EPON

All services and traffic are transported between the OLT and an ONT over the
EPON. The EPON brings optical fiber cabling and signals to the subscriber. The
optical fiber network connecting the EPON OLT and the EPON ONT is a passive
optical network (PON) with no active or powered elements.
The EPON employs a point-to-multipoint topology. A single strand of fiber extends
from the OLT at the central office to a passive optical splitter. The splitter can handle
up to 64 ONTs on a PON.
The EPON network uses the following wavelengths of light between the P-OLT and
the ONTs across the EPON:
•
1310 nm voice/data transmit in the upstream
•
1490 nm voice/data receive in the downstream
