SFP-transceivermodule EFB Elektronik SFP1000SX

The EFB Elektronik SFP1000SX is a Gigabit SFP transceiver module for multimode fiber networks. It supports a data rate of 1250 Mbit/s at an 850 nm wavelength and uses an LC connector. The module is compatible with standard MSA SFP ports and with many Cisco devices, providing reliable short-range fiber connectivity up to 550 m.

Advantages

The SFP1000SX offers standard-compliant performance for gigabit multimode links, compact SFP form factor for flexible port usage, and an LC connector for common fiber patching. Its compatibility with GLC-SX-SMD and MSA SFP ports enables easy replacement or upgrade in mixed-vendor networks.

Suitable for

• Short-range multimode fiber links within buildings or campuses
• Gigabit Ethernet connections between switches and servers
• Replacing or expanding SFP ports in network devices compatible with GLC-SX-SMD

Key specifications

• Data rate: 1250 Mbit/s
• Wavelength: 850 nm
• Maximum transfer distance: 550 m (multimode fiber)
• Connector type: LC
• Form factor: SFP (MSA compliant)
• Brand / MPN: EFB Elektronik / SFP1000SX

How to use

Insert the SFP1000SX module into a compatible SFP port on your switch, router or media converter until it seats securely. Connect LC-terminated multimode fiber patch cords to the module’s LC connector, observing transmit/receive orientation. After connecting, verify link status on the network device and configure interface settings (speed/duplex/auto-negotiation) if required by the host device.

Recommendations

Use multimode fiber rated for the intended distance and ensure clean LC connectors to maintain signal quality. Check device compatibility lists for GLC-SX-SMD or MSA SFP modules and monitor link LEDs or management interfaces after installation.
