Generic Compatible 400GBASE-SR8 QSFP112 4x100G PAM4 850nm 100m MMF DOM MPO-16/APC Optical Transceiver Module

The QSFP112-400G-SR8 optical transceiver is a high-performance 400G optical module designed for high-bandwidth Ethernet connectivity in AI data centers and next-generation data center networks. Featuring a QSFP112 form factor, it supports a 400Gbps aggregate data rate with four 100G PAM4 electrical lanes and eight 50G optical lanes. Operating at a nominal wavelength of 850nm, this 400G QSFP112 SR8 module supports transmission distances of up to 100 meters over OM4 multimode fiber using an MPO-16/APC connector. Designed for low power consumption, low latency, and high port density, it is suitable for high-performance computing (HPC), AI data center (AIDC), and data center network (DCN) applications. The module is designed to comply with IEEE 802.3db, QSFP112 MSA, and applicable CMIS specifications, supporting high-speed optical connectivity in compatible 400G network infrastructures.

The QSFP112-400G-SR8 optical transceiver can be deployed in compatible 400G Ethernet environments to connect QSFP112-equipped network interface cards (NICs) with QSFP-DD-based switches or other supported 400G network devices. Successful interoperability depends on the host port configuration, optical specifications, fiber polarity, and device compatibility. With its eight-lane multimode optical interface and high-density QSFP112 design, this module provides a practical connectivity solution for bandwidth-intensive AI workloads and scalable data center networks.

Questions & Answers

QSFP112-400G-SR8: Frequently Asked Questions

Q: What modulation scheme does the QSFP112-400G-SR8 optical transceiver use?

A: The QSFP112-400G-SR8 optical transceiver supports eight 50Gbps PAM4 optical lanes, delivering an aggregate data rate of 400Gbps. “SR” stands for Short Reach, indicating short-distance optical transmission, while “8” refers to the eight optical lanes used by the module.

Q: What are the connectivity options for the 400G QSFP112 SR8 transceiver?

A: The 400G QSFP112 SR8 supports direct 400G connections between compatible SR8 optical transceivers using an appropriate multimode fiber link. For breakout applications, a compatible 400G SR8 interface can potentially connect to two 200G QSFP56 SR4 transceivers using a suitable MPO-16 to 2xMPO-8 multimode breakout harness. The host ports, optical lane mapping, connector polarity, and breakout configuration must all be supported by the connected equipment.

Q: Can QSFP112-400G-SR4 and QSFP112-400G-SR8 optical transceivers be interconnected?

A: Not directly in a standard optical link configuration. The SR4 and SR8 modules use different optical lane configurations and connector interfaces. A typical 400G SR4 module uses an MPO-12 connector with four 100G optical lanes, whereas a 400G SR8 module uses an MPO-16 connector with eight 50G optical lanes. Direct interconnection is therefore not supported by default. Any alternative connection would require specifically compatible optical interfaces and a supported lane-mapping solution.

Q: Can a QSFP112-400G-SR8 module interoperate with an OSFP-400G-SR8 or QSFP-DD-400G-SR8 module?

A: Yes, interoperability is possible when both modules support compatible 400G SR8 optical specifications, including wavelength, optical lane configuration, and transmission requirements. QSFP112, OSFP, and QSFP-DD identify different module form factors, so each transceiver must match its host port. A suitable MPO-16 multimode fiber assembly with the correct connector type and polarity is also required. Verify the specifications of both modules and host devices before deployment.
