Introduction

In this article we will discuss about the 40GBASE-LRL4 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-LRL4 technology to understand the basic solutions to 40GBASE-LRL4. Also, you can check the compatible Cozlink transceivers to get compatible and cost-effective products.

What is the 40GBASE-LRL4 technology?

40GBASE LRL4 QSFP+ Module supports link lengths of up to 1km over a single mode fiber with 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. It combines the higher density attractions of parallel modules with some of the key advantages normally associated with SFP+ based modules. It is intended for use short reach applications in switches, routers and data center equipment where it provides higher density and lower cost when compared with standard SFP+ modules.

What are the Difference Between 40GBASE-LRL4 and 40GBASE-PLRL4?

40GBASE-LRL4 QSFP (Multiplexing and demultiplexing of the four wavelengths): 1270 nm, 1290 nm, 1310 nm, 1330 nm. For 40GBASE-LRL4 QSFP, the 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.

40GBASE-PLRL4 QSFP: 4 x 1310nm. For 40GBASE-PLRL4 QSFP, the 4x10G connectivity is achieved using an external 12-fiber parallel to 2-fiber duplex breakout cable, which connects the 40GBASE-LR4 module to four 10GBASE-LR optical interfaces. QSFP-40G-PLRL4 is optimized to guarantee interoperability with any IEEE 40GBase-LR4 and 10GBase-LR (in 4x10G mode).

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-LRL4 Ethernet standard solution. In addition to providing optical transceivers, Cozlink also offers patch cords, fiber optic pigtails and high speed cables for your choice.
