Transceivers
Small devices that make a big impact in keeping your network up and running! Transceivers are a critical building block that act as the interface between your networking equipment and cabling. We know how important these small but mighty devices are and we’ve got you covered with a wide variety of transceivers for your network!
SFP/SFP+ Transceivers
These compact “small form-factor pluggable” SFP and SFP+ transceivers are some of the most popular on the market today. They feature a small size and high bandwidth (10Gbps for SFP+), while also providing for scalability within a network. In addition, they are hot-pluggable and backwards compatible which makes them an ideal solution for many networks!
Reach
Whether you need a solution for a short run, or a longer distance run, there is an SFP/SFP+ transceiver that will meet your needs. Transceivers that transmit over singlemode fiber (SMF) are capable of reaching distances up to 10km. If you’re looking for a shorter range connection, those transceivers that operate using multi-mode fiber (MMF) transmit over distances up to 500 meters, while transceivers using copper can reach distances of up to 100 meters.
Transfer Rate
Historically speaking, Gigabit Ethernet networks have been a popular choice among many small to mid-sized businesses. However, advances in technology and increasing needs for additional bandwidth have resulted in a widespread adoption of 10 Gigabit networks in recent years. As such, SFP and SFP+ transceivers remain some of the most in-demand products due to their Gigabit and 10 Gigabit transfer rates.
Copper vs. Fiber
There are plenty of SFP/SFP+ transceivers for networks of all types. Copper can be a popular choice for short-run applications, especially when trying to keep costs low. Transceivers that transmit over fiber cable are a popular choice amongst those looking for longer distance transmissions and increased performance. The right choice largely depends on the existing setup of your network and your specific needs.

High Speed Transceivers
It's no secret that the world of technology is constantly evolving, and that evolution means getting faster! With the increasing demands for high speed, high bandwidth networks, many are upgrading to 40G or 100G networks in order to meet current demands and future proof for the years to come. As such, higher bandwidth transceiver modules are required. Check out our selection of Cisco QSFP+ and QSFP28 transceiver modules.
High Density
These transceiver modules allow for increased density due to their breakout ability. 40G QSFP+ modules are capable of breaking out into 4 x 10G, while 100G QSFP28 modules are capable of breaking out into 4 x 28G.
Transmission Capacity
These 40G and 100G transceiver modules offer an extremely high transmission capacity when compared to their 1G and 10G predecessors.
Interface
These high transmission transceivers come in one of two interfaces: LC Duplex or MPO/MTP. Generally speaking, the LC duplex transceivers are ideal for long runs, while the MPO/MTP transceivers are an excellent choice for shorter runs.
