Description
factor outline. The 10-pin configuration is in conformance
to a Small Form Factor (SFF) multisource transceiver
agreement.
The DTR-622-SM-LC-MR and DTR-622-SM-LS-MR fiber
optic transceivers offer a simple, convenient way to
interface PCBs to single mode fiber optic cables. These
multi-rate transceivers are designed with performance
versions that are fully compliant with SONET/SDH standards
for OC-12/STM-4 data rate for Short Reach (12/2 km),
Intermediate Reach (21/15 km) and Long Reach
(42/40 km and 85/80 km) specifications. The modules also
operate down to OC-3/STM-1 data rate. All modules satisfy
Class I Laser Safety requirements in accordance with the
US FDA/CDRH and international IEC-825 standards.
The transmitter incorporates a highly reliable 1300 nm or
1550 nm InGaAsP Laser and a driver circuit which converts
LV-PECL data to light. A LV-TTL Transmitter Disable
control input is also provided. The receiver features a
transimpedance amplifier IC with internal AGC for high
sensitivity and wide dynamic range. The Signal Detect
status output can be either LV-TTL or LV-PECL.
The transceiver operates from a single +3.3V power supply
over an operating temperature range of - 5°C to +70°C or
- 40°C to +85°C (“A” option). The package is made of
metal for excellent EMI shielding
The transmit and receive functions are contained in a narrow
width two-row, 10-pin (2x5) package with a Duplex LC
connector interface. The receptacle fits into an RJ-45 form

OC-12/STM-4 LC Single Mode Transceiver: DTR-622-SM-LC/LS-MR
Application Notes
Receiver: Both differential DATA+ and DATA- outputs are LVPECL levels requiring proper termination (see recommended
interface circuits). For optimum performance, both outputs
should be terminated in the same manner, even if only one is
used.
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 - 1.3 V, the
laser is turned off independent of the input data. The transmitter
has two options for input termination. With “MS” and “MSE”
versions, the transmitter input interface is standard LV-PECL(i.e.
normal resistor termination needs to be provided by the end
user). With the “M” and “ME” version, an internal differential
100 ohm resistor termination is provided at the transmitter input
interface for convenience (see circuit diagrams below.)
The Signal Detect circuit monitors the level of the incoming
optical signal and generates a logic LOW signal when
insufficient photocurrent is produced. If the SIGNAL DETECT
output is LV-TTL level, no termination is required. If the SIGNAL
DETECT output is LV-PECL level, a termination resistor of 160
ohms to GND is required.
Interface circuit: The power supply line should be well-filtered.
All 0.1 µF power supply bypass capacitors should be as close
to the DTR transceiver module as possible. The two front GND
posts (mounting studs) should be grounded to Circuit Ground
or Chassis Ground. The Transmitter has internal 50 ohm
termination (see interface circuits).
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).
