Applicable to 40GBASE-PLR4 Standard Optical Transceiver Models

2016-12-12

Type Of Tutorial

Introduction

In this article we will discuss about the 40GBASE-PLR4 Ethernet standard and its optical transceivers and the brands offer which offers you these and their basic solutions, So you can have a basic understanding for 40GBASE-PLR4 technology to understand the basic solutions to 40GBASE-PLR4. Also, you can check the compatible Cozlink transceivers to get compatible and cost-effective products.

What is the 40GBASE-PLR4 technology?

40GBASE-PLR4 Compatible QSFP+ transceiver support link lengths of 10km, at a wavelength of 1310nm. It primarily enables high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MTP connectors and can also be used in a 4x10G module for interoperability with QSFP+ paralle LR4 interfaces. Digital optical monitoring (DOM) support is present to allow access to real-time operating parameters, which means, we are now by using DOM capable of performing transceiver monitoring and troubleshooting operations.

40GBASE-PLR4 Vs 40GBASE-LR4

As the word implies, one obvious difference between QSFP-40G-LR4 and QSFP-40G-PLR4 is that QSFP-40G-PLR4 has a plus letter “P” in it. In fact, it means parallel. As we all know, in digital data transmission, data transmission usually occurs in two modes—serial and parallel. Parallel transmission is the simultaneous transmission of multiple bits over two or more separate paths, which allow for higher data transfer rates than can be achieved with serial transmission. While serial transmission is the sequential transmission of bits over a single wire frequency or optical path. It reduces the wire cost but slows the transmission speed at the same time. Thus QSFP-40G-LR4 uses the LC connector to achieve serial transmission. While QSFP-40G-PLR4 transceiver terminates with the MPO/MTP connectors to reach parallel transmission

1. QSFP-40G-LR4 (Multiplexing and demultiplexing of the four wavelengths are managed within the device): 1271 nm, 1291 nm, 1311 nm, 1331 nm

2. QSFP-40G-PLR4: 4×1310nm

Conclusion

Since most of the brands are only applicable to their own devices and this makes the third-party compatible optical transceiver really important as it ensures that the equipment of these brands are compatible with each other, Cozlink transceivers are known for these high performance. They are easily compatible with a huge number of brands and the prices you get on Cozlink is really less than the prices on original manufacturer All this makes Cozlink the perfect place for third-party compatible optical transceiver for 40GBASE-PLR4 Ethernet standard solution. In addition to providing optical transceivers, Cozlink also offers patch cords, fiber optic pigtails and high speed cables for your choice.
