200G QSFP56 SR4 Optical Transceiver: High-Speed, Monitor-Ready Solution for Data Center Connectivity​

In the era of big data, AI, and cloud computing, data centers demand transceivers that deliver ultra-fast speeds, reliable performance, and easy manageability. The 200G QSFP56 SR4 Optical Transceiver—equipped with an MPO-12 APC connector—rises to this challenge. It combines 200Gbps speed, real-time monitoring capabilities, and seamless installation, making it the ideal choice for short-to-medium distance high-speed networks that power modern digital operations.

Network downtime is costly, and proactive monitoring is key to avoiding disruptions—and this transceiver delivers with DDM (Digital Diagnostic Monitoring) support. DDM enables real-time tracking of critical operational parameters, including temperature, voltage, and optical power. For data center administrators, this means full visibility into the transceiver’s performance: they can spot potential issues (like abnormal temperature spikes or dropping optical power) early, troubleshoot remotely, and ensure the network runs at peak efficiency.

This level of control eliminates the guesswork from network maintenance, reduces the need for on-site inspections, and extends the transceiver’s lifespan by preventing damage from unmonitored stressors. It’s a game-changer for teams looking to minimize downtime and maximize network reliability.

At its core, the 200G QSFP56 SR4 Transceiver is built for speed and reach. It supports a blazing-fast 200Gbps data rate—enough to handle massive data transfers, real-time AI model training, and high-bandwidth cloud services that define modern data centers. Paired with KP4 forward error correction (FEC) and optimized for OM4 multimode fiber, it delivers reliable transmission over a maximum link length of 100m—the perfect range for short-to-medium distance connections, such as data center rack-to-rack, row-to-row, or switch-to-server links.

To ensure signal strength and integrity, the transceiver launches optical signals at an average power of -6.5~4dBm and boasts a receiver sensitivity of ＜-10.3dBm. These specs mean it maintains clear, consistent signals even at maximum reach, minimizing data loss and ensuring uninterrupted performance for mission-critical applications.

For busy data center teams, installation speed and connection reliability are non-negotiable—and this transceiver delivers on both fronts. It features an MPO-12 APC connector, a high-performance optical connector designed for secure, low-loss connections. The APC (Angled Physical Contact) design reduces back reflection, a common cause of signal interference, while the MPO-12 format supports 12 fiber strands in a single connector—ideal for the parallel optical architecture of 200GBASE-SR4.

Complementing the connector is the transceiver’s plug-and-play design and compact QSFP form factor. The QSFP form factor fits seamlessly into standard QSFP56 ports on switches, routers, and servers, while plug-and-play functionality eliminates the need for complex software configuration or firmware updates. Simply insert the transceiver into the port, and it’s ready to operate—cutting installation time and reducing the risk of human error.

Data centers are dynamic environments, with temperature fluctuations from equipment heat and cooling systems—and this transceiver is built to withstand them. It supports an operating temperature range of 0-70℃, making it suitable for deployment in both air-conditioned data center halls and semi-enclosed server racks. Whether facing the heat of peak computing hours or the cooler temperatures of off-peak periods, the transceiver maintains consistent performance, eliminating the need for specialized cooling solutions and ensuring year-round reliability.

While 200Gbps speed is essential, energy efficiency matters for reducing data center operational costs and carbon footprints. The 200G QSFP56 SR4 Transceiver has a max power consumption of 6W—a competitive figure for high-speed QSFP56 modules. This low-power design reduces energy bills (especially when deployed at scale, across hundreds of ports) and generates less heat, easing the load on data center cooling systems. It’s a “green" choice that lets businesses prioritize speed without sacrificing sustainability.

Compatibility with existing network equipment is critical for seamless upgrades—and this transceiver meets the SFF-8636 industry standard, a specification for QSFP transceivers that ensures interoperability with a wide range of networking gear. Whether your data center uses equipment from Cisco, HPE, Dell, or other leading brands, the transceiver integrates effortlessly, eliminating the need for proprietary hardware and simplifying mixed-vendor network upgrades. This compliance also means it’s backed by rigorous industry testing, guaranteeing consistent performance and reliability.
