Introduction

In this article we will discuss about the 40GBASE-SR4 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-SR4 technology to understand the basic solutions to 40GBASE-SR4. Also, you can check the compatible Cozlink transceivers to get compatible and cost-effective products.

What is the 40GBASE-SR4 technology?

40GBASE-SR4 ("short range") is a port type for multi-mode fiber and uses 850 nm lasers. Its Physical Coding Sub layer 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-SR4 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 QSFP+ AOC VS 40GBASE SR4 QSFP+ Transceiver

40GBASE-SR4 QSFP+ transceivers is now being widely used for 40G network interconnection in short distance. This is a highly integrated component which has small size and uses four channels to support conversions between optical signals and electrical signals over a high data rate up to 40G. However, another component which can replace this transceiver in network interconnection becomes popular in data center application. It is 40GBASE QSFP+ AOC (active optical cable).

AOC is a kind of direct attached cable (DAC), which is available in 10G, 40G and even 120G. 40GBASE QSFP+ AOC contains a QSFP+ connector on one end and one QSFP+ connector on the other end which are linked by a length of fiber optic cable. There are also fanout versions of 40GBASE QSFP+ AOC with one end connected with a QSFP+ connector and the other end with several SFP+/XFP connectors. It looks like a fiber optic patch cable, but, it has a similar function of optical transceiver, and also can transmission signals with its fiber optic cable. 40G AOC removes the process of two modules, which must be done in a 40G interconnection using 40G SR4 QSFP+ transceiver. It seems that both 40G AOC and 40G transceiver are good solutions for interconnection. However, everything has its Pros and Cons. Figure out the one that fits your application is the most reasonable way. The following is to offer comparison between these two components for your references.

Conclusion

As a lot of brands are only compatible with their own devices and this is where the third-party compatible optical transceiver becomes really important to insure ensures that the brands are equipment of these brands are compatible with each other, Cozlink is one of the most trusted source to provide high performance transceivers which are compatible with a lot of different brands, Also, the prices you get on Cozlink is much less than the original manufacturer. All this makes stands out Cozlink as the perfect place for third-party compatible optical transceiver for 40GBASE-SR4 Ethernet standard solution. Not just optical transceivers, you can also find fiber optic pigtails and high speed cables for your choice on Cozlink.
