The US Transceivers compatible JH645A is a 10GBASE-SR SFP+ optical transceiver module designed for high-performance 10 Gigabit Ethernet applications. Built in the compact SFP+ form factor, this module operates at an 850nm wavelength over multimode fiber and supports link distances of up to 300 meters, making it well suited for short-reach data center and enterprise deployments.
This TAA compliant module delivers reliable 10.3125 Gbps data transmission and is fully compatible with Arista networking equipment that references the JH645A part number. It features an LC Duplex connector interface and supports Digital Diagnostic Monitoring (DDM) for real-time visibility into optical performance parameters such as temperature, voltage, and optical power.
Manufactured to meet IEEE 802.3ae and SFP+ MSA standards, the US Transceivers compatible JH645A is tested to ensure drop-in interoperability, consistent signal integrity, and low power consumption across commercial operating temperature ranges.
