its working principle is that whenever the signal is usually transmitted at the transmitting end, the electrical signal is first changed into an optical signal by the laser array. When getting the signal at the receiving end, the photodetector array converts the parallel optical signal Into parallel electrical signals.

2. 40G LR4 QSFP+ transceiver moule

The interface of the 40G LR4 QSFP+ transceiver moule is LC duplex, which includes the benefits of high density, higher rate, large capacity, low priced, 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. If they reach the getting end, these transmitted signals are decomposed into four channels with a transmission rate of 10 Gbps by the demultiplexer, and the PIN detector or transimpedance amplifier performs data flow. Recover, and then distribute the optical signal.

3. 40G LR4 PSM transceiver moule

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

Differences between cisco GLC-T and cisco GLC-TE

 Cisco GLC-T, GLC-TE and SFP-GE-T optical modules are all Gigabit port optical modules with RJ45 interface and 100m transmission distance. They are cost-saving solutions for Gigabit Ethernet connection in data center, access network and storage area network applications. Therefore, these three types of optical modules are often difficult to distinguish. In fact, the transmission effect of these three optical modules is the same, which optical module can achieve Gigabit transmission, but it is certainly noteworthy that the original Cisco GLC-T and SPF-GE-T optical modules were terminated on June 1, 2017 and replaced by GLC-TE optical module. SFP-GE-T optical module with NEBS 3 ESD function needs to be selected if it is traded directly with the telecommunications company (which requires NEBS).The price of GLC-T and GLC-TE optical modules is low, and they can also meet the needs of Gigabit Ethernet. The Cisco Gigabit optical modules provided by Easy Communications can meet a large number

Why the sfp transceiver not work

 The failure of the sfp optical module is divided into the failure of the transmitter and the failure of the receiver. Through the analysis of the main causes of the phenomenon, the most likely problems are mainly concentrated in the following aspects: The optical port of the  1000base SFP transceiver  is contaminated and damaged Because of the pollution and damage of the optical interface of the module, the loss of the optical link is increased, so that the optical fiber link is unreachable. The main reasons for this phenomenon are the following four points: 1. The optical port of the SFP optical module has been exposed to the environment for a long time, resulting in contamination and contamination of the SFP optical port; 2. The end face of the fiber jumper connected to the  Cisco SFP-10g-sr  optical module has been contaminated, and the SFP optical port provides been contaminated; 3. Improper operation of the end face of the optical connector with pigtails, scratching of the finish
