Overview
The Arista QSFP-SR4 is a high-performance, four-channel, full-duplex transceiver module designed for 40G Ethernet networks. Utilizing the QSFP+ hot pluggable form factor, this module provides an efficient upgrade path for data centers and high-performance computing networks. The module supports a maximum link length of 100 meters over OM3 Multimode Fiber (MMF) and 150 meters over OM4 MMF, catering to a wide range of deployment scenarios.
At the core of the Arista QSFP-SR4 is the reliable Vertical-Cavity Surface-Emitting Laser (VCSEL) array technology, which ensures high-speed data transmission over multimode fiber cables. This technology is complemented by an unretimed XLPPI electrical interface, which facilitates seamless integration with existing network equipment. The transceiver's single 1x12 MPO receptacle allows for easy and secure fiber cable connections.
Key features include:
- A maximum power dissipation of less than 1.5W, ensuring energy-efficient operation.
- Built-in digital diagnostic functions, including optical power monitoring, which aid in proactive network management and troubleshooting.
- Compatibility with 40GBASE-SR4 Ethernet and the ability to breakout to 4 x 10GBASE-SR Ethernet, providing flexibility for network design and expansion.
The QSFP-SR4 operates efficiently within a commercial temperature range, with a minimum operating case temperature of 0°C and a maximum of 70°C. This broad temperature range ensures reliable performance in diverse operating environments. The transceiver's power supply requirements are modest, with a current of 475mA and a voltage range from 3.135V (minimum) to 3.456V (maximum), with a typical operating voltage of 3.3V.
Data rate per lane is an impressive 10.3125 Gb/s, facilitating 40 Gigabit per second links over multimode fiber. This high data rate makes the QSFP-SR4 an ideal solution for applications requiring high bandwidth, such as 40G Ethernet, Infiniband QDR, and SATA/SAS3 storage networks.
In summary, the Arista QSFP-SR4 transceiver module offers a powerful and efficient solution for building and expanding high-speed networks. Its support for long link lengths, low power consumption, and high data rates, coupled with built-in diagnostic capabilities and a flexible form factor, make it a valuable component for any modern data center or high-performance computing environment.
