SFP Modules and Network Transceivers

SFP (Small Form-Factor Pluggable) modules connect networking equipment to fiber optic or copper cabling. Island Electrical Supply stocks SFP, SFP+, SFP28, and QSFP28 modules from HPE, SonicWall, Ubiquiti, and Netgear.

Best for: Network engineers adding fiber or high-speed copper uplinks to switches, routers, and firewalls.

SFP Module Types

Choose based on the speed and distance your connection requires:

  • SFP (1G): 1 Gbps connections over fiber (SX/LX) or copper (RJ45)
  • SFP+ (10G): 10 Gbps connections, available as short-reach (SR), long-reach (LR), or direct attach copper (DAC)
  • SFP28 (25G): 25 Gbps for modern data center uplinks
  • QSFP28 (100G): 100 Gbps for high-capacity backbone connections

Compatibility

SFP modules must be compatible with the switch or router they plug into. Most vendors use standard MSA (Multi-Source Agreement) form factors, but some equipment only accepts brand-specific modules. Check your equipment documentation or contact our team to confirm compatibility before ordering.

Frequently Asked Questions

What is an SFP module?

An SFP (Small Form-Factor Pluggable) module is a compact transceiver that plugs into a switch, router, or firewall to provide fiber optic or copper connectivity. SFP modules are hot-swappable, meaning you can install or replace them without powering down the equipment.

What is the difference between SFP and SFP+?

SFP supports speeds up to 1 Gbps while SFP+ supports up to 10 Gbps. SFP+ modules are physically the same size as SFP but use faster signaling. Most SFP+ ports are backward compatible with SFP modules at 1G speeds.

Do I need single-mode or multi-mode fiber SFP?

Multi-mode (SR/SX) SFPs are for short distances up to about 300 meters and use orange fiber cables. Single-mode (LR/LX) SFPs reach 10 to 80 kilometers and use yellow fiber cables. Use multi-mode for connections within a building and single-mode for connections between buildings.
