Add reliable and cost-effective network connectivity over fiber with this QSFP module

Maintain Reliable 400G Connectivity in Commercial Environments

Deploy long‑reach 400G links with confidence using a QSFP transceiver designed for stable operation within a commercial temperature range (0°C to 70°C). Operating over single‑mode fiber at 1310nm, it supports distances up to 500m (1640ft) and delivers consistent performance across data centers, telecom rooms, and enterprise edge deployments.

Reduce Vendor Lock‑In with Broad Interoperability

Ensure seamless integration across multi‑vendor networks with a QSFP module that works with switches and routers supporting optics. Each unit is individually tested and validated prior to shipment, helping minimize deployment risk and ensure dependable operation within commercial temperature conditions.
