Network Transceivers, Fiber Connectors, Copper Connectors, and Network Topologies

Transceiver

A device that combines the functionality of a transmitter and a receiver, allowing for modular connections in networking equipment.

SFP

Small Form-factor Pluggable, a type of transceiver that can support Gigabit Ethernet connections.

SFP+

Enhanced Small Form-factor Pluggable, a version of SFP that supports higher speeds, up to 16 gigabits per second.

QSFP

Quad Small Form-factor Pluggable, allowing for four times the throughput in a space similar to an SFP.

MPO

Multi-fiber Push On, a connector type that contains multiple fibers, typically 12, in a single connection.

SC Connector

Subscriber Connector, a common type of fiber connector that is square and locks in place.

LC Connector

Local Connector, a smaller fiber connector that uses a clip for locking into place.

ST Connector

Straight Tip, a fiber connector that locks in place using a bayonet coupling mechanism.

RJ11

Registered Jack type 11, a six-position connector typically used for telephone and DSL connections.

RJ45

Registered Jack type 45, an eight-position connector used for Ethernet connections.

F-Connector

A coaxial connector that provides a secure connection for cable modem applications, often threaded.

BNC Connector

Bayonet Neill-Concelman connector, a twist-lock connector commonly used for coaxial applications.

Star Network

A network topology where all devices connect to a central device, such as an Ethernet switch.

Mesh Network

A network design where multiple connections exist between devices, providing redundancy and load balancing.

Hybrid Network

A network architecture that combines different types of topologies, such as star and mesh.

Spine and Leaf Architecture

A data center design where spine switches connect to multiple leaf switches, ensuring efficient communication.

Point-to-Point Connection

A single connection between two points, commonly used in older WAN designs like T1 or T3.
