50Gbps SFP56 Connectivity

The R0M48A provides a 50Gbps optical connection using the SFP56 form factor. SFP56 is designed for high-bandwidth networking applications while maintaining a compact transceiver footprint.

HPE Aruba documentation describes 50G SFP56 technology as a single-lane serial PAM4 solution delivering 50Gbps. The technology uses LC connectors for compatible optical modules. :contentReference[oaicite:4]{index=4}

850nm SR Optics

The R0M48A uses a nominal 850nm wavelength and SR optical technology. This makes the transceiver suitable for short-distance multimode-fiber connections.

Because SR optics are designed for short-range connectivity, they are well suited to data center environments where switches and servers are located within the same rack, adjacent racks or nearby network distribution areas.

Multimode Fiber Support

The R0M48A is designed for multimode fiber (MMF) using a duplex LC connection.

HPE specifies a 50/125µm fiber diameter for the R0M48A. OM3 fiber supports up to 70 meters, while OM4 and OM5 multimode fiber support up to 100 meters. :contentReference[oaicite:5]{index=5}

100m Maximum Transmission Distance

The R0M48A is commonly marketed as a 100m 50G SR transceiver. The 100-meter maximum applies when the module is used with OM4 or OM5 multimode fiber.

HPE specifically notes that 50G SR transceivers are not supported over OM1/OM2-quality multimode fiber because the relevant IEEE standard does not specify requirements for those fiber types. :contentReference[oaicite:6]{index=6}

50G PAM4 Technology

The R0M48A uses 1x 50G PAM4 signaling. PAM4 allows the module to achieve 50Gbps transmission using a single optical lane.

The R0M48A is therefore different from a 100G QSFP28 SR4 module, which uses a different form factor and optical architecture.

Duplex LC Connector

The R0M48A uses a duplex LC optical connector. Two fiber strands are used for the bidirectional connection, with one strand carrying transmit traffic and the other carrying receive traffic.

Use compatible multimode LC fiber patch cables and ensure that the fiber grade is appropriate for the required transmission distance.

Tri-Speed Capability

One of the important characteristics of R0M48A is its tri-speed capability. HPE Aruba documentation identifies the module as capable of operating at 10G, 25G and 50G under supported configurations. :contentReference[oaicite:7]{index=7}

However, the remote interface and switch port must support the required speed. HPE notes that 50G SR, eSR and LR transceivers do not automatically detect the remote speed; the speed must be configured on the interface hosting the transceiver when connecting to a supported 10G or 25G remote optic. :contentReference[oaicite:8]{index=8}

Digital Optical Monitoring

The R0M48A supports Digital Optical Monitoring (DOM). DOM can provide optical module diagnostic information that helps network administrators monitor transceiver operating conditions.

This feature can be useful for troubleshooting optical links and identifying abnormal operating conditions in supported HPE Aruba switch environments.

Optical Power Specifications

HPE Aruba documentation specifies R0M48A transmit power from -6 to +4 dBm and receive power from -8.4 to +4.0 dBm. The specified operating temperature is 0°C to 70°C and required power is 1.5W. :contentReference[oaicite:9]{index=9}

Compatible HPE Aruba Networking Switches

HPE Aruba documentation lists R0M48A among the supported 50G SFP56 transceivers for compatible Aruba networking platforms.

For example, HPE's transceiver documentation lists R0M48A for the Aruba 6300 Switch Series, subject to the applicable hardware model and minimum AOS-CX software version. :contentReference[oaicite:10]{index=10}

The R0M48A is also listed among the supported SFP56 transceivers for the HPE Aruba Networking CX 6400 platform. :contentReference[oaicite:11]{index=11}

Exact compatibility depends on the switch model, port type, software version and configuration. Always check the HPE Aruba transceiver compatibility guide for the target switch before deployment.

Data Center Networking

The R0M48A is well suited to short-range data center networking. Its 50Gbps bandwidth can be used for high-speed switch interconnects, server connectivity, aggregation and other bandwidth-intensive network applications.

OM4 and OM5 multimode fiber allow the full 100-meter specified reach, providing enough distance for many rack-to-rack and row-level data center deployments.

Enterprise Network Infrastructure

Organizations upgrading network infrastructure from 10GbE or 25GbE can use compatible 50G SFP56 platforms to increase available bandwidth while maintaining a compact transceiver form factor.

The tri-speed capability of R0M48A can provide additional flexibility in supported Aruba environments where 10G, 25G and 50G connectivity are required. :contentReference[oaicite:12]{index=12}

R0M48A vs 50G LR SFP56

Compatibility Considerations

The R0M48A is an SFP56 transceiver and must be installed in a compatible 50G-capable port. Although the physical module size is similar to other SFP-family products, a port must support the required 50G capability.

HPE Aruba specifically notes that 50G products only work in ports capable of 50G speeds, usually marked as SFP56. Tri-speed transceivers such as R0M48A provide additional 10G/25G/50G functionality only in supported configurations. :contentReference[oaicite:13]{index=13}
