Product information

Description

The StarTech EX-SFP-1GE-SX is a compatible SFP fiber transceiver module designed for 1000BASE-SX networks. It provides reliable 1 Gbps connectivity over multimode fiber using an LC connector and operates at an 850 nm wavelength with a maximum reach of 550 m (1804 ft). The module supports Digital Diagnostics Monitoring (DDM), has low power consumption (under 1 W) and a high MTBF to support sustained network operation.

Advantages

This EX-SFP-1GE-SX module is hot-swappable for easy installation and replacement without prolonged network downtime. It is compatible with Juniper® switches and routers when used as an EX-SFP-1GE-SX equivalent, offers a compact SFP form factor for flexible deployment, and includes lifetime warranty and multilingual technical support from StarTech.com.

Suitable for

1000BASE-SX multimode fiber links
Local area network uplinks and switch-to-switch connections
Short-to-medium distance fiber connections up to 550 m
Maintenance and replacement of SFP ports in Juniper-compatible equipment

How to use

Power down the SFP port or, if supported, insert the EX-SFP-1GE-SX module into an active SFP slot while the device remains powered (hot-swappable). Connect LC-terminated multimode fiber cables to the module, ensuring correct polarity. Configure the switch or router interface for 1000BASE-SX operation if necessary and verify link status and DDM readings via the device management interface.

Usage recommendations

Use multimode fiber rated for 850 nm and keep fiber connectors clean to maintain optimal signal quality. For runs approaching the 550 m limit, verify fiber type and modal bandwidth to ensure reliable performance. Keep firmware and device drivers up to date and consult StarTech.com support for compatibility questions.
