Eye Safe (Class I Laser Safety) ! Multi-sourced 20-pin (2x10) SFF (Small Form Factor) package style ! Duplex LC optical connector interface ! Excellent EMI & ESD protection ! Single +3.3 V supply & LV-PECL DATA interface ! Option for LV-TTL or LV-PECL SIGNAL DETECT output Description The DTR-xxx-SM2-LC/LS-CWDM fiber optic transceivers offer a simple, convenient way to interface PCBs to single mode fiber optic cables in Coarse Wavelength Division Multiplexing (CWDM) applications. There are eight center wavelengths available 1470 nm, 1490 nm, 1510 nm, 1530 nm, 1550 nm, 1570 nm, 1590 nm, 1610 nm. For OC-3 applications two performance options are available, “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 lase is used to improve link budget and increase the distance to 100 km or better. For OC-12 applications, the “HP” power level is used with the DFB laser to obtain distance of at least 80 km. The transmit and receive functions are contained in a narrow width two-row, 20-pin (2x10) package with a Duplex LC connector interface. The receptacle fits into an RJ-45 form factor outline. The 20-pin configuration is in conformance to a Small Form Factor (SFF) multisource transceiver agreement. The transmitter incorporates a highly reliable 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 0°C to +70°C. The package is made of metal for excellent EMI shielding All modules satisfy Class I Laser Safety requirements in accordance with the US FDA/CDRH and international IEC-825 standards.

Application Notes If the SIGNAL DETECT output is LV-PECL level, a termination resistor of 160 ohms to GND 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 - 1.3 V, the laser is turned off independent of the input data. 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 circuit 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).
