It 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 (LCFPMD) draft standard(1), and the FDDI PMD standard(2). ATM was developed because of the need for multimedia applications, including real time transmission. JUNE 1999 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. Transmitter Electro-Optical Characteristics Fast Ethernet was developed because of the higher bandwidth requirement in local area networking. It is based on the proven effectiveness of millions of installed Ethernet systems. The Infineon multimode transceiver is a single unit comprised of a transmitter, a receiver, and an SC receptacle. This design frees the customer from many alignment and PC board layout concerns. The modules are designed for low cost applications.

Units Launched Power (Average) PO into 62.5 µm Fiber(1, 2) 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. LCF FDDI is specially developed for short distance applications of up to 500 m (fiber-to-the-desk) as compared to 2 km for backbone applications. Parameter Transmitter Typ. Max. Units 4.

To maintain good LED reliability, the device should not be held in the ON state for more than the specified time. Normal operation should be done with 50% duty cycle. 3. To achieve proper PECL output levels the 50 Ω termination should be done to VCC –2 V. For correct termination see the application notes.
