Question

Accepted Answer

DWDM stands for Dense Wavelength Division Multiplexing, OSPF is Open Shortest Path First, EIGRP is Enhanced Interior Gateway Routing Protocol, OLT is Optical Line Terminal, and ONU is Optical Network Unit.

DWDM is a technology that multiplexes multiple optical carrier signals on a single optical fiber by using different wavelengths of laser light.
OSPF is a routing protocol used for exchanging routing information between routers in an IP network.
EIGRP is a Cisco proprietary routing protocol that uses a metric based on bandwidth, delay, reliability, load, and MTU to determine the best path to a destination.
OLT is a device that converts electrical signals into optical signals for transmission over fiber optic cables.
ONU is a device that receives optical signals from the OLT and converts them back into electrical signals for distribution to end-users.
