SKU: Q112-400G-VSR4-US Categories: , , OEM Equivalent: Arista Q112-400G-VSR4

The US Transceivers compatible Q112-400G-VSR4 is a high-performance 400G QSFP112 optical transceiver designed for very short reach data center and enterprise networking applications. Operating over multimode fiber with a maximum cable distance of 50 meters, this module delivers 400 Gigabit Ethernet connectivity using four parallel lanes of 100G each, making it well suited for high-density switching and top-of-rack deployments.

This transceiver features an MPO/MTP connector interface and VCSEL-based transmitter technology operating at an 850nm wavelength. The QSFP112 form factor enables compact, high-port-density deployments while supporting Digital Diagnostic Monitoring for real-time visibility into optical performance parameters such as temperature, voltage, and optical power levels.

The US Transceivers compatible Q112-400G-VSR4 is fully TAA compliant and meets RoHS, CE, and REACH regulatory standards. It is a cost-effective, drop-in compatible alternative engineered to meet or exceed OEM specifications for mission-critical network infrastructure.
