Small Form Factor Transceiver Multisource Agreement
Cooperation Agreement for Small Form Factor Transceivers
Agilent Technologies, E2O Communications, Fujikura Technology America Corp, IBM Corp.,
Lucent Technologies Inc., Molex Inc., Sumitomo Electric Lightwave Corp., Tyco Electronics Inc.
I. Purpose of the Cooperation Agreement
Each party desires to establish internationally compatible sources of a fiber optic transceiver
module in support of standards for fiber optic systems including Asynchronous Transfer Mode
(ATM), FDDI, Fibre Channel, Fast Ethernet and Gigabit Ethernet, and Synchronous Optical
Network (SONET)/Synchronous Digital Hierarchy (SDH) applications. Each party further
desires to establish uniformity in the industry for the Transceiver “Package Outline”, “Circuit
Board Layout” and “Pin Function Definitions” described in Appendix A. Each party expects that
the establishment of compatible sources for an interchangeable transceiver module will allow
the entire fiber optic marketplace to grow more rapidly. This enhanced growth, providing more
customer choice and vigorous competition are the express purposes of the Agreement. The
parties desire to establish compatible sources for additional products in the future.
II. Agreement
A. General
The parties agree to cooperate by supporting common product interface specifications for fiber
optic transceivers with the package “Package Outline”, “Circuit Board Layout” and “Pin Function
Definitions” described here and in Appendix A. Initial products utilizing this agreement may
include Fiber Optic Transceivers at 100 to 2.5 Gb/s for multimode and single mode fiber
applications. Other fiber optic transceivers may follow as needed in the marketplace. The
mechanical dimensions shall be compatible with the package “Package Outline”, “Circuit Board
Layout” and “Pin Function Definitions” as shown in Appendix A. The overall package
dimensions shall not exceed the maximum indicated dimensions, and the pins and mounting
posts shall be located such that the products are mechanically interchangeable in a circuit
board. The electrical and optical specifications shall be compatible with those enumerated in
the appropriate standards (i.e., the IEEE 802.3z Gigabit Ethernet standard and the ITU G.957
Synchronous Digital Hierarchy standard). In addition, the parties may work together to
recommend circuit layouts for electrical input and output terminations, and grounding practices.
The transceivers per this agreement will accept an optical connector such as the duplex LC,
MT-RJ or the SC/DC connector. This agreement does not preclude any of the parties from
offering Small Form Factor transceivers for other connectors and vice-versa. Internal design of
the product is entirely at the discretion of each party and is not covered by this Agreement. The
parties recognize that their products may not be identical, but need only meet the above criteria.
