LC-155Axxxxxx 155Mbps 2x5 SFF LC Duplex Optical Transceiver Module for Fast Ethernet, ATM, SONET/SDH STM-1/OC-3 Features： Full Compliance with the Optical Performance Requirements of the ATM 100Mbps and 100 Base-FX Version of IEEE 802.3u. Industry Standard 2x5 Footprint and Duplex LC Connector Interface. 3.3V Power Supply. PECL Differential Inputs and Outputs. PECL（LC-155A2 Series）or TTL（LC-155A4 Series）Receiver Signal Detect Indicator. Wave Solder and Aqueous Wash Process Compatible. RoHS Compliant per Directive 2002/95/EC Description： The LC-155Axxxxxx series are 2x5 optical transceiver modules designed expressly for high-speed communication applications that require rates of up to 155Mbps. They are all compliant with the SONET/SDH standards. These PIN / Preamplifier combinations are coupled into a custom quantizer IC which provides the final pulse shaping for the logic output and the Signal Detect function. The data output is differential. The signal detect output is single-ended. The LC-155Axxxxxx transceivers are supplied in industry standard 2x5 footprint and duplex LC connector. Application： Multimode Fiber Backbone Links. The LC-155Axxxxxx series meet Class-1 eye safety standard and effective distance up to 2Km. Fast Ethernet and ATM Compatible. Multimode Fiber Media Converter. The transmitter sections utilize 1310nm Surface Emitting InGaAsP LEDs. These LEDs are packaged in the optical subassembly portion of the transmitter section. A custom silicon IC that converts differential PECL logical signals into an analog LED driving current then drive it. The receiver sections utilize InGaAs PIN photodiodes coupled into a custom silicon transimpedance preamplifier IC. These are packaged in the optical subassembly portion of receiver. www.deltaww.com DELTA ELECTRONICS, INC. 1 Aug., 2006 Rev.：0E LC-155Axxxxxx Absolute Maximum Ratings Parameter Storage Temperature Lead Soldering Temperature Lead Soldering Time Supply Voltage Symbol Ts TSOLD tSOLD VCC Min. -40 Symbol Min.
