The Siemens Ethernet/Fast Ethernet/FDDI/ATM transceiver-part of Siemens Small Form Factor transceiver family is fully compliant with the Asynchronous Transfer Mode (ATM) OC-3 standard, the Fiber Distributed Data Interface (FDDI) Low Cost Fiber Physical Layer Medium Dependent (LCF-PMD) draft standard(1), and the FDDI PMD standard(2), and the SFF MSA.

This transceiver supports the innovative Volition connectorization concept, which competes with UTP/CAT 5 solutions. ATM  is compatible with RJ-45 style backpanels for fiber-to-the-desktop applications while providing the advantages of fiber optic technology.The receptacle accepts the new SG connector. The Small Form Factor is specially developed for distances of up to 2 km.

These ATM  transceivers also support 10 Base Fx 1300 nm with DCfree balanced coding (Manchester, 8B/10B).

Fast Ethernet was developed because of the higher bandwidth requirement in local area networking. ATM  is based on the proven effectiveness of millions of installed Ethernet systems.

ATM was developed because of the need for multimedia applications,including real time transmission. The data rate is scalable and the ATM protocol is the basis of the broadband public networks being standardized in the International Telegraph and  Telephone Consultative Committee (CCITT). ATM can also be used in local private applications.

FDDI is a Dual Token Ring standard developed in the U.S. by the Accredited National Standards Committee (ANSC) X3T9, within the Technical Committee X3T9.5. It is applied to the local area networks of stations, transferring data at 100 Mbits/s with a 125 MBaud transmission rate. The inputs/outputs of ATM  are PECL compatible and the unit operates from a 3.3 V power supply. As an option, the data output stages can be switched to static levels during absence of light, as indicated by the Signal Detect function. It can be directly interfaced with available chipsets.
