Introduction

In this article, we will briefly introduce the 40GBASE-PLRL4 Ethernet standard and its optical transceivers compatible brands and basic solutions, so that allows viewers to have a more profound understanding for 40GBASE-PLRL4 technology, better to understand the basic solutions to 40GBASE-PLRL4. 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-PLRL4 technology?

40GBASE-PLRL4 QSFP PLRL4 refers to QSFP parallel LRL4. In general, digital data transmission can occur in two basic modes: serial or parallel. In parallel transmission, multiple bits are sent simultaneously on different channels within the same cable, or radio path, and synchronized to a clock. 40GBASE-PLRL4 compatible QSFP+ transceiver provides 40GBase-PLR4 throughput up to 10km over single-mode fiber (SMF) at a wavelength of 1310nm using a MPO connector.

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

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).

40GBASE-LRL4 QSFP (Multiplexing and DE multiplexing 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 DE multiplexing of the four wavelengths are managed within the device.

Conclusion

Due to the different brand is only applicable to their own devices, makes third-party compatible optical transceiver is very important, it ensures that two different brands of equipment are compatible with each other. Cozlink transceiver has high performance; it can fully compatible with different brands, and Cozlink price is much less than the original manufacturer, so it is a perfect third-party compatible optical transceiver for 40GBASE-PLRL4 Ethernet standard solution. Apart from transceivers, Cozlink also provides all kinds of patch cords, pigtails, high speed cables for your choice.
