Accortec 40GbE QSFP+ SR4 Short-Reach Optical Transceiver

The Accortec 40GbE QSFP+ SR4 Optical Transceiver is engineered to deliver exceptional performance for high-speed data transmission in modern networking environments. Designed for data centers and intra-building networks, this SR4 transceiver provides reliable, scalable connectivity that supports dense 40 Gigabit Ethernet deployments. With a QSFP+ form factor and an MPO/MTP parallel-optic interface, it enables plug-and-play integration into standard switch ports while reducing cabling complexity and rack space requirements. Built to meet industry standards, the Accortec SR4 module supports four parallel lanes and is optimized for short-reach multimode fiber, delivering consistent throughput for demanding workloads such as virtualization, storage networking, and high-performance computing.

Whether you’re upgrading an aging 10G backbone, building a new high-performance fabric, or consolidating traffic across server and storage layers, the Accortec 40GbE QSFP+ SR4 Optical Transceiver provides the speed, reliability, and flexibility required by modern networks. The SR4 designation denotes short-reach parallel optics, where four 10 Gbps lanes operate in parallel to achieve a total bandwidth of 40 Gbps. This design enables high-density port configurations without sacrificing signal integrity, making it an ideal choice for spine-leaf architectures, dense data-center racks, and campus networks that demand low latency and predictable performance. The module is designed for seamless interoperability with a wide range of 40G-enabled switches and routers, enabling a smooth upgrade path from older 10G deployments and enabling multi-vendor environments.

• High-capacity 40GbE QSFP+ SR4 solution: Four parallel 10 Gbps lanes deliver a total 40 Gbps data rate, enabling efficient uplinks and aggregation in crowded data centers. The SR4 optics use a multidielectric approach with a parallel optics design that optimizes cabling density and performance over short-reach multimode fiber, providing a compact, scalable solution for modern networks. This configuration supports tight-knit server-to-switch connections, high-performance storage access, and rapid data movement across multi-server clusters, all while keeping power consumption and physical footprint in check.

• Reliable performance for data centers and enterprise networks: Built to operate in demanding environments, this transceiver emphasizes consistent optical power delivery, accurate signal integrity across all four lanes, and robust link stability. The Accortec SR4 module helps maintain low error rates and stable throughput under typical data-center conditions, supporting busy I/O patterns common in virtualization, microservices, and database workloads. With a design focused on plug-and-play deployment, IT teams can reduce downtime during capacity upgrades and maintain high service levels for critical applications.

• MPO/MTP parallel fiber interface: The SR4 module uses a 12-fiber MPO/MTP connector to carry four 10 Gbps channels in parallel, delivering high throughput with a compact optical path. This arrangement minimizes cable clutter while preserving signal quality across all lanes. Compatible with standard OM3/OM4 multimode fiber, the transceiver supports straightforward fiber installation using widely adopted cabling choices, lowering long-term operating costs and simplifying maintenance in multi-vendor environments.

• Distance and fiber compatibility: SR4 short-reach optics are designed for intra-data center links, with typical reach up to 100 meters on OM3 fiber and up to 150 meters on OM4 fiber, depending on fiber quality and system margins. This makes the module ideal for server-to-switch uplinks, top-of-rack connections, and short-range inter-switch links within a single building or campus. The ability to operate across different multimode fibers provides flexibility when upgrading networks or deploying new data-center fabric topologies.

• Plug-and-play, hot-swappable and standardized form factor: The QSFP+ package aligns with industry-standard 40G Ethernet specifications, enabling simple installation and seamless upgrades in existing switch ports. The transceiver is designed for hot-swapping, reducing downtime during maintenance windows and facilitating rapid capacity expansions. With broad cross-vendor compatibility, it supports multi-vendor deployments and provides a reliable upgrade path as your network evolves.

How to install Accortec 40GbE QSFP+ SR4 Optical Transceiver

• Power down the networking device before handling the transceiver to minimize risk of electrical damage and to ensure a safe maintenance window.

• Inspect the QSFP+ slot and MPO/MTP fiber interface to verify compatibility with your switch or router. Ensure the fiber connectors and cables are clean and free of damage before installation.

• Insert the Accortec QSFP+ SR4 module into the appropriate QSFP+ slot until the latch engages securely. If the module does not seat properly, remove it and reinsert with proper alignment to avoid bent pins or improper contact.

• Connect the MPO/MTP fiber cables according to your network design. Maintain correct lane polarity and ensure proper Tx/Rx alignment across all four lanes. Use quality MPO/MTP cables and perform a basic fiber cleanliness check to prevent performance degradation.

• Power on the device and verify the link status on the switch port. Confirm that all four lanes are active and that the 40GbE link is established with expected throughput. If issues arise, re-seat the module, re-check fiber connections, and consult switch compatibility documentation for SR4 support.
