They are fully compliant to all applicable SONET/SDH specifications. The Short Reach version uses a 1300 nm Fabry Perot Laser while the Intermediate Reach version uses a 1300 nm DFB Laser. All modules satisfy Class I Laser Safety requirements in accordance with the US FDA/CDRH and international IEC-825 IEC-825 standards. The transmitter incorporates all the necessary control and driver circuitry for converting differential data to light. The receiver uses an InGaAs/InP PIN photodiode to convert the light signal into an electrical current which is amplified and regenerated into differential data outputs. The transmitter and receiver DATA interfaces are compatible with LV-PECL signal levels. An alternate version with AC coupling interface is also available. A LV-TTL Signal Detect function which indicates loss of optical input is also provided. The transmit and receive functions are contained in two-row, 10-pin (2x5) package with Duplex LC connector interface. The receptacle fits into an RJ-45 RJ-45 form factor outline. The 10-pin configuration is in conformance to a Small Form Factor (SFF) multisource transceiver agreement. The transceiver operates from a single +3.3V power supply over an operating temperature range of 0°C to +70°C or -40°C to +85°C ("A" Option). The package is either conductive plastic or metal for excellent EMI shielding.

Application Notes +3.3 volt DATA interface (AC-coupled modules): For modules with AC coupling option, both transmitter and receiver interface has internal bias, 50 ohm termination and AC coupling capacitor. The transmitter can be connected directly to the driving SERDES as shown in Fig. 2. The receiver can be connected directly to the external 50 ohm loads (termination resistor of the SERDES). For best performance, both DATA+ & DATA- should be used. + 0 .1 10 0 .1 160 1 mH co il o r 2 10 9 6 fe rrite in d uc to r + 100 0 .1 DTR-2488-SM DTR-2488-SM 50 o hm line RD+ 5 3 8 1 G ND POSTS 1 0 0 LV -P E C L 50 o hm line RD T X D IS A B L E LV -P E C L 50 o hm line TD - S IG N A L D E T E C T 160 50 o hm line TD + 10 SIGNAL DETECT: The Signal Detect circuit monitors the incoming optical signal level and generates a logic LOW signal when insufficient photocurrent is produced.
