SUPPORTED LINK LENGTHS Reach Category within Standard min. max.1) SDH STM S-1.1 0 15,000 SONET OC-3 IR-1 0 21,000 Unit meters Notes: 1) Maximum reach over fiber type SM-G.652 as defined by ITU-T G.957 and Telcordia GR-253-CORE standards. Longer reach possible depending upon link implementation. 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 ATM 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 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 155.520Mbit/s from a single power supply. The differential data inputs and outputs are DC-coupled and PECL compatible. © Finisar Corporation October 2006 Rev. A Preliminary Data 3 V23836-C18-R363 Product Specification – October 2006 FUNCTIONAL DESCRIPTION This transceiver is designed to transmit serial data via single mode fiber. Figure 2 Functional Diagram 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 present1). The transmitter converts electrical PECL compatible serial data (TD+ and TD–) into optical serial data. The transmitter contains a laser driver circuit that drives the modulation and bias currentof 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. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects transmitter failures or when VCC is too high. A reset is only possible by turning the power off, and then on again. Notes: 1) We recommend to switch off the transmitter supply (VCCTx) if no transmitter input data is applied © Finisar Corporation October 2006 Rev.

A Preliminary Data 8 V23836-C18-R363 Product Specification – October 2006 Eye Safety This laser based single mode transceiver is a Class 1 product. 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 AbsoluteMaximum 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)). Laser Emission Data Wavelength 1310 nm Maximum total output power (as defined by IEC: 7mm aperture at 14mm distance) 15.6 mW / 11.9 dBm Beam divergence (full angle) / NA (half angle) 11° / 0.1 rad Figure 3 Required Labels Figure 4 Laser Emmission © Finisar Corporation October 2006 Rev. A Preliminary Data 9 V23836-C18-R363 Product Specification – October 2006 Application Notes ATM transceivers and matching circuits are high frequency components and shall be terminated as recommended in the application notes for proper EMI performance. 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. Single Mode 155 Mbit/s ATM 1x9 Transceiver, DC/DC PECL Version Figure 5 © Finisar Corporation October 2006 Rev. A Preliminary Data 10 V23836-C18-R363 Product Specification – October 2006 This application note assumes Fiber Optic transceivers using 3.3V power supply and SerDes Chips using either 3.3V or 5V power supply. It also assumes no self biasing at the receiver data inputs (RD+/RD–) of the SerDes chip (Refer to the manufacturer Product Specification for other applications). Value of R1...R4 may vary as long as proper 50Ω termination to VEE or 100Ω 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). © Finisar Corporation October 2006 Rev.
