Description
IEC-825 standards.
The DTR-xxx-SM-CWDM fiber optic transceivers offer a
simple and convenient way to interface PCBs to single mode
fiber optic cables in Coarse Wavelength Division Multiplexing
(CWDM) OC-3 and OC-12 applications. There are eight
center wavelengths available 1470 nm, 1490nm, 1510 nm,
1530 nm, 1550 nm, 1570 nm, 1590 nm, and 1610 nm. For
OC-3 application two performance options are offered,
“L0” and “HP”. In option “L0”, a DFB laser and a high
sensitivity receiver are used to increase the distance to 90
km (assuming worst case fiber loss of 0.3 dB/km), and in
option “HP”, a high power DFB laser and an ultra high
sensitivity receiver are used to increase the distance to 100
km or better. For OC-12 application, the “HP” power level
is standard using DFB laser to obtain the distance of at
least 80 km.
The transmit and receive functions are contained in a single
one-row, 9-pin (1x9) package with a Duplex SC or ST or
FC connector interface. The transmitter incorporates a
highly reliable DFB InGaAsP Laser and a driver circuit
which converts Positive Emitter Coupled Logic (PECL)
data to light. The receiver incorporates an efficient
InGaAs/InP PIN photodiode converting the light signal into
an electrical current which is amplified and regenerated
into PECL-compatible data. The transimpedance
amplifier IC has internal AGC for wide dynamic range.
A Signal Detect status output flag is also provided.
The transceiver operates from a single +5V power supply
over an operating temperature range of 0°C to +70°C. The
transceiver package is made of either conductive plastic
(Duplex-SC version) with blue color or metal
(FC and ST version) for excellent EMI shielding.
All modules satisfy Class I Laser Safety requirements in
accordance with the US FDA/CDRH and international

Application Notes
Transmitter: When the DATA+ input is at logic HIGH
and DATA- input is at logic LOW, the LD is ON; and
vice versa. In single-ended applications, the unused input
pin should be biased to VCC - 1.29 V.
DETECT output is PECL level requiring termination
(510 ohms to GND is recommended).
Interface circuit: The power supply line should be wellfiltered. All 0.1 mF power supply bypass capacitors should
be as close to the DTR transceiver module as possible.
The two front GND posts should be connected to Circuit
Ground or Chasis Ground. The termination resistors for
the Transmitter should be close to the DTR transceiver
module. The termination resistors for the Receiver should
be close to the PHY or SERDES device (which receives
the DATA outputs from the Receiver).
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).
+5 volt
Receiver: Both differential
DATA+ and DATA- outputs are
PECL levels requiring
termination (50 ohms to VCC - 2
volts or 510 ohms to GND is
recommended). For optimum
performance, both outputs
should be terminated in the
same manner, even if only one
is used.
The Signal Detect circuit
monitors the level of the
incoming optical signal and
generates a logic LOW signal
when insufficient optical power
is received. The SIGNAL
