Generic Compatible 400GBASE-2xSR4 OSFP IHS Finned Top 8x50G PAM4 850nm 100m MMF DOM Dual MPO-12/APC Optical Transceiver Module

The Generic Compatible 400GBASE-2xSR4 OSFP optical transceiver is a high-performance, dual-channel optical module designed for 400 Gigabit Ethernet connectivity in high-density data centers, cloud computing environments, and AI infrastructure. Featuring an OSFP form factor with an IHS/Finned Top thermal design, this module supports efficient heat dissipation and reliable operation in demanding high-speed networking environments.

Based on 8×50G PAM4 signaling, the 400GBASE-2xSR4 integrates two independent 200G SR4 optical channels, each consisting of four 50G PAM4 lanes. Operating at a nominal wavelength of 850nm, it supports transmission distances of up to 100 meters over OM4 multimode fiber (MMF). The dual MPO-12/APC optical interfaces provide independent connectivity for the two 200G channels, offering flexible deployment options for high-bandwidth optical interconnects.

Designed for short-reach, high-throughput data center applications, the OSFP-400G-2xSR4 is primarily deployed in compatible OSFP switch ports. Using suitable 12-fiber multimode MPO patch cables, such as M4MPOA12FB, it can establish two independent 200G optical connections to QSFP56 network interface cards (NICs). This architecture enables connectivity between 800G OSFP switching platforms and multiple 200G server network adapters, supporting efficient network breakout and high-density server interconnection.

Compliant with OSFP MSA, IEEE 802.3cm, and CMIS 5.2 standards, the module supports hot-pluggable operation and Digital Diagnostic Monitoring (DDM), allowing real-time monitoring of key operating parameters. With a maximum power consumption of ≤14W and an integrated IHS/Finned Top cooling structure, it is engineered to meet the thermal and operational requirements of high-performance switching systems.

The Generic Compatible 400GBASE-2xSR4 OSFP transceiver provides a flexible and cost-effective solution for upgrading data center connectivity, improving network scalability, and building high-bandwidth optical interconnection architectures.

OSFP-400G-2xSR4: Frequently Asked Questions

Q: Why does the OSFP-400G-2xSR4 use MPO-12/APC connectors instead of standard PC connectors?

A: The module uses MPO-12/APC connectors to provide reliable multi-fiber connectivity while minimizing optical back reflections. The 8° angled physical contact (APC) end face reduces reflected optical power, helping improve optical link stability and signal integrity. Properly matched MPO-12/APC fiber patch cables are required for optimal performance.

Q: Which mainstream networking platforms are compatible with the OSFP-400G-2xSR4?

A: This module is designed for compatible OSFP-based 400G/800G switching platforms, including systems based on Broadcom Tomahawk 5 and NVIDIA Spectrum-X architectures, as well as selected Arista 7060 and 7050X series switches. Actual compatibility depends on the switch model, port configuration, firmware, and transceiver qualification requirements. Contact our technical team for a compatibility check before ordering.

Q: What are the typical applications of the OSFP-400G-2xSR4 optical transceiver?

A: The OSFP-400G-2xSR4 is designed for high-bandwidth short-reach interconnects in data centers and AI infrastructure. It is typically deployed in OSFP switch ports and provides two independent 200G SR4 optical links through dual MPO-12/APC interfaces. With compatible multimode fiber patch cables, such as M4MPOA12FB, it can connect an 800G OSFP switch to two 200G QSFP56 NICs, enabling efficient connectivity between high-performance switching infrastructure and server network adapters. The switch port must support the required 400G operating configuration.

Q: Can the two 200G SR4 channels operate independently?

A: Yes. The OSFP-400G-2xSR4 integrates two independent 200G SR4 optical engines, each supporting four 50G PAM4 lanes. Each optical engine has its own MPO-12/APC interface and can connect to a separate 200G QSFP56 device. This dual-channel architecture provides flexible connectivity for breakout applications and high-density data center networks, subject to host port configuration and system support.

Q: Can the OSFP-400G-2xSR4 interoperate with standard 400G SR4 optical transceivers?

A: No, not as a direct optical link. The OSFP-400G-2xSR4 uses two independent 200G SR4 channels, each with 4×50G PAM4 lanes, while conventional 400G SR4 modules, such as OSFP-400G-SR4, QSFP112-400G-SR4, and QSFP-DD-400G-SR4, typically use a single 400G optical interface with 4×100G PAM4 lanes. Their optical lane configurations and modulation rates are different, making them incompatible for direct optical interconnection. A suitable architecture requires matching transceiver types and supported host configurations at both ends.
