Questions & Answers

QSFP112-400G-VR4: Frequently Asked Questions

Q: What is the maximum transmission distance of the QSFP112-400G-VR4 optical transceiver?

A: The QSFP112-400G-VR4 supports transmission distances of up to 50 meters over OM4 multimode fiber, subject to the specified fiber type and link conditions.

Q: What are the differences between the QSFP112-400G-SR4 and QSFP112-400G-VR4?

A: Both the QSFP112-400G-SR4 and QSFP112-400G-VR4 are 400G multimode optical transceivers featuring the QSFP112 form factor and an MPO-12 optical interface. The primary difference is the specified transmission distance. The QSFP112-400G-VR4 supports up to 50 meters over OM4 fiber, while the QSFP112-400G-SR4 may support up to 100 meters, depending on the product specifications. The two modules may interoperate over links of up to 50 meters when their optical specifications, connector configuration, and fiber requirements are compatible.

Q: Can a QSFP112-400G-VR4 module be installed in an OSFP port?

A: No. QSFP112 and OSFP are different physical form factors, so a QSFP112-400G-VR4 module cannot be directly installed in an OSFP port. To connect equipment using these two form factors, use compatible transceivers at each end and an optical fiber link that meets the requirements of both modules.

Q: Can a QSFP-DD 400G SR4 module interoperate with a QSFP112 400G SR4/VR4 or OSFP 400G SR4 module?

A: Yes, optical interconnection may be possible when both modules support compatible optical specifications, including wavelength, lane mapping, fiber type, and connector configuration. QSFP-DD, QSFP112, and OSFP identify different physical form factors and do not, by themselves, guarantee interoperability. Verify the specifications of the exact modules and host platforms before deployment.

Q: Are QSFP112 ports backward compatible with legacy QSFP modules?

A: QSFP112 ports are not universally backward compatible with legacy QSFP modules. Support for 40G, 100G, or 200G modules and cables depends on the host platform, supported data rates, electrical interface, and system configuration. Check the equipment manufacturer’s compatibility documentation before using legacy modules or cables.
