Specification

Introduction

In this article, we will briefly introduce the 40GBase-eSR4 Ethernet standard and its optical transceivers compatible brands and basic solutions, so that allows viewers to have a more profound understanding for 40GBase-eSR4 technology, better to understand the basic solutions to 40GBase-eSR4. Also to see which brands can be compatible with Cozlink transceivers, helping buyers to buy both compatible and cost-effective products.

What is the 40GBase-eSR4 technology?

40GBASE-eSR4 Transceiver module (00FE325) is a QSFP+ 40 Gigabit Ethernet Quad Small Form-Factor-Plus, hot-pluggable transceiver that plugs into a QSFP+ high-speed data port. It provides 40 Gbps optical Ethernet connectivity for up to 300 meters using OM3 multimode fiber (MMF) cable and up to 400 meters using OM4 multimode fiber (MMF) cable.

40GBase-eSR4 compatible brands:

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

What are the Difference Between 40GBase-eSR4 and 40GBASE-KR4

40GBase-eSR4 40 Gigabit Ethernet transceiver module provides excellent performance in port-dense networks with challenging thermal environments. It also has the capability to breakout into four multimode fiber (MMF) cable with LC duplex connectors.

40GBASE-KR4 is a port type for backplanes. Normally backplanes are board traces, such as Megtron6 or FR4 materials. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 82 and its Physical Medium Dependent PMD in Clause 84. It uses four lanes of backplane delivering serialized data at a rate of 10.3125 Gbit/s per lane.

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-eSR4 Ethernet standard solution. In addition to providing optical transceivers, Cozlink also offers patch cords, fiber optic pigtails and high speed cables for your choice.
