The PAS5001 EPON OLT is a gigabit Ethernet chip dedicated for use
in an Ethernet Passive Optical Network (EPON) Central Office (CO)
OLT device. The PAS5001 integrates the Ethernet Media Access
Control (MAC) functionality with the EPON protocol management on a
single chip. The PMC-Sierra PAS5001 EPON OLThas been shipping in
volume since 2004.
PMC-Sierra gigabit PON devices are based on the GigaPASS™ FTTH architecture that incorporates a gigabit PON to gigabit Ethernet interconnect
with wire-speed packet processing and a programmable 32-bit RISC
platform. The GigaPASS architecture is a powerful technical
foundation on which to build high-speed, high-performance PON
network devices.
PROGRAMMABLE DYNAMIC BANDWIDTH ALLOCATION
PMC-Sierra's standard DBA algorithms can allocate bandwidth based
on multiple priority levels, as well as bandwidth availability
guarantees made by the service provider, to ensure the highest
quality of service. In addition to PMC-Sierra's standard
programmable DBA algorithms, PMC-Sierra can work with carriers and
system OEMs who wish to develop custom algorithms. Please contact
your PMC-Sierra representative for more information.
