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 and ITU-T G.957 STM-1 S-1.1.

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 (5 V or 3.3 V).
The differential data inputs and outputs are DC-coupled and PECL compatible.

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

recommended by ANSI T1E1.2, SONET OC-3 and ITU-T G.957. BOL value –31 dBm max.
2) An increase in optical power of data signal above the specified level will cause the Signal Detect to switch from a low state to a

4) DC/DC, PECL for Signal Detect, PECL compatible. Load is 50Ω into VCC–2 V for data, 510 Ω to VEE for SignalDetect. Measured
under DC conditions. For dynamic measurements a tolerance of 50 mV should be added.VCC = 3.3 V. TAMB = 25°C.

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)).

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.

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).
