## Long description

The StarTech compatible SFP fiber optic transceiver for Cisco supports 1000BASE-SX multimode links at 1 GbE. This compact silver SFP module uses an LC connector and operates at an 850 nm wavelength, providing reliable fiber connectivity for multimode installations with a maximum reach of up to 550 m. The module supports digital diagnostic monitoring (DDM) and a 1.25 Gbit/s maximum data transfer rate while consuming less than 1 W of power, making it suitable for space-constrained network equipment and managed environments.
Advantages
This transceiver is programmed and tested for compatibility with Cisco switches and routers, offering a plug-and-play hot-swappable form factor that reduces downtime during upgrades or replacements. Built for multimode fiber links, it includes DDM for real-time monitoring of optical parameters and operates with low power consumption. The silver, compact SFP design simplifies installation into standard SFP slots and is covered by StarTech.com lifetime warranty and technical support.
Suitable for
1 Gbps multimode fibre uplinks between switches and access points
Data center server-to-switch connections over multimode fiber
Enterprise wiring closets and campus backbone links within 550 m
Field replacement or upgrade of SFP transceivers in compatible Cisco equipment

Typical weight and size: compact, lightweight silver module (~0.017 kg)
MTBF: 3,381,761 hours
How to use
Insert the SFP transceiver into an empty SFP port on a compatible Cisco switch or router until it clicks to secure the module. Connect an LC duplex multimode fiber cable (matching the module's 850 nm specification) between devices, ensuring correct transmit/receive orientation. The module is hot-swappable, so it can be inserted or removed while the host device is powered on; allow the device to recognise the transceiver and establish a link. Use the host equipment management interface to verify link status and view DDM readouts if required.
Usage recommendations
For optimal performance, use OM3/OM4 multimode fiber where possible and ensure fiber connectors are clean before connection. Match fiber type and patch-panel configurations to maintain the specified reach. Monitor DDM parameters periodically if the network requires proactive fault detection, and keep firmware and device compatibility lists up to date when deploying in Cisco equipment.
