Information about Network Transceivers

Network transceivers, short for transmitter-receiver, are devices that both transmit and receive analog or digital signals. The term is used most frequently to describe the component in a local-area network (LAN) that actually applies signals onto the network wire and also detects signals passing through the same wire. For many LANs, the transceiver is built directly into the network interface card (NIC). Some types of networks, however, require an external transceiver.

Products & Services Related to Network Transceivers

Network Firewalls

Network firewalls are systems that enforce access control policy between an organization's network and the Internet for security purposes.

Network Gateways

Network gateways interconnect networks with different, incompatible communication protocols.

Network Hubs

Network hubs serve as the central location for attaching wires to workstations.

Network Repeaters

Network repeaters regenerate incoming electrical, wireless or optical signals to preserve signal integrity and extend the distance over which data can travel. They are often used to connect cable segments in IEEE 802.3 networks.

Network Routers

Network routers are protocol-dependent devices that connect subnetworks. They are also used to break down a large network into smaller subnetworks.

Network Switches

Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.

VoIP and IP Telephony

VoIP and IP telephony allows PC users to make phone calls over the Internet or other packet networks via gateways and standard telephones.
