Multi-rate Gigabit Ethernet & FibreChannel
SFP CWDM Transceivers with Digital Diagnostics
TRPAG1M CWDM MR
The TRPAG1M CWDM SFP series of multi-rate fiber optic transceivers with
integrated digital diagnostics monitoring functionality provide a quick
and reliable interface for 1000BASE-LX Gigabit Ethernet and 1.062GBd
Fibre Channel applications. The transceivers are designed to support data
rates ranging from 1.25Gb/s down to 125Mb/s. Diagnostics monitoring
functionality (alarm and warning features) is integrated into the design
via an I2C serial interface per the Multi-Source Agreement (MSA) SFF-8472,
Rev. 9.3.
There are eight center wavelengths available: 1471nm, 1491nm, 1511nm,
1531nm, 1551nm, 1571nm, 1591nm and 1611nm. Two optical link power
budget options are offered, YX (22dB minimum) and ZX (24dB minimum).
They correspond to transmission distances of 62km and 70km, respectively
(assuming a total connector/splice/ CWDM mux and demux loss of 4.5dB,
allocated system penalty of 2dB and fiber loss of 0.25dB/km). All modules
satisfy Class I Laser Safety requirements in accordanc with the U.S. FDA/
CDRH and international IEC-60825 standards.
The TRPAG1M CWDM 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 ACcoupled 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 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 TTL compatible
and should be pulled up with a 4.7 - 10kΩ resistor on the
host board
and MOD_DEF(0) is TTL LOW. When the host system detects
this condition, it activates the serial protocol (standard
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 startand
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.
The data transfer protocol and the details of the mandatoryand
vendor specific data structures are defined in the SFPMSA, 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 latched per SFP MSA.
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),
