Description
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 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 factor outline. The 10-pin configuration is in conformance to a Small Form Factor (SFF) multisource transceiver agreement. 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 - 5C to +70C or - 40C to +85C ("A" option). The package is made of metal for excellent EMI shielding

Application Notes
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 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). Internal Termination (for "M" & "ME" version)
+3.3 volt 1 H coil or ferrite inductor 0.1 Capacitor values in F, Resistor values in ohm
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. 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 F 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).
