Depending on the networking devices and interfaces used in the data center, you can use a number of fiber optic cable connectors, as follows:
- ST
- SC
- LC
- FC
- MT-RJ
The latest type of fiber connector is the LC (Lucent/Little/Local Connector) connector. This has replaced older ST and SC models in network environments because of its small size. LC connectors usually can be found in pairs with a small bracket that unites the Transmit and the Receive fibers and that can be installed in a single connection into the network device.
The copper connectors most often used include the following:
- RJ45
- RJ11
- BNC
- F connector
- DB-9 serial connector
In order to concentrate all network connectivity, data centers’ connectivity racks often contain so-called 110 blocks in which you can punch in the Ethernet wires using a dedicated tool called a punch tool.
An alternative to 110 blocks is using patch panels in the data centers to ensure connectivity to the rest of the building. One side of the patch panel features punch down panels, while the other side features standard RJ45 jacks in which you can plug in UTP cables. Patch panels are often used to extend connectivity from each floor of the building to the data center, thus connecting all user devices to the network infrastructure.
