Product Description
The Arista QSFP-PLR4 transceiver is a high-density, high-performance module designed for 40 Gigabit Ethernet (40GbE) applications. It utilizes the QSFP+ (Quad Small Form-Factor Pluggable Plus) form factor, which allows for four independent 10Gb/s channels to be aggregated into a single 40Gb/s link. This transceiver is specifically designed for single-mode fiber (SMF) and offers a transmission reach of up to 10 kilometers. A key feature of the QSFP-PLR4 is its use of parallel optics, transmitting data over multiple fibers within a single MPO (Multi-fiber Push-On) connector. This MPO connector typically contains 12 fibers, with 8 used for transmission and reception (4 transmit, 4 receive). The transceiver operates at a wavelength of 1310nm, which is standard for medium-reach SMF applications. It is ideal for connecting switches and routers within data centers, or for data center interconnects (DCI) over shorter distances. This transceiver is crucial for environments requiring high bandwidth and efficient use of fiber infrastructure. Its 10km reach makes it versatile for various deployment scenarios beyond typical intra-data center links. The QSFP-PLR4 is engineered for reliability and performance, supporting demanding network applications that require high throughput and low latency.
