Introduction

In this article we will discuss about the 40GBASE-SR 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-SR technology to understand the basic solutions to 40GBASE-SR. Also, you can check the compatible Cozlink transceivers to get compatible and cost-effective products.

What is the 40GBASE-SR technology?

40GBASE-SR ("short range") is a port type for multi-mode fiber and uses 850 nm lasers. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 82 and its Physical Medium Dependent PMD in Clause 86. It uses four lanes of multi-mode fiber delivering serialized data at a rate of 10.3125 Gbit/s per lane. 40GBASE-SR has a reach of 100 m on OM3 and 150m on OM4. There is a longer range variant 40GBASE-eSR4 with a reach of 300 m on OM3 and 400 m on OM4. This extended reach is equivalent to the reach of 10GBASE-SR.

40GBASE-SR compatible brands:

Cozlink products and services: a convenient shopping platform, custom Logo, packaging, etc.

What are the Difference Between 40GBASE-SR and 40GBASE-FR?

The 40GBASE-SR QSFP module supports link lengths of 100 and 150 meters, respectively, on laser-optimized OM3 and OM4 multimode fibers. It primarily enables high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MPO/MTP multifiber female connectors. 40GBASE-SR is optimized to guarantee interoperability with any IEEE-compliant 40GBASE-SR module. 40GBASE-SR does not support FCoE.

40GBASE-FR is a port type for single-mode fiber. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 82 and its Physical Medium Dependent PMD in Clause 89. It uses 1550 nm optics, has a reach of 2 km and is capable of receiving 1550 nm and 1310 nm wavelengths of light. The capability to receive 1310 nm light allows it to inter-operate with a longer reach 1310 nm PHY should one ever be developed. 1550 nm was chosen as the wavelength transmission to make it compatible with existing test equipment and infrastructure.

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-SR Ethernet standard solution. In addition to providing optical transceivers, Cozlink also offers patch cords, fiber optic pigtails and high speed cables for your choice.
