LC-155Bxxxx 155Mbps, SFF LC Duplex Optical Transceiver Module for Fast Ethernet, ATM, SONET/SDH STM-1/OC-3 Features： z Full Compliance with the Optical Performance Requirements of the ATM 100Mbps and 100 Base-FX Version of IEEE 802.3u. z Multisource 2x5 package styles with LC Receptacle. z Single 5V（LC-155B1 and LC-155B3 Series）or 3.3V（LC-155B2 and LC-155B4 Series）Power Supply. z PECL Differential Inputs and Outputs. z PECL（LC-155B1 and LC-155B2 Series） or TTL（LC-155B3 and LC-155B4 Series） Receiver Signal Detect Indicator. z Wave Solder and Aqueous Wash Process Compatible. Description： 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. The LC-155Bxxxx series from DELTA are SFF （Small Form Factor） 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-155Bxxxx transceivers are supplied in 2x5 DIP package style with duplex LC connector and are fully complaint with SFF Multi Source Agreement （MSA）. Application： All LC-155Bxxxx series can meet Class-1 eye safety standard and effective distance depends on ITU-T G.957 standard or power penalty. The transmitter sections utilize 1310nm Edge Emitting InGaAsP Laser Diode. This Laser Diode is packaged in the optical subassembly portion of the transmitter section. A custom silicon IC that converts differential PECL logical signals into an analog LD driving current then drive it. z Single-mode Fiber Backbone Links. z Fast Ethernet and ATM Compatible. z Single-mode Fiber Media Converter. www.deltaww.com DELTA ELECTRONICS, INC. 1 September 23, 2004 Revision：03 LC-155Bxxxx Absolute Maximum Ratings Parameter Storage Temperature Supply Voltage Symbol Ts VCC Min. -40 0 Typ.
