KT approves Tellion-Passave FTTH EPON ONU, OLT

June 30, 2005 Santa Clara, CA -- Passave and Tellion today announced that Tellion's EP 3120 optical line terminal (OLT) and EP 3204 residential-gateway optical networking unit (ONU) have successfully passed benchmark testing by Korea Telecom (KT), and are now qualified for deployment in Korea. The OLT and ONU devices are designed around Passave's PAS6201 Gigabit EPON chipset.

According to the companies, the PAS6201 device in the customer-premises-based EP 3204 incorporates an ARM9 CPU that offers comprehensive networking functionality, making it unique among EPON devices in providing full residential-gateway services.

In the central office, the EP 3120 incorporates Passave's PAS5001 FTTH central-office EPON device. The PAS5001 integrates a advanced, programmable Dynamic Bandwidth Allocation (DBA) engine, which runs multiple DBA algorithms, including an algorithm developed by KT.

"Our four-port residential gateway offers carriers the advanced capabilities of the world's most highly integrated ONU chip, the Passave PAS6201, along with demonstrated leading broadband performance, while offering an unprecedented reduction in the bill of materials with respect to the cost of other ONU solutions," remarks Kim Jae Guen, CEO and president of Tellion.

"At Passave we have a vision of gigabit FTTH transforming communications throughout the world," adds Ariel Maislos, president of Passave. "Having shipped more than a million ONU devices to Japan, we are pleased to see our third-generation ONU system-on-chip qualify for deployment in Korea. The Korean market has shown rapid adoption of broadband, and is likely to become a role model for acceptance and adoption of FTTH as well."
