The new Intellinet Network Solutions Small Form Factor Pluggable (SFP) Transceiver provides the best combination of performance and affordability. This mini-GBIC (Gigabit Interface Converter) module provides a metal housing to reduce electromagnetic interference and increases durability.

Small Size for High-Density Fiber Connections

The transceiver is available as a mini-GBIC form factor, making it ideal for environments that require many fiber connections by taking up less space in your cabinet and/or computer room.

Multi-Vendor Compatible

Compatibility in your network is everything, and the Intellinet SFP Transceiver Module delivers. Use it with any Intellinet SFP equipped network switch or any other MSA-compliant, SFP-enabled switch. And since the Intellinet SFP transceiver module is set to broadcast the vendor on GLC-LH-SM, compatibility to your Cisco gear is provided.


No need to power down your LAN switch in order to install or remove the transceiver. This makes it very convenient and easy for you to make adjustments to your network that allow your business to keep pace with the changing demands of the market.
