A kind of fiber used for connections between the subrack and the ODF, and for
connections between subracks or inside a subrack.
A high-speed transport technology used to build storage area networks (SANs). Fiber
channel can be on the networks carrying ATM and IP traffic. It is primarily used for
transporting SCSI traffic from servers to disk arrays. Fiber channel supports single-mode
and multi-mode fiber connections. Fiber channel signaling can run on both twisted pair
copper wires and coaxial cables. Fiber channel provides both connection-oriented and
connectionless services.
A new generation connection protocol which connects the host to various control units.
It carries single byte command protocol through the physical path of fiber channel, and
provides higher rate and better performance than ESCON.
A device installed at the end of a fiber, optical source or receive unit. It is used to couple
the optical wave to the fiber when connected to another device of the same type. A
connector can either connect two fiber ends or connect a fiber end and a optical source
(or a detector).
A standard developed by the American National Standards Institute (ANSI) for high-
speed fiber-optic local area networks (LANs). FDDI provides specifications for
transmission rates of 100 megabits (100 million bits) per second on networks based on
the token ring network.
General name of optical fiber and cable. It refers to the physical entities that connect the
transmission equipment, carry transmission objects (user information and network
management information) and perform the transmission function in the transmission
network. The optical fiber transmits optical signal, while the cable transmits electrical
signal. The fiber/cable between NEs represents the optical fiber connection or cable
connection between NEs. The fiber/cable between SDH NEs represents the connection
relationship between NEs. At this time, the fiber/cable is of optical fiber type.

Floating nuts (or as they are more correctly named, 'tee nuts') have a range of uses but
are more commonly used in the hobby for engine fixing (securing engine mounts to the
firewall), wing fixings, and undercarriage fixing.
An aggregation of packets that have the same characteristics. On the network
management system or NE software, flow is a group of classification rules. On boards,
it is a group of packets that have the same quality of service (QoS) operation.
See Frame loss ratio
For normal traffic signals, switches normal traffic signal to the protection section, unless
an equal or higher priority switch command is in effect or SF condition exists on the
protection section, by issuing a forced switch request for that traffic signal.
A bit error correction technology that adds the correction information to the payload at
the transmit end. Based on the correction information, the bit errors generated during
transmission are corrected at the receive end.
A class-based forwarding technology that classifies the packets with the same forwarding
mode. Packets with the same FEC are processed similarly on an MPLS network. The
division of FECs is flexible, and can be a combination of the source address, destination
address, source port, destination port, protocol type, and VPN.
