25Gbps SFP28 Connectivity

The SFP-25G-LR-S is designed for 25GbE networking applications. SFP28 is the enhanced successor to the SFP+ form factor and is specifically designed to support 25Gb/s-class applications. Broadcom identifies SFP28 as a form factor targeting 25Gb/s to 28Gb/s applications, including 25GbE. :contentReference[oaicite:3]{index=3}

With 25Gbps bandwidth, the transceiver is suitable for high-throughput server connectivity, storage networking, data-center aggregation and network interconnects.

10km Long-Range Transmission

The LR designation indicates Long Reach operation. The SFP-25G-LR-S class provides up to 10km of transmission over compatible Single-Mode Fiber.

This reach makes the transceiver suitable for longer fiber runs between data-center equipment, buildings, network aggregation points and enterprise facilities.

1310nm Optical Wavelength

The module operates at approximately 1310nm. This wavelength is commonly used for long-distance single-mode Ethernet transmission.

25GBASE-LR references specify 1310nm operation over Single-Mode Fiber for links up to 10km. :contentReference[oaicite:4]{index=4}

Single-Mode Fiber Support

The SFP-25G-LR-S is designed for Single-Mode Fiber (SMF). For best results, use compatible 9/125µm single-mode fiber cabling and appropriate duplex LC connectors.

Single-mode fiber provides the optical characteristics required for long-distance 25GbE transmission and is significantly better suited to 10km links than standard multimode fiber.

Duplex LC Connector

The transceiver uses a Duplex LC optical interface. One fiber is used for transmission and the other for reception, providing full-duplex communication.

Ensure that the installed patch cords and fiber infrastructure use compatible LC connectors and single-mode fiber.

DFB Laser Transmitter

25GBASE-LR SFP28 modules commonly use a 1310nm DFB laser transmitter for long-distance single-mode transmission. Broadcom-compatible LR references identify DFB transmission and PIN reception for this class of module. :contentReference[oaicite:5]{index=5}

PIN Receiver

The receiver uses a PIN photodiode to convert incoming optical signals into electrical signals. This optical architecture is commonly used in 25GBASE-LR modules.

Digital Diagnostic Monitoring

Broadcom-compatible SFP-25G-LR-S references support Digital Diagnostic Monitoring (DDM/DOM). This allows compatible networking equipment to monitor parameters such as optical transmit and receive power, temperature and module operating conditions. :contentReference[oaicite:6]{index=6}

DDM availability and the specific diagnostic values exposed to the host system depend on the transceiver implementation and the network equipment.

Data Center Applications

The Broadcom SFP-25G-LR-S is well suited to modern data-center networking environments where 25GbE connectivity and longer optical reach are required.

• 25GbE server-to-switch connections
• Data-center interconnects
• Leaf-and-spine networks
• Enterprise campus networks
• High-performance computing networks
• Storage network infrastructure
• Network aggregation
• Server NIC connectivity
• Long-distance switch uplinks
• Inter-building fiber connections

Broadcom SFP28 Compatibility

Broadcom's SFP28 ecosystem supports a range of optical transceivers for its 25G networking products. A current Broadcom-compatible transceiver support document lists 25GBASE-LR SFP28 optics for Broadcom 25G NICs, including Broadcom BCM957414A4142CC and BCM957504-P425G platforms. :contentReference[oaicite:7]{index=7}

Actual interoperability depends on the exact NIC, switch, firmware and transceiver coding. Always confirm the supported optics list for the target Broadcom device before deployment.

Long-Distance 25GbE Networking

The 10km reach of the SFP-25G-LR-S provides significantly greater fiber distance than SR-class 25G optics. For example, Cisco's 25G optical specifications list 25GBASE-SR for approximately 70m on OM3 and 100m on OM4/OM5, while its 25G LR-S class reaches 10km over SMF. :contentReference[oaicite:8]{index=8}

This makes LR optics the appropriate choice when a 25GbE connection needs to travel well beyond typical data-center multimode distances.

Power and Thermal Considerations

25G SFP28 optical modules are designed for relatively low-power operation compared with larger QSFP-class modules. Exact power consumption depends on the specific Broadcom module implementation.

For standard commercial-temperature deployments, compatible 25GBASE-LR SFP28 references commonly specify an operating range of 0°C to 70°C. :contentReference[oaicite:9]{index=9}

Installation Considerations

• Use compatible 25GbE SFP28 ports.
• Use Single-Mode Fiber for LR operation.
• Use compatible duplex LC connectors.
• Confirm the host switch or NIC supports the transceiver.
• Check transceiver coding and vendor compatibility.
• Clean fiber connectors before installation.
• Verify optical power levels and link budget for long fiber runs.

Optical modules should always be installed according to the host equipment manufacturer's compatibility requirements. A physically compatible SFP28 module is not necessarily supported by every switch or NIC.
