Description
The DTR-1250-SM series of fiber optic transceivers provide
a quick and reliable interface for 1000BASE-LX Gigabit
Ethernet applications. In addition to option “L2” for the 5km
distance specified in IEEE 802.3z Draft D5.0, five other options
with longer distance capability are offered. Option “L1” uses
a high power 1310nm Fabry Perot laser with narrower spectral
width and center wavelength range to increase the distance to
at least 10km. Option “L0” uses an even higher power 1310nm
Fabry Perot laser to offer more optical link power budget.
Option “H3” uses a 1310nm DFB laser and a high sensitivity
receiver to increase the distance to 30km (assuming fiber loss
of 0.35dB/km). Option “H5” uses a 1550nm DFB laser and a
high sensitivity receiver to increase the distance to over 40km
(assuming fiber loss of 0.25dB/km). Finally, option “H7” uses
a high power 1550nm DFB laser and an ultra high sensitivity
receiver to increase the distance to 70km (assuming fiber loss
of 0.25dB/km). All modules satisfy Class I Laser Safety
requirements in accordance with the U.S. FDA/CDRH and
international IEC-825 standards.
The transmit and receive functions are contained in a single
one-row, 9-pin (1x9) package with a Duplex SC, ST or FC
optical interface. The transceiver package is made of either
PCI-mezzanine-compliant conductive plastic (Duplex SC
version) with blue coloring or metal (ST and FC version) for
excellent EMI shielding.
The transmitter and receiver data interfaces are differential
direct-coupled PECL. An alternate version with AC coupling
interface is also available. The receiver signal detect output
interface is direct-coupled PECL.
The transceivers operate from a single +5V power supply over
an operating case temperature range of 0°C to +70°C. A low
power consumption version with 3.3 V supply voltage is also
offered. Please refer to the DTR-1250-3.3-SM data sheet.

Application Notes
DATA interface (DC-coupled module): The interface circuit
for the standard DC-coupled module with direct-coupled PECL
interface is shown in Figure 1. The termination resistors for the
transmitter should be close to the DTR transceiver module. The
termination resistors for the receiver (50Ω to VCC - 2V or the
Thevenin equivalent resistors shown) should be close to the
PHY or SERDES IC, which receives the DATA outputs. When
interfacing with 3.3V SERDES IC, AC coupling can be used as
shown in Figure 2. The termination resistors required by the
SERDES are not shown in this figure.
DATA interface (AC-coupled module): For modules with AC
coupling option, both transmitter and receiver interfaces have
internal bias, termination and AC coupling capacitors. The
transmitter can be directly connected to the driving SERDES.
The receiver can be connected directly to the external 50Ω load
(termination resistor of the SERDES).
SIGNAL DETECT: The signal detect circuit monitors the level
of the incoming optical signal and generates a logic LOW signal
when an insufficient photocurrent is produced. The signal detect
output is PECL level requiring termination (510Ω to GND is
recommended).
The transmitter incorporates an Average Power Control (APC)
loop to stabilize the average optical output power against
temperature variation; 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” or “ON” level).
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 DTR transceiver module as possible.
The two front GND posts should be grounded to circuit ground
or chassis ground.
