OPLINK TRPA12MCWDM

Multi-rate OC-12/STM-4 SFP CWDM Single Mode
Transceivers withDigital Diagnostics
TRPA12M CWDM
Product Description
The TRPA12M CWDM SFP series of multi-rate transceivers with integrated digital
diagnostics monitoring functionality provide a quick and reliable interface
for long reach (LR) applications. The diagnostic functions, alarm and warning
features as described in the Multi-Source Agreement (MSA) document, SFF8472 (Rev. 9.3), are provided via an I2C serial interface.
Products under this series are compatible with SONET/SDH standards for OC12/STM-4 LR-2/L-4.2 and are capable of operating down to 155Mb/s data rate.
There are eight (8) wavelengths available: 1471nm, 1491nm, 1511nm, 1531nm,
1551nm, 1571nm, 1591nm and 1611nm. Two optical link power budgets are
available, 27dB and 29dB, providing an extra 2dB and 4dB over SONET/SDH
link budgets, respectively, to accommodate the wavelength multiplexing
and de-multiplexing insertion losses. All modules satisfy Class I Laser Safety
requirements in accordance with the U.S. and international standards as
described in the FDA/CDRH and IEC-60825 documents, respectively.
The TRPA12M CWDM multi-rate transceivers connect to standard 20-pad SFP
connectors 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 transceivers have colored bail-type latches, which offer an easy and
convenient way to release the modules. 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 transceivers operate from a single +3.3V power supply over an operating
case temperature range of -5°C to +70°C (“B” option) or -5°C to +85°C (“E”
option). The housing is made of plastic and 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 with 0.1μF and can be
directly connected to a 3.3V SERDES IC. All low speed control
and sense output signals are open collector TTLcompatible
and should be pulled up with a 4.7 - 10kΩ resistor on the
host board
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
two-wire I2C 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.
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.
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 internal temperature, supply voltage, bias
current, transmitter power, average receiver signal, all alarms
and warnings and software monitoring of TX Fault/LOS. The
device is internally calibrated.
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).
The data transfer protocol and the details of the mandatory
and vendor specific data structures are defined in the SFPMSA,
and SFF-8472, Rev. 9.4
TX_Disable: When the TX Disable pin is at logic HIGH, the
transmitter optical output is disabled (less than -35dBm).
Power Supply and Grounding: The power supply line
should be well-filtered. All 0.1μF power supply bypass
capacitors should be as close to the transceiver module
as possible.
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).
