SFP Transceiver Module StarTech GLC-SX-MM (10 Pack) — 1000BASE-SX, 1GbE Multimode, LC, 850nm, 550m

The StarTech GLC-SX-MM SFP Transceiver Module (10 Pack) provides 1000BASE-SX Gigabit Ethernet connectivity over multimode fiber in a compact SFP form factor. Each module operates at an 850 nm wavelength with an LC duplex interface and supports a maximum link distance of up to 550 m. Housed in a metal zinc-steel enclosure, these hot-swappable transceivers are designed for use with compatible switches and routers to deliver reliable 1 GbE links for data, storage and network aggregation applications.

Advantages

These modules offer standardized 1 GbE multimode fiber performance with an LC connector and low typical power consumption (around 1 W) in a durable metal housing. The ten-pack format simplifies large deployments and spares management, while the compact SFP form factor enables broad compatibility with SFP ports on enterprise switches and routers. Digital diagnostics monitoring support and thorough testing for compatibility provide predictable operation and easier maintenance.

Suitable for

• Connecting aggregation switches and access switches within campus or data center environments
• Short- to medium-range fiber links between buildings or equipment racks
• Replacing or stocking spare SFP modules for network infrastructure maintenance
• Deployments requiring LC-terminated multimode fiber at 850 nm

How to use

Install each SFP transceiver into an empty SFP port on a compatible switch or router until it clicks into place. Connect LC-terminated multimode fiber patch cables to the transceiver’s duplex LC interface, observing correct Tx/Rx orientation. After insertion and cable connection the device and link should negotiate to 1 GbE where supported; no additional configuration is typically required on standard network equipment. For replacements or upgrades, remove the existing module while the port is unused or consult your equipment vendor’s hot-swap guidance to minimize disruption.

Usage recommendations

Use multimode fiber rated for 850 nm operation and appropriate patch cable lengths to maintain signal integrity. Keep transceiver dust caps in place when modules are not connected, and follow ESD handling procedures when inserting or removing SFPs. Verify compatibility with your switch or router model and consult the device documentation if explicit vendor firmware locking policies are enforced.
