Product information

Description

Dell SFP Module RK0CX-RFB 10Gb Multimode SR is an SFP+ optical transceiver engineered for short-reach fibre links. The module fits SFP+ slots in compatible Dell and third-party switches and servers, enabling 10 Gigabit Ethernet connections over multimode fiber (MMF). It is intended for LAN and data center interconnects where reliable, compact 10Gb connectivity is required. The small SFP+ form factor and multimode SR optics make it suitable for typical short-distance links within racks, between adjacent racks, or across short spans in enterprise networks.

Advantages

The RK0CX-RFB supports 10Gbps throughput in a compact SFP+ package and is optimized for multimode SR fibre, providing low-latency, high-bandwidth links for short distances. It is compatible with standard LC connectors and common multimode fibre types (OM1/OM2/OM3/OM4) as specified by the manufacturer, simplifying deployment in existing cabling infrastructures. The transceiver is designed for hot-swappable installation and integrates with network equipment that accepts SFP+ modules, facilitating upgrades or replacements without extended downtime.

Suitable for (tasks / use cases)

  • 10 Gigabit Ethernet connections inside data centres and server rooms
  • Short-reach links between switches, routers, and servers within a building or campus
  • Upgrading or replacing existing 10Gb multimode ports in compatible network equipment
  • High-bandwidth LAN interconnects and aggregation links

Key specifications

  • Manufacturer: Dell
  • Model / MPN: RK0CX-RFB
  • Form factor: SFP+ (hot-pluggable)
  • Data rate: 10 Gbps
  • Media type: Multimode fiber (MMF), SR optics
  • Connector type: Duplex LC

How to use

Ensure the target switch or server supports SFP+ transceivers and is compatible with third-party modules if applicable. Power down is generally not required because the module is hot-swappable; however, follow your equipment manufacturer’s hot-swap procedures. Insert the RK0CX-RFB into an available SFP+ slot until it latches, then connect duplex LC multimode fiber cables to the transmit and receive ports, observing proper polarity. Verify link status and speed through the device management interface or LED indicators. If the device requires specific configuration, consult the switch or server documentation to enable the 10Gb port.

Usage recommendations

Use high-quality multimode fiber (OM3 or OM4 recommended for best 10Gb performance over typical short-reach distances) and maintain correct cable polarity. Keep dust caps on connectors when not in use, inspect and clean fiber ends before mating, and follow ESD precautions when handling the transceiver to avoid damage. Verify firmware and compatibility notes for your network equipment to ensure optimal operation.
