Cisco Transceiver module network transceiver module

The Cisco Transceiver module network transceiver module is a hot-swappable SFP (Small Form-factor Pluggable) gigabit interface converter designed for use in Gigabit Ethernet ports and slots. Conforming to the IEEE 802.3z 1000BASE-SX standard, this module supports multimode fiber links and enables fiber connectivity for compatible network devices. The module's compact SFP form factor allows flexible deployment in switches, routers and network interface cards that accept SFP transceivers.

Advantages

This 1000BASE-SX transceiver provides standardized gigabit fiber connectivity in a hot-pluggable SFP package, enabling easy upgrades or replacements without powering down equipment. It supports short-range multimode fiber runs and is backward-compatible with equipment that adheres to IEEE 802.3z specifications. The module's small size and industry-standard interface simplify inventory and interoperability across a range of network hardware.

Suitable for

• Short-range multimode fiber connections in data centers and campus networks
• Upgrading or replacing SFP ports on switches, routers and media converters
• Linking Gigabit Ethernet devices over multimode fiber within buildings or between nearby facilities

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Standard: IEEE 802.3z 1000BASE-SX
• Fiber type: Multimode fiber
• Distance: Up to 550 m on 50 µm multimode fiber; up to 220 m on 62.5 µm FDDI-grade multimode fiber
• Weight: 0.075 kg

How to use

Insert the SFP transceiver into an SFP port until it seats firmly and the latch engages; follow the host device manufacturer's guidance for hot-plugging to avoid interrupting traffic. Connect the multimode fiber cable (with the appropriate connector type) to the transceiver's fiber port, ensuring correct polarity and secure connections. Verify link and activity LEDs on the host device to confirm successful link negotiation at gigabit speed.

Recommendations

Use multimode fiber of the correct core size for the specified distances: 50 µm fiber for runs up to 550 m and 62.5 µm FDDI-grade fiber for runs up to 220 m. Handle the transceiver and fiber connectors with care to avoid contamination; inspect and, if necessary, clean connector endfaces before mating. Replace or upgrade SFP modules in accordance with your network maintenance procedures and compatibility requirements.
