Remote Defect Indication
The minimum acceptable value of average received power at point R to achieve a 1 x
-12
10 BER (The FEC is open).
A kind of stable and high-precision autonous clock providing frequencies for other clocks
for reference.
A piece of equipment or device that regenerates electrical signals.
The process of receiving and reconstructing a digital signal so that the amplitudes,
waveforms and timing of its signal elements are constrained within specified limits.
The regenerator section overhead comprises rows 1 to 3 of the SOH of the STM-N signal.
A remote optical amplifier subsystem designed for applications where power supply and
monitoring systems are unavailable. The ROPA subsystem is a power compensation
solution to the ultra-long distance long hop (LHP) transmission.
A network topology being developed as a new standard for fiber optic rings.
Radio Frequency
Request For Announcement
Request for Information
A type of network topology in which each node connects to exactly two other nodes,
forming a circular pathway for signals.
Radio Network Controller
See Remote optical pumping amplifier
The path that network traffic takes from its source to its destination. In a TCP/IP network,
each IP packet is routed independently. Routes can change dynamically.
A device on the network layer that selects routes in the network. The router selects the
optimal route according to the destination address of the received packet through a
network and forwards the packet to the next router. The last router is responsible for
sending the packet to the destination host. Can be used to connect a LAN to a LAN, a
WAN to a WAN, or a LAN to the Internet.
Rendezvous Point
See Resilient Packet Ring
A asynchronous transfer mode that does not involve hand-shaking signal. It can
communicate with RS232 and RS422 of other stations in point-to-point mode and the
transmission is transparent. Its highest speed is 19.2kbit/s.
The specification that defines the electrical characteristics of balanced voltage digital
interface circuits. The interface can change to RS232 via the hardware jumper and others
are the same as RS232.
