FP
Flow Point —
An Ethernet Flow Point is a reference point that represents a location of transfer of
connectionless traffic units between topological components. A Flow Point can represent a
location of a physical port or individual sub-flow within a physical port such as a VLAN.
FPP
Flow Point Pool — The termination of a link is called a Flow Point Pool. The FPP describes
configuration information associated with an interface, such as a UNI or NNI.
Frame Short for Ethernet frame
FRU Field Replaceable Unit
FWM
Four-Wave Mixing —
FWM can occur in WDM systems when multiple wavelengths combine to
form new wavelengths. FWM can decrease channel spacing of wavelengths and have high
signal power levels.

I-SID
Service Instance Identifier — The I-SID is assigned for a service. The service ID is part of the
payload in provider backbone bridges per IEEE 802.1ah. I-SIDs provide additional network
security. I-
SID is a unique identifier used to ensure that users only receive traffic and services for
their respective subscription agreements.
IP
Internet Protocol — Data packets are forwarded from node to node based on the four-byte
destination IP address.
IPMI Intelligent Platform Management Interface
Ingress Frame A service frame sent from the CE to the service provider network.
IS In Service
ITU-T International Telecommunication Union-Telecommunication standards sector
Kbps Kilobits per second
LAC
Lambda Aggregator CWDM — The Cyan Z-Series Lambda Aggregator CWDM terminal
multiplexer module provides up to eight CWDM wavelengths for use in the Cyan Z-Series
multi-layer transport platforms. Each LAC provides optical multiplexing and demultiplexing
capability in the 1470nm to 1610nm band with 20nm spacing.
LACP
Link Aggregation Control Protocol (LACP) is a method of bundling several physical ports
together to form a single logical channel.
LACPDU
Link Aggregation Control Protocol Data Unit —
Two devices exchange LACPDUs in the process
of forming a LAG.
LAD
Lambda Add/Drop — The Cyan Z-Series LAD lambda add/drop DWDM terminal multiplexer
modules are available in four or eight 10G wavelength models for use in the Cyan Z-Series
multi-layer transport platforms. Each LAD provides optical add/drop multiplexing capability in
the 1550nm band across predefined ITU channel designations with 100 GHz spacings.
LAG
Link Aggregation Group — Link Aggregation Group allows for the grouping of Ethernet
interfaces to form a single link layer interface. LAGs provide a logical aggregation of bandwidth
and link redundancy (fault tolerance).
Lambda A wavelength used to carry one or more data channels in a WDM or DWDM system.
