Optical and Copper Cabling
Optical Transceivers
Optical transceivers convert electrical signals into optical signals and vice versa, enabling data transmission over fibre-optic cables. They consist of two main parts: a transmitter and a receiver. They are essential for high-speed communication in data centres, particularly for inter-rack and inter-data centre connections.
Various types, differentiated by form factor, distance, and wavelength type.
| SFP | 1GB |
| SFP+ | 10GB |
| QSFP and QSFP28/56/112/DD/112-DD/DD800 | up to 800Gbps |
| OSFP | 800Gbps |
Optical Connector Types
Fiber-optic cables have various types of connectors, each designed for a different purpose. The fiber connector types, sometimes called terminations, connect both sides of a fiber-optic cable to terminals, switches, adapters, and patch panels.
Ethernet LANs are mostly built using unshielded twisted-pair (UTP) copper cables. UTP cable comprises of eight copper wires that are grouped in four twisted pairs. Each pair has a color scheme: one wire is solid colored, and the other is the same color but striped. Color-coded labels are typically provided for T568A and T568B wiring configurations to ensure correct wire termination.
UTP cables support speeds up to 10 Gbps. To achieve higher speeds, the optical fibre must be used.
