B Page 4 V23826-C18-Cxx/Cxxx, V23826-C18-Txx/Txxx Product Specification - July 2004 Description The Finisar single mode ATM transceiver complies with the ATM Forum's Network Compatible ATM for Local Network Applications document and ANSI's Broadband ISDN - Customer Installation Interfaces, Physical Media Dependent Specification, T1.646-1995, Bellcore-SONET OC-3 / IR-1/LR-1 and ITU-T G.957 STM-1 / S-1.1/L-1.1. ATM was developed to facilitate solutions in multimedia applications and 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 Telecommunications Union (ITU), the former International Telegraph and Telephone Consultative Committee (CCITT). ATM can also be used in local private applications. The Finisar single mode transceiver is a single unit comprised of a transmitter, a receiver, and an SC/ST(R) receptacle. This design frees the customer from many alignment and PC board layout concerns. The module is designed for low cost WAN applications. It can be used as the network end device interface in workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, and intelligent hubs, as well as wide area ATM switches. This transceiver operates at 155.520 Mbit/s from a single power supply (5 V or 3.3 V). The differential data inputs and outputs are PECL compatible. Functional Description This transceiver is designed to transmit serial data via single mode cable.

B Page 5 V23826-C18-Cxx/Cxxx, V23826-C18-Txx/Txxx Product Specification - July 2004 The transmitter converts electrical PECL compatible serial data (TD+ and TD-) into optical serial data. It contains a laser driver circuit that drives the modulation and bias current of the laser diode. The currents are controlled by a power control circuit to guarantee constant output power of the laser over temperature and aging. The power control uses the output of the monitor PIN diode (mechanically built into the laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the operating limits. This transceiver contains an Input Signal Monitor (ISM), that switches the optical power off if a continuously low level is applied at Data Input. The receiver component converts the optical serial data into PECL compatible electrical data (RD+ and RD-). The Signal Detect (SD, active high) shows whether optical data is present 1). This module is a Class 1 laser product, due to an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures. A reset is only possible by turning the power off, and then on again. The transceiver contains a supervisory circuit to monitor the power supply. This circuit makes an internal reset signal whenever the supply voltage drops below the reset threshold. It keeps the reset signal active for at least 15 milliseconds after the voltage has risen above the reset threshold. During this time the laser is inactive. Notes: 1) We recommend to switch off the transmitter supply (VCCTx) if no transmitter input data is applied. (c) Finisar Corporation July 09, 2004 Rev.

It complies with IEC 60825-1/A2: 2001 and FDA performance standards for laser products (21 CFR 1040.10 and 1040.11) except for deviations pursuant to Laser Notice 50, dated July 26, 2001. CLASS 1 LASER PRODUCT To meet laser safety requirements the transceiver shall be operated within the Absolute Maximum Ratings. Note: All adjustments have been made at the factory prior to shipment of the devices. No maintenance or alteration to the device is required. Tampering with or modifying the performance of the device will result in voided product warranty. Failure to adhere to the above restrictions could result in a modification that is considered an act of "manufacturing", and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (ref. 21 CFR 1040.10 (i)).

Electromagnetic emission may be caused by these components. To prevent emissions it is recommended that cutouts for the fiber connectors be designed as small as possible. It is recommended that the Tx plug and the Rx plug be separated with a bar that divides the duplex SC opening.

B Page 13 V23826-C18-Cxx/Cxxx, V23826-C18-Txx/Txxx Product Specification - July 2004 3.3 V-transceivers can be directly connected to SerDes chips using standard PECL termination network. Value of R1...R4 may vary as long as proper 50 termination to VEE or 100 differential is provided. The power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module VCCRx/VCCTx. Further application notes for electrical interfacing are available upon request. Ask for Appnote 82. We strongly recommend a VEE plane under the module for getting good EMI performance. The transceiver contains an automatic shutdown circuit. Reset is only possible if the power is turned off, and then on again. (VCCTx switched below VTH). Application Board available on request. (c) Finisar Corporation July 09, 2004 Rev.
