AFCT 5805AZ AFCT-5805xxxZ 155 Mb/s Single Mode Fiber Optic Transceiver for ATM, SONET OC-3/SDH STM-1 Data Sheet Description Features 1300 nm Single mode transceiver for links up to 15 General Km The AFCT-5805xxxZ transceiver is a high performance, Compliant with T1.646-1995 Broadband ISDN and cost effective module for serial optical data communica - T1E1.2/98-011R1 SONET network to customer tions applications speciefi d for a data rate of 155 Mb/s. It installation interface standards is designed to provide a SONET/SDH compliant link for Compliant with T1.105.06 SONET physical layer intermediate reach links operating at +3.3 V or +5.0 V specifications standard input voltage. Multisourced 1 x 9 pin configuration Can replace LED multisourced 1 x 9 transceivers Transmitter Section Unconditionally eyesafe laser IEC 825/CDRH Class 1 The transmitter section of the AFCT-5805xxxZ consists compliant of a 1300 nm FP laser in an eyesafe optical subassembly Integral duplex SC connector receptacle compatible (OSA) which mates to the fiber cable. The laser OSA is with TIA/EIA and IEC standards. driven by a custom IC which converts differential input RoHS compliant PECL logic signals, ECL referenced (shifted) to +3.3 V or +5 V supply, into an analog laser drive current. Two Temperature Ranges: AFCT-5805BZ/DZ 0C to +70C Receiver Section AFCT-5805AZ/CZ -40C to +85C AFCT-5805AMZ -40C to +85C The receiver utilizes an InGaAs PIN photodiode mounted AFCT-5805AEMZ -40C to +85C together with a transimpedance preamplifier IC in an OSA. Single +3.3 V or +5.0 V power supply operation This OSA is connected to a circuit providing post- amplifi - Wave solder and aqueous wash process compatible cation quantization, and optical signal detection.

Block Diagram Receiver Signal Detect Applications Information Signal Detect is a basic fiber failure indicator. This is a Typical BER Performance of Receiver versus Input Opti- single-ended PECL output. As the input optical power cal Power Level is decreased, Signal Detect will switch from high to low (deassert point) somewhere between sensitivity and The AFCT-5805xxxZ transceiver can be operated at the no light input level. As the input optical power is Bit-Error-Rate conditions other than the required BER = -10 increased from very low levels, Signal Detect will switch 1 x 10 of the ATM Forum 155.52 Mb/s Physical Layer back from low to high (assert point).
