EPON 8PON OLT(WEB+NMS Management)

EPON 8PON OLT(WEB+NMS management)

Q:  OLT function  ?

A: Optical line terminal ( optical line terminal ) , used to connect the terminal equipment of the optical fiber trunk line.  Features 1 : send ethernet data to ONU , by broadcasting l 2； Initiated and control the ranging process, and record the ranging information . 3: Allocate bandwidth for ONU , that is , control the start time and send window size of ONU sending data. 

The central office equipment ( OLT ) in the EPON passive optical network system is a multi-service provision platform that supports IP services and traditional TDM services at the same time. Placed at the edge of the metropolitan area network or at the exit of the community access netowrk, converge access services and deliver them to the IP network respectively.
