What is an SBC?

A Session Border Controller (SBC) is a network device or software solution that manages and secures real-time communication sessions across IP networks. These sessions typically use the Session Initiation Protocol (SIP) for call signaling.

Originally designed to manage SIP traffic between service providers, SBCs are now widely used in enterprise VoIP systems. They sit between internal networks (such as IP PBX systems) and external networks (like SIP trunk providers), acting as a border control mechanism.

What is an Optical SFP?

SFP stands for Small Form-factor Pluggable. It is a compact, hot-swappable transceiver module used to connect networking devices to fiber optic cables.

An Optical SFP converts electrical signals from a network device into optical signals for transmission over fiber. At the receiving end, another SFP converts the optical signal back into electrical form. This process enables high-speed communication across long distances with minimal signal loss.

What is Optical Fiber Cable?

An optical fiber cable is a high-speed data transmission medium made of thin strands of glass or plastic that carry information as pulses of light. Unlike traditional copper cables that transmit electrical signals, optical fibers use light to transmit data, which allows for faster, more reliable, and long-distance communication. Optical fiber cables are the backbone of modern telecommunications, internet services, and enterprise networks.

What Is an FXO VoIP Gateway?

An FXO VoIP Gateway is a device designed to connect analog PSTN lines to an IP-based voice network. FXO (Foreign Exchange Office) ports are used to receive services from a telephone company line, such as dial tone and incoming calls. By converting analog voice signals into IP packets, the gateway enables seamless call routing between traditional phone lines and VoIP platforms.

What Is an 8 Port EPON OLT?

An 8 Port EPON OLT is an optical line terminal equipped with eight EPON ports, each capable of supporting multiple ONUs through passive optical splitters. Depending on the split ratio (such as 1:32 or 1:64), a single device can serve hundreds of end users. This makes it ideal for medium to large-scale deployments where network expansion and subscriber growth are expected.
