50Gbps High-Speed Connectivity

The R0M48A provides 50Gbps optical connectivity using the SFP56 form factor. This enables high-bandwidth network links for modern data center and enterprise Ethernet infrastructure.

50G SFP56 technology uses a single-lane PAM4 architecture. HPE notes that 50G SFP56 technology cannot be split into two independent 25G flows; it is a single-lane, single-wavelength technology. :contentReference[oaicite:4]{index=4}

850nm SR Optics

The R0M48A uses an 850nm optical wavelength and SR short-range multimode fiber technology. This makes it appropriate for short-distance data center links where multimode fiber infrastructure is already deployed.

The transceiver uses duplex LC connectivity and is designed for 50/125µm multimode fiber. :contentReference[oaicite:5]{index=5}

OM3, OM4 and OM5 Fiber Support

HPE specifies the R0M48A for multimode fiber with different maximum distances depending on the fiber grade.

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

Tri-Speed 10G / 25G / 50G Capability

The R0M48A is a tri-speed capable transceiver supporting 10Gbps, 25Gbps and 50Gbps operation on compatible platforms. HPE lists the R0M48A as tri-speed capable in its transceiver documentation. :contentReference[oaicite:7]{index=7}

When using 50G SR optics in a lower-speed link, the host interface and network configuration must support the selected operating speed.

Duplex LC Connector

The R0M48A uses a duplex LC connector for multimode fiber connectivity. A duplex LC connection uses separate optical paths for transmit and receive.

Use compatible LC-terminated OM3, OM4 or OM5 multimode fiber cabling for the specified link distances.

Digital Optical Monitoring

The R0M48A supports Digital Optical Monitoring (DOM). HPE's transceiver guide identifies DOM as supported for the R0M48A. :contentReference[oaicite:8]{index=8}

DOM can provide optical diagnostic information such as operating parameters and optical levels when the host switch platform supports and exposes the relevant monitoring functions.

Optical Performance

HPE specifies transmit power of approximately -6 to +4 dBm and receive power of approximately -8.4 to +4.0 dBm for the R0M48A. :contentReference[oaicite:9]{index=9}

These optical specifications are useful when designing and troubleshooting compatible 50G multimode fiber links.

Power and Temperature

The R0M48A is specified for a commercial operating temperature range of 0°C to 70°C and a required power rating of 1.5W. :contentReference[oaicite:10]{index=10}

Ensure that the host switch provides an SFP56 port and supports the required thermal and power characteristics before deployment.

HPE Aruba Networking Compatibility

HPE documents R0M48A compatibility across selected Aruba networking platforms. The Aruba 6300 Switch Series supports R0M48A on compatible SFP56 ports with the required software versions. :contentReference[oaicite:11]{index=11}

HPE also lists R0M48A among the supported SFP56 transceivers for Aruba 6400 modules and selected 6300L platforms. :contentReference[oaicite:12]{index=12}

Compatibility varies by exact switch model, port configuration and software release. Always verify the host device's current HPE compatibility documentation before installation.

Data Center Networking

The R0M48A is well suited to short-distance 50Gbps data center links. It can be deployed in compatible SFP56 ports for switch-to-switch connectivity, server connectivity and high-bandwidth network infrastructure.

Its multimode SR architecture is particularly useful in environments where OM3, OM4 or OM5 structured fiber cabling is already installed.

HPE R0M48A vs 50G LR Transceiver

Compatibility Considerations

The R0M48A is an SFP56 optical transceiver and requires a compatible SFP56 host port. It should not be assumed to work in every SFP+ or SFP28 port simply because those form factors are physically related.

• Compatible SFP56 port
• Supported HPE Aruba Networking switch
• Compatible switch software/firmware
• OM3, OM4 or OM5 multimode fiber
• Duplex LC fiber connection
• Appropriate 50G interface configuration

HPE's compatibility documentation should be checked for the exact switch SKU and software release before deployment. :contentReference[oaicite:13]{index=13}
