Description
The QFX‑QSFP‑40G‑SR4 is a high‑speed 40 GBASE‑SR4 QSFP+ optical transceiver designed for short‑range, high‑bandwidth connectivity in data center, campus core, and aggregation layer networks. It complies with the IEEE 802.3ba 40GBASE‑SR4 standard and the QSFP+ Multi‑Source Agreement (MSA), enabling reliable 40 Gbps Ethernet communication over multimode fiber (MMF).
Operating at 850 nm using parallel optics (4 lanes × 10 Gbps), this transceiver supports distances up to 100 m on OM3 and 150 m on OM4 multimode fiber using MTP/MPO‑12 connectors, making it ideal for short‑reach links such as Top‑of‑Rack (ToR) to aggregation, leaf to spine, and server interconnects. Its hot‑pluggable QSFP+ form factor enables quick installation or replacement without interrupting network operations.
Key Features:
• 40GBASE‑SR4 QSFP+ transceiver for up to 40 Gbps Ethernet over multimode fiber.
• Uses 4× 10 Gbps parallel optics at 850 nm wavelength for high‑speed transmission.
• Supports 100 m on OM3 and 150 m on OM4 multimode fiber (MTP/MPO‑12).
• Hot‑pluggable QSFP+ form factor allows easy deployment and serviceability.
• Ideal for data center short‑reach links, ToR uplinks, and fabric interconnects.
