OC-3 1510nm Optical Supervisory
Channel SFP Transceiver
TRPA03E2ZBBS3
Product Description
The TRPA03E2ZBBS3 SFP fiber optic transceiver with integrated digital diagnostics
monitoring functionality provides a quick and reliable interface for optical
supervisory channel applications. The diagnostic functions, alarm and warning
features as described in the Multi-Source Agreement (MSA) document, SFF-8472
(Rev. 9.4), are provided via an I
2
C serial interface.
The TRPA03E2ZBBS3 transceiver uses a 1511nm DFB laser and an APD receiver to
provide an optical link power budget of 44dB. The transceiver satisfies Class I Laser
Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-
60825 standards.
The transceiver connects to a standard 20-pad connector for hot plug capability.
This allows the system designer to make configuration changes or maintenance
by simply plugging in different types of transceivers without removing the power
supply from the host system.
The transceiver has a blue bail-type latch, which offers an easy and convenient
way to release the module. The latch is compliant with the SFP MSA.
The transmitter and receiver DATA interfaces are AC coupled internally. LV-TTL
Transmitter Disable control input and Loss of Signal output interfaces are also
provided.
The transceiver operates from a single +3.3V power supply over an operating
case temperature range of -5°C to +70°C. The housing is made of metal for EMI
immunity.

Application Notes
Electrical Interface:
All signal interfaces are compliant with
the SFP MSA specification. The high speed DATA interface
is differential AC-coupled internally and can be directly
connected to a 3.3V SERDES IC. All low speed control and sense
output signals are open collector TTL compatible and should
be pulled up with a 4.7 - 10kΩ resistor on the host board
two-wire I
2
C serial interface) and generates the serial clock
signal (SCL). The positive edge clocks data into the EEPROM
segments of the SFP that are not write protected, and the
negative edge clocks data from the SFP.
The serial data signal (SDA) is for serial data transfer. The
host uses SDA in conjunction with SCL to mark the start and
end of serial protocol activation. The supported monitoring
functions are temperature, voltage, bias current, transmitter
power, average receiver signal, all alarms and warnings, and
software monitoring of TX Fault/LOS. To allow monitoring of
the average receiver signal level at sensitivity and maintain
compatiblity with exisiting systems 10dB needs to be
subtracted from the received optical power monitor output
to obtain the correct value of the received optical power. The
device is internally calibrated.
The data transfer protocol and the details of the mandatory
and vendor specific data structures are defined in the SFP
MSA, and SFF-8472, Rev. 9.4
Power Supply and Grounding:
The power supply line
shouldbe well-filtered. All 0.1μF power supply bypass
capacitors should be as close to the transceiver module
as possible.
Loss of Signal (LOS):
The Loss of Signal circuit monitors the
level of the incoming optical signal and generates a logic HIGH
when an insufficient photocurrent is produced.
TX_Fault:
The output indicates LOW when the transmitter
is operating normally, and HIGH with a laser fault including
laser end-of-life. TX Fault is an open collector/drain output
that should be pulled up with a 4.7 - 10kΩ resistor on the
host board. TX Fault is non-latching (automatically deasserts
when fault goes away).
TX_Disable:
When the TX Disable pin is at logic HIGH, the
transmitter optical output is disabled (less than -45dBm).
Serial Identification and Monitoring:
The module
definition of SFP is indicated by the three module definition
pins, MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2).
Upon power up, MOD_DEF(1:2) appear as NC (no connection),
and MOD_DEF(0) is TTL LOW. When the host system detects
this condition, it activates the serial protocol (standard
