1.1 System Description
The chassis-based OLT2412 (Optical Line Terminal) connects and manages the end to end GPON
(Gigabit Passive Optical Network) solution for delivering broadband data, high-quality voice, and IP
television services. The OLT provides:
Fiber to the building (FTTB) or neighborhood (FTTN) connections for chassis-based Multi-Dwelling
Units (MDUs).
Fiber to the curb (FTTC) connections for standalone VDSL Outside Plant (OSP) MDUs.
Fiber to the home (FTTH) connections for Optical Network Terminal (ONT) subscriber devices.

The OLT is 5.7 U and installs in a standard 19-inch (482 mm) equipment rack. Temperature
hardening, front access, dual power modules for redundancy, dual management cards for
redundancy, and hot-swappability of all slots help maximize network uptime.
