It is particularly suitable for AI training clusters, GPU computing platforms, RoCE networks, and HPC infrastructure that require high-bandwidth, low-latency connectivity over multimode fiber.

Q: What advantages does the Q112-200G-VR2 offer for AI data center networks?

A: It provides a compact 200G optical connectivity option for GPU servers and high-density switching platforms. Its short-reach multimode architecture supports efficient in-rack and adjacent-rack connections, while its QSFP112 form factor helps optimize front-panel port density. When deployed with compatible host interfaces and supported configurations, it can help simplify 200G server connectivity within 400G/800G data center fabrics.

Q: Why is the delivered module labeled Q112-400G-VR4 when I ordered a 200G VR2 transceiver?

A: This product is based on the Q112-400G-VR4 hardware platform and is configured to operate in a 200G VR2 mode. Therefore, the physical module may carry a Q112-400G-VR4 model label even when supplied for a 200G application. Before deployment, verify that the module firmware, operating mode, and host port configuration support the intended 200G operation. Its compatibility and performance should be evaluated against the specified 200G operating requirements rather than assumed to be identical to every native 200G VR2 implementation.

Q: Can the Q112-200G-VR2 connect to a 400G Ethernet switch?

A: Yes, provided the switch supports the required port breakout or 200G operating mode and the corresponding optical module configuration. A compatible 400G switch port may be configured to provide 200G connectivity, depending on the switch hardware, port capabilities, and software configuration. Always confirm the supported breakout options and interface settings with the switch vendor before deployment.

Q: What fiber patch cable is required for the Q112-200G-VR2?

A: The module uses a single MPO-12/APC optical interface and is designed for multimode fiber connectivity. Use an MPO-12/APC multimode patch cable compatible with the module’s connector gender, fiber type, and polarity requirements. OM4 multimode fiber supports the specified link distance of up to 50m. Before ordering a patch cable, verify its MPO end-face polish, pin configuration, polarity, and fiber grade against the module and the connected equipment.

Q: What is the maximum transmission distance of the Q112-200G-VR2?

A: The Q112-200G-VR2 supports link distances of up to 50m over OM4 multimode fiber under the specified operating conditions. Actual link performance depends on fiber quality, connector cleanliness, cable polarity, and the optical specifications of the connected devices.
