The Arista QSFP-40G-PLR4 is packed with impressive hardware specs for any data center or enterprise needing greater bandwidth. Its Quad Small Form-factor Pluggable (QSFP) module has a high-performance electrical interface providing flexibility with both single mode and multimode fiber connections at a range of operating temperatures. The 40 Gigabit module supports 40, 4 x 10G breakout applications and is designed to meet IEEE 802.3ba specifications. The transmitter and receiver components support full-duplex operation, based on the 4 lane NRZ signal rate of 10.3125 Gbps each. Using parallel multi-mode fiber, the module can reach distances of up to 500 meters on OM3 grade cable and 2000 meters on standard OM4 grade cable. The Arista QSFP-40G-PLR4 provides low power consumption, making it a cost-effective solution for environments requiring high performance over distance. The power specification is 0.5W per link, and the device supports a temperature range of -5°C to 85°C, making it ideal for use in harsh environments or industrial applications. Additionally, the optical link budget is 28 dB with the additional power support for up to 500 m. The module features an integrated digital diagnostic monitor interface which allows users to extract valuable information from the modules using a 2-wire serial interface that supports standard SFF-8472 digital diagnostic transceiver implementation. It also includes additional management features such as an advanced control protocol (ACP), module current capacity, laser safety eye safety certification, laser source capability and encryption support. The Arista QSFP-40G-PLR4 module is an invaluable addition to any data center or enterprise requiring high performance over distance with low power consumption. With its impressive hardware specifications, including 4 x 10G breakout applications and a temperature range of -5°C to 85°C makes it ideal for use in professional spaces.
