Product Review

The HP JL310A offers a QSFP28 form factor with a 100GBase-LR4 interface, supporting a 10km reach over single-mode fiber and equipped with dual-LC connectors, making it suitable for long-distance applications. However, its optical power budget of 7.3 dB, with TX power ranging from -1.3 to 4.5 dBm and RX power from -8.6 to 4.5 dBm, may limit its use in environments with higher loss characteristics. Additionally, the module’s operating temperature range and humidity levels are adequate for standard to industrial environments, but its maximum power consumption of 4.5W could be a concern in densely packed systems where thermal management is critical.
