The 10-pin configuration is in conformance to the SFF MSA. The DTR-2488-SM-LC/LS-W-G SFF series of fiber optic transceivers provide a quick and reliable interface for SONET/SDH OC-48/STM-16 short reach, intermediate reach and long reach applications. The short reach (SR-1) version uses a 1310nm Fabry Perot laser while the intermediate reach (IR-1) and long reach (LR-1) versions use a 1310nm DFB laser to achieve reaches of 2km, 15km and 40km, respectively. For intermediate reach (IR-2) and long reach (LR-2) versions, a 1550nm DFB laser is used to obtain the reaches of 15km and 80km, respectively. All modules are compliant with all applicable SONET/SDH OC-48/STM-16 standards and satisfy Class I Laser Safety requirements per U.S. FDA/CDRH and international IEC-60825 standards. The transmitter design incorporates all the necessary control and driver circuitry for converting differential data to light. The receiver uses an InGaAs/InP PIN photodiode for short reach and intermediate reach applications and an APD photodiode for long reach applications to covert the light signal into an electrical current which is amplified and regenerated into differential data outputs. AC-coupled transmit and receive DATA interface is recommended for compatibility with LV-PECL signal levels. An option for DC-coupled interface is also available. LV-TTL SIGNAL DETECT function is provided to indicate optical input loss. The transceivers operate from a single +3.3V power supply over an operating case temperature range of -5° to +70°C or -40° to +85°C (“A” option). The housing is made of metal to enhance EMI immunity. The transmit and receive functions are contained in a narrow width two-row, 10-pin (2x5) package with a duplex LC optical interface.

The transmitter input has internal 50Ω termination. SIGNAL DETECT: The SIGNAL DETECT circuit monitors the incoming optical signal level and generates a logic LOW signal when an insufficient photocurrent is produced. The output is LV-TTL with no termination required. DATA interface (AC-coupled modules): For modules with AC coupling option, both transmitter and receiver interfaces have internal bias, 50Ω termination and AC coupling capacitors. The transmitter can be connected directly to the driving SERDES as shown in Fig. 2. The receiver can be connected directly to the external 50Ω loads (termination resistor of the SERDES). For best performance, both DATA+ & DATAshould be used. TX DISABLE: 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 - 1.3V, the laser is turned off independent of the input data. 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 module case ground is internally AC-coupled to the circuit ground. 4 21737-0269, Rev.
