Description

Finisar 40GBASE-SR4/10GBASE-SR 300m Gen3 QSFP+ Optical Transceiver

The Finisar 40GBASE-SR4/10GBASE-SR 300m Gen3 QSFP+ Optical Transceiver is engineered for high-density data centers and enterprise networks that demand flexible, multi-rate fiber connectivity. This Gen3 QSFP+ module delivers reliable performance for both 40 Gigabit Ethernet and 10 Gigabit Ethernet applications, enabling seamless uplinks, spine-leaf architectures, and return-path scalability. Designed to operate over multi-mode fiber with a reach of up to 300 meters, it’s a versatile solution that reduces cabling complexity while preserving throughput and efficiency. With its hot-pluggable form factor and broad operating temperature range, this transceiver is built to simplify deployment in crowded racks, crowded data centers, and mixed hardware environments. Whether you are upgrading from 10G to 40G or deploying a new 40G backbone, this transceiver provides the robust, standards-compliant performance you need for data networking and fiber channel interconnects.

  • Flexible multi-rate performance in a single QSFP+ package: supports 40GBASE-SR4 for Ethernet and 10GBASE-SR for legacy or mixed deployments, enabling a smooth transition path and optimized port utilization in dense network environments.
  • Dense MPO-based multi-fiber interface for high-density deployments: designed around an MPO duplex fiber channel network interface that consolidates lanes, reduces physical footprint, and minimizes rack cabling while preserving full lane performance.
  • Impressive reach on standard multi-mode fiber: delivers up to 300 meters of link distance on common MMF cabling, making it ideal for data center top-of-rack, aggregation, and spine layers without costly fiber upgrades or rewiring.
  • Hot-pluggable QSFP+ form factor with robust, commercial-grade operability: easy to insert and remove from compatible switches and routers, supporting maintenance windows and minimizing downtime in live networks; operable over a broad temperature range (0°C to 70°C) for reliability in data centers and IT closets.
  • Broad compatibility with data center and enterprise networks: optimized for 40GBASE-SR4 and 10GBASE-SR optics across Fibre Channel and Ethernet contexts, enabling flexible uplinks, storage fabrics, and virtualization-ready architectures in modern IT environments.

Technical Details of Finisar 40GBASE-SR4/10GBASE-SR 300m Gen3 QSFP+ Optical Transceiver

  • Interface: 1 x MPO Duplex Fiber Channel Network interface, designed to support multi-fiber connectivity for SR4 applications on multi-mode fiber.
  • Data Rates: 40GBASE-SR4 and 10GBASE-SR, enabling simultaneous support for high-speed 40G Ethernet links and compatible 10G links as required by network architecture or downtime considerations.
  • Fiber Type: Multi-mode fiber (MMF), compatible with common MMF installations found in data centers and corporate networks.
  • Reach: 300 meters on standard multi-mode fiber cabling, offering a practical balance between distance and cabling cost for mid-range to large deployments.
  • Connector Type: MPO (Multi-Fiber Push On) interface aligned with SR4 specifications for high-bandwidth lane aggregation and reliable, multi-lane signaling.
  • Temperature Range: Commercial operating range from 0°C to 70°C, suitable for typical data center environments and IT closets without additional cooling.
  • Hot-Plug Capability: Yes, designed to be inserted and removed without powering down the host equipment (where supported by the system), reducing downtime during upgrades and maintenance.
  • Compliance and Emulation: Designed to support industry-standard SR4 and SR optics for interoperability with a wide array of switches, routers, and storage fabrics in mixed-vendor environments.

how to install Finisar 40GBASE-SR4/10GBASE-SR 300m Gen3 QSFP+ Optical Transceiver

  • Prepare the system: Confirm that your chassis, switch, or server has a compatible QSFP+ slot and supports 40GBASE-SR4 and/or 10GBASE-SR optics. Power down the device if required by your maintenance policy, and ground yourself to prevent electrostatic discharge.
  • Handle with care: Keep the transceiver in its protective package until you’re ready to install. Avoid touching the optical interface and connector ferrules to prevent contamination and maintain optimal signal integrity.
  • Insert the transceiver: Align the QSFP+ module with the slot and slide it straight into the port until it clicks securely into place. Do not apply excessive force; if resistance is felt, remove and reinsert gently to ensure proper seating.
  • Connect the fiber cabling: Attach the MMF cable to the MPO connector as specified by your network design. Ensure correct fiber orientation and lane mapping to match the target interfaces, and verify that the connectors are clean and free of dust or debris.
  • Power up and validate: Restore power to the device and check the link status indicators or management software to confirm that the transceiver is recognized and that link negotiation is successful. Test traffic flow and monitor error counters to verify stability across both 40G and 10G lanes as needed.
