Angled physical contact (APC) connector

A single-mode optical-fiber connector whose angled end-face helps to ensure low mated reflectance and low unmated reflectance. The ferrule is polished at an angle to ensure physical contact with the ferrule of another APC connector.

Angular misalignment loss

The loss of optical power caused by deviation from optimum alignment of fiber-to-fiber. Loss at a connector due to fiber angles being misaligned because the fiber ends meet at an angle.

ARCnet (Attached Resource Computer network)
Developed by Datapoint, a relatively low-speed form of LAN data link technology (2.5Mbps, in which all systems are attached to a common coaxial cable or an active or passive hub). ARCnet uses a token-bus form of medium access control; only the system that has the token can transmit.

ARP table
A table used by the ARP protocol on TCP/IP-based network nodes that contains known TCP/IP addresses and their associated MAC (media access control) addresses. The table is cached in memory so that ARP lookups do not have to be performed for frequently accessed TCP/IP and MAC addresses.

Array connector

A connector designed for use with multiple optical fibers; see also MPT and MPO connectors.

Asymmetric Digital Subscriber Line (ADSL)
Sometimes called Universal ADSL, G.Lite, or simply DSL. ADSL is a digital communications method that allows high-speed connections between a central office (CO) and telephone subscriber over a regular pair of phone wires. It uses different speeds for uploading and downloading (hence the Asymmetric in ADSL) and is most often used for Internet connections to homes or businesses.
