DESCRIPTIONThe Infineon Fibre Channel multimode transceiver – part of
Infineon Small Form Factor transceiver family – is based on the
Physical Medium Depend (PMD) sublayer and baseband
medium, type (short wavelength), Fibre Channel
FC-PI 200-M5-SN-I, 200-M6-SN-I
FC-PI 100-M5-SN-I, 100-M6-SN-I
FC-PH2 100-M5-SN-I, FC-PH2 100-M6-SN-I.
The appropriate fiber optic cable is 62.5µm or 50µm multi-
mode fiber with LC™ connector.
Operating range over each optical fiber type at 2.125 GBd
Operating range over each optical fiber type at 1.0625 GBd The Infineon Fibre Channel multimode transceiver is a single
unit comprised of a transmitter, a receiver, and an LC™ recepta-
cle.
This transceiver supports the LC™ connectorization concept. It
is compatible with RJ-45 style backpanels for high end
DataCom and Telecom applications while providing the advan-
tages of fiber optic technology.
The module is designed for low cost SAN, LAN, WAN, Fibre
Channel applications. It can be used as the network end
deviceinterface in mainframes, workstations, servers, and
storage devices, and in a broad range of network devices such
as bridges, routers, hubs, and local and wide area switches.
This transceiver operates at 1.0625 GBd / 2.125 GBd from a sin-
gle power supply (+3.3 V). The full differential data inputs and
outputs are PECL and LVPECL compatible.
Functional Description of SFP TransceiverThis transceiver is designed to transmit serial data via
multimodecable.
Functional Diagram The receiver component converts the optical serial data into
PECL compatible electrical data (RD+ and RD–). The LOS of
Signal (LOS, active low) shows whether an optical signal is
present.
The transmitter converts PECL compatible electrical serial data
(TD+ and TD–) into optical serial data. Data lines are differen-
tially 100 Ω terminated.
The transmitter 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 out-
put 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 pre-
vent 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 laser fault to guarantee the laser Eye Safety.
The transceiver contains a supervisory circuit to control the
power supply. This circuit makes an internal reset signal when-
ever the supply voltage drops below the reset threshold. It
keeps the reset signal active for at least 140 milliseconds after
the voltage has risen above the reset threshold. During this
time the laser isinactive.
A low signal on TxDis enables transmitter. If TxDis is high or not
connected the transmitter is disabled.
The information which kind of SFP module has been plugged
into an SFP port can be read through the MOD-DEF interface.
The information is stored in an I2C-Eprom inside the SFP Trans-
ceiver.
TECHNICAL DATAThe electro-optical characteristics described in the following
tables are valid only for use under the recommended operating
conditions.
Recommended Operating Conditionsransmitter Electro-Optical CharacteristicsNotesInto multimode fiber, 62.5 µm or 50 µm diameter.Laser power is shut down if power supply is below VTH and
switched on if power supply is above VTH after tRES.Fibre Channel PI Standard.
Receiver Electro-Optical CharacteristicsNotesAverage optical power at which the BER is 1x10E–12. Measured
with a 27–1 NRZ PRBS and ER=9 dB.An increase in optical power above the specified level will cause the
LOS of Signal output to switch from a High state to a Low state.A decrease in optical power below the specified level will cause the
LOS of Signal to change from a Low state to a High state.AC/AC for data. Load 50 Ω to GND or 100 Ω differential. For dynamic
measurement a tolerance of 50 mV should be added.Supply current excluding Rx output load.Measured at the given Stressed Receiver Eyeclosure Penatly and

Regulatory Compliance
EYE SAFETYThis laser based multimode transceiver is a Class 1 product.
It complies with IEC 60825-1 and FDA 21 CFR 1040.10 and
To meet laser safety requirements the transceiver shall be oper-
ated within the Absolute Maximum Ratings.
Caution
All adjustments have been made at the factory prior to ship-
ment 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.Note
Failure to adhere to the above restrictions could result in a modifica-
tion 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)).
