Optics

An optical transceiver is a network device that can both send and receive data. An optical transceiver is an important part of a fiber optic network and is used to convert electrical signals to optical signals and vice versa. An optical transceiver is connected to a dedicated port on a switch, router or other network device to convert the port into a fiber optic interface.

What type of optical transceivers exist?

There are different types of optical transceivers. But which optical transceiver is suitable for your situation? You can choose from the following types:

  • X2, XPAK, XFP, GBIC, GLC and XENPAK – transceivers: These optical transceivers are all suitable for 10G network applications such as 10GbE. The transfer rate of data over your network is significantly increased.
  • SFP, SFP+, QSFP & CPAK transceivers: A small form-factor pluggable (SFP) transceiver supports 1GbE data transfer. An SFP+ transceiver even supports up to 10GbE. These transceivers provide the ability to send data over a fiber optic link. QSFP, or quad small form factor pluggable, is another type of compact, hot-swappable transceiver.
