Generic Compatible 800GBASE-SR8 OSFP IHS/Finned Top 8x100G PAM4 Broadcom DSP & VCSEL 850nm 100m OM4 MMF DOM MPO-16/APC Optical Transceiver Module

The Generic Compatible OSFP-800G-SR8 optical transceiver is an eight-channel parallel optical module designed for high-bandwidth 800G Ethernet connectivity in data center, cloud computing, and AI networking environments. Incorporating a Broadcom DSP and Broadcom VCSEL technology, it operates at a nominal wavelength of 850nm and supports an aggregate data rate of 800Gbps using 8x100G PAM4 optical lanes.

The module uses a single MPO-16/APC interface for bidirectional parallel multimode fiber transmission. It supports transmission distances of up to 60m over OM3 multimode fiber and up to 100m over OM4 multimode fiber, making it suitable for short-reach connections in high-density network environments. The APC connector interface is designed to provide controlled optical return loss when used with compatible MPO-16/APC fiber assemblies.

With its OSFP IHS/Finned Top housing, the transceiver is designed for compatible OSFP ports that require an appropriate thermal solution for high-speed optical modules. The finned housing provides additional surface area for heat dissipation, while actual thermal performance depends on host cage design, airflow, and system cooling conditions.

The OSFP-800G-SR8 provides a single 800G optical interface for direct connections between compatible 800G Ethernet ports. It can also support 2x400G SR4 breakout connectivity when used with a dedicated MPO-16-to-2xMPO-12 breakout fiber assembly and a host platform configured for the corresponding 400G breakout mode.

DDM functionality enables monitoring of supported module operating and optical parameters, helping network operators assess link status and troubleshoot connectivity issues. With a maximum power consumption of ≤14W, this module offers a high-density multimode optical connectivity solution for modern Ethernet switching infrastructure.

Highlights

Optimized for High-Density 800G Ethernet Networks

The OSFP-800G-SR8 is suitable for high-throughput network architectures that require compact, high-density optical connectivity. Typical deployment scenarios include:
  • 800G switch-to-switch connections in data center fabrics.
  • High-bandwidth links in AI training and GPU cluster networks.
  • Cloud data center spine-leaf switching architectures.
  • Short-reach connections between high-density Ethernet switches.
  • Network expansion in enterprise and hyperscale data centers.

Broadcom DSP and VCSEL Technology

The integration of Broadcom DSP and Broadcom VCSEL technology supports high-speed PAM4 signal processing and 850nm multimode optical transmission. This combination is designed for high-bandwidth short-reach Ethernet links where power efficiency, port density, and reliable signal transmission are important.

Single MPO-16 Interface for 800G Connectivity

Unlike twin-port 800G 2xSR4 modules that use two MPO-12 interfaces, the SR8 architecture consolidates eight 100G optical lanes into one MPO-16/APC interface. This simplifies the physical fiber connection for compatible native 800G links and provides a clear interface for dedicated 400G breakout cabling.

Flexible 2x400G SR4 Breakout Applications

When supported by the host platform, a dedicated MPO-16-to-2xMPO-12 breakout assembly can divide the 800G SR8 optical interface into two 400G SR4 links. This enables flexible connection designs for networks transitioning between 800G and 400G Ethernet ports. Correct fiber mapping, polarity, and host breakout configuration are essential.

Thermal Design for OSFP Switching Platforms

The IHS/Finned Top housing is intended for compatible OSFP cages and thermal configurations. Selecting the correct housing style helps ensure that the module fits the host platform’s mechanical and airflow requirements, particularly in densely populated switch systems.

Compatibility Testing and Deployment Support

Professional compatibility verification and optical/electrical parameter test reports are available to support integration into different network environments. DDM monitoring further assists network administrators with module diagnostics, link assessment, and routine maintenance.

Questions & Answers

OSFP-800G-SR8: Frequently Asked Questions

Q: Which is more cost-effective for switch interconnection: OSFP-800G-SR8 or OSFP-800G-2xSR4?

A: For direct 800G-to-800G switch interconnection, the OSFP-800G-SR8 uses a single MPO-16/APC fiber connection at each end, while the OSFP-800G-2xSR4 uses two MPO-12/APC connections. The SR8 solution can reduce the number of fiber connections and simplify cabling for compatible 800G links. However, the overall cost depends on the required fiber assemblies, host port configuration, and network topology.

Q: What is the main difference between OSFP-800G-SR8 and OSFP-800G-2xSR4?

A: The OSFP-800G-SR8 uses a single MPO-16/APC interface with eight 100G optical lanes to provide one 800GBASE-SR8 link. The OSFP-800G-2xSR4 uses two separate MPO-12/APC interfaces, each carrying an independent 400G SR4 optical channel. SR8 is typically used for direct 800G connections, while 2xSR4 provides two 400G optical links for supported breakout or dual-link configurations. The two designs are not directly interchangeable because their connector interfaces and lane mappings differ.

Q: Can this 800G SR8 module connect to two 400G SR4 modules?

A: Yes, a compatible 800G SR8 port can be broken out into two 400G SR4 links using a dedicated MPO-16-to-2×MPO-12 breakout fiber assembly, such as the specified NDD M4MPOAA2x8F cable. The cable must provide the correct fiber mapping and polarity for the SR8 and SR4 interfaces. Successful breakout also requires the host switch or system to support 2×400G port breakout and the corresponding lane configuration.

Q: What is the maximum transmission distance over OM3 and OM4 multimode fiber?

A: Based on the specified 800GBASE-SR8 reach, the module supports up to 60m over OM3 multimode fiber and up to 100m over OM4 multimode fiber. Actual reach depends on fiber quality, connector performance, insertion loss, and the complete link budget. Use OM4 fiber for applications requiring the full 100m reach.

Q: Can this OSFP-800G-SR8 module connect directly to an OSFP-800G-2xSR4 module?

A: No, not through a direct MPO-16-to-MPO-16 connection. The SR8 module uses a single MPO-16 interface, whereas the 2xSR4 module uses two MPO-12 interfaces. Interconnection requires a properly designed breakout or conversion fiber assembly with compatible lane mapping and polarity, and the host platforms must support the intended link configuration.
