Introduction
In this article, we will briefly introduce the 40GBASE-CSR4 Ethernet standard and its optical transceivers compatible brands and basic solutions, so that allows viewers to have a more profound understanding for 40GBASE-CSR4 technology, better to understand the basic solutions to 40GBASE-CSR4. 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-CSR4 technology?
The Cisco 40GBASE-CSR4 QSFP Module is similar to the 40GBASE-SR4 interface but it extends supported link lengths to 300m and 400m respectively on laser-optimized OM3 and OM4 multimode fiber cables. Each 10-gigabit lane of this module is compliant to IEEE 10GBASE-SR specifications. This module can be used for native 40G optical links over 12-fiber ribbon cables with MPO/MTP connectors, or in 4x10G mode with ribbon to duplex fiber breakout cables for connectivity to four 10GBASE-SR interfaces. Maximum channel insertion loss allowed is respectively 2.6dB over 300m of OM3 cable or 2.9dB over 400m of OM4 cable.

What are the Difference Between 40GBASE-CSR4 and 40GBASE-LR4?
10BASE-T is the IEEE standard that defines the requirement for sending information at 10 Mbps on unshielded twisted-pair cabling, and defines various aspects of running Ethernet on this cabling.
The 40GBASE-LR4 QSFP module supports link lengths of up to 10 kilometers over a standard pair of G.652 single-mode fiber with duplex LC connectors. The 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and DE multiplexing of the four wavelengths are managed within the device.
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-CSR4 Ethernet standard solution. In addition to providing optical transceivers, Cozlink also offers patch cords, fiber optic pigtails and high speed cables for your choice.
