Product Review
The Arista QSFP-40G-SRBD module offers a solid 40GBase SR-BD interface with a dual-LC connector, supporting multimode fiber (MMF) with a reach of up to 100m at the 850nm/900nm wavelength, suitable for short-range, high-density applications. Its optical power budget is well within the expected range for quality transmissions, providing a minimum and maximum TX power of -4.00 to +2.50 dBm and a RX power of -11.00 to +0.50 dBm, ensuring reliable connectivity. However, its operational temperature range is limited to 0°C to 70°C for standard conditions, which may not be sufficient for environments requiring industrial-grade specifications, despite its comprehensive power and data rate specifications.
