PMC-Sierra has announced the availability of symmetric 10 Gigabit EPON chips. The devices complete the company's 10 Gigabit PON portfolio which also includes XGPON designs.
The 10G-EPON devices comprise two PAS9000 optical networking unit (ONU) and four PAS8000 optical line terminal (OLT) chips that support asymmetrical and symmetrical 10G-EPON: 10Gbps downstream (to the user) and 1Gbps upstream, and 10Gbps downstream and upstream, respectively. PMC-Sierra claims it is the first to market with a dual-mode 10G-EPON ONU device.
