Description
The transmitter design incorporates a highly reliable
1310nm or 1550nm InGaAsP laser and an integrated driver
circuit. The receiver features a transimpedance amplifier
IC optimized for high sensitivity and wide dynamic range.
The signal detect status output is povided and can be either
LV-TTL or LV-PECL.
The DTR-xxx-SM-LC-W and DTR-xxx-SM-LS-W series
of fiber optic transceivers provide a quick and reliable
interface for short reach (SR), intermediate reach (IR)
and long reach (LR) applications. Available products under
this series are compliant with SONET/SDH standards for
OC-3/STM-1 and OC-12/STM-4. All modules satisfy Class
I Laser Safety requirements in accordance with the U.S.
FDA/CDRH and international IEC-825 standards.
The transceivers operate from a single +3.3V power supply
over an operating case temperature range of -5°C to +70°C
or -40°C to +85°C (“A” option). The housing is made of
metal for excellent EMI immunity.
The transmit and receive functions are contained in a
narrow two-row, 10-pin (2x5) package with a duplex LC
optical interface. The receptacle fits into an RJ-45 form
factor outline. The 10-pin configuration is in conformance
to the SFF MSA.

is required.
Transmitter: When the DATA+ input is at logic HIGH and
DATA- input is at logic LOW, the laser diode is on; and vice
versa. The transmitter is normally enabled (i.e. when the TX
Disable control input is not connected). When the TX Disable
control input voltage is higher than VCC - 1.3V, the laser is turned
off independent of the input data. The transmitter has two
options for input termination. With “WS” and “WSE” versions,
the transmitter input interface is standard LV-PECL (i.e. normal
resistor termination needs to be provided externally by the user).
With the “W” and “WE” version, an internal differential 100Ω
resistor termination is provided at the transmitter input interface
for convenience (see circuit diagrams on page 5).
Interface circuit: The power supply line should be well-filtered.
All 0.1µF power supply bypass capacitors should be as close
to the DTR transceiver module as possible. The two front ground
posts (mounting studs) should be grounded to circuit ground
or chassis ground.
Pin Assignments
PIN
The transmitter incorporates an Average Power Control (APC)
loop to stabilize the transmitter average optical output power
against temperature variation. The APC loop always acts to
keep the transmitter average optical output power at a constant
value. Therefore, when the input data is all continuous “zeroes”
or all continuous “ones,” the transmitter optical output power
is a constant level equal to the nominal average optical output
power (not at the “off” level or at the “on” level).
Receiver: Both differential DATA+ and DATA- outputs are
LV-PECL levels requiring proper termination (see circuit diagram
on page 5). For optimum performance, both outputs should be
terminated in the same manner, even if only one is used.
