Product Review
The Arista QSFP-40G-LRL4 transceiver offers compatibility with the SFF-8436 standard and operates over a single-mode fiber with a duplex LC connector, ensuring reliable connectivity for 40GBase Ethernet networks over a maximum link distance of 2km. It is designed to work within a commercial temperature range of 0 to 70 Celsius, with a storage temperature range significantly broader, from -40 to 85 Celsius, facilitating its use in varied environmental conditions. However, its power consumption of up to 3.5W and the requirement for a specific power supply voltage (min -0.5 max 3.6, with a maximum of 4.365) could be a limitation in power-sensitive deployments, despite its benefits of hot pluggability, excellent ESD protection, and low EMI metal construction.
