Agere Systems and Agilent Technologies Announce Multisource Agreement for 10 Gigabit Ethernet Transceiver Physical Standards

FOR RELEASE MONDAY MARCH 12, 2001

ALLENTOWN, Pa. and PALO ALTO, Calif. - Agere Systems, formerly known as the Microelectronics Group of Lucent Technologies (NYSE: LU), and Agilent Technologies (NYSE: A) today announced a multi-source agreement (MSA) for 10 Gigabit Ethernet fiber optic transceivers. The agreement is the first developed to support the proposed IEEE 10 Gigabit Ethernet interoperability standard, and specifies a uniform form factor, size, connector type and electrical pin-outs.

Agere and Agilent will independently develop 10 Gigabit Ethernet transceivers based on the proposed IEEE standard and this MSA.

The MSA covers all four transceiver types defined in the proposed standard, including 850 nanometers (nm) serial, 1310 nm serial, 1310 nm WWDM and 1550 nm serial. It specifies transceiver modules not to exceed 38 millimeters (mm) (1.5 inches) wide, 121 mm (4.8 inches) long and 17.4 mm (0.7 inches) high. The specified dimensions will allow high port densities on typical line cards. The transceivers will be front-panel-pluggable devices, connecting to a host circuit board in the "Z" plane through a board-mounted card-edge connector. The optical interface will be a standard SC duplex fiber optic connector.

In addition, Tyco Electronics has designed, and will produce, a 70 pin electrical connector that connects the transceiver to the printed circuit board. The electrical input/output is based on the four wire XAUI (10 gigabit attachment unit interface) interface. The three companies will make the details of the MSA available to the industry so that other optical transceiver manufacturers can produce compatible products.

"Agilent and Agere are committed to supporting the Gigabit Ethernet standards developed by IEEE," said Euan Livingston, Agilent's Fiber Optic Business Unit marketing manager. "The pin-to-pin compatibility of transceivers from the two companies, and eventually others, will allow the devices to be used interchangeably. We plan to make the details of the MSA available to the industry shortly."

"This MSA offers a robust platform for all types of 10 Gigabit Ethernet devices," said Ed Cornejo, senior program manager at Agere Systems. "The design addresses the major challenges associated with 10 gigabit-per-second solutions, such as RFI issues, heat dissipation, manufacturability, pin assignments within the connector, and flexibility for other technologies. Our customers like the approach we've taken."

The companies expect to begin shipping these new 10 Gigabit Ethernet transceivers in 2001.
