| Data Sheet 2.5Gb/s APD preamp Mini-DIL receiver ATM2400C This product is a high sensitivity optical receiver optimized for OC-48 optical transport systems. The high sensitivity performance given by the avalanche photodiode (APD) and preamp make the product ideal for maximizing unamplified transmission distances. The receiver supports FEC data rates up to 2.7Gb/s. The DC component cancellation function offered by the preamp allows the product to operate error free under high input power conditions. The receiver contains an APD, a low noise preamplifier, a precision thermistor and a single-mode connectorized fiber pigtail, all housed in an industry-standard Mini-DIL package. Features: * High sensitivity, -34dBm typical * Better than 0dBm overload * Industry-standard Mini-DIL package footprint * Differential data outputs * -40C to +85C maximum operating temperature range * RoHS 5/6 compliant Applications: * OC-48 Optical transport Systems * OC-48 DWDM Metro and Long Haul Systems * STM-16 SDH or OC-48 SONET Systems 1 Data Sheet Operating characteristics All parameters are measured with outputs 50 Ohm AC coupled, specified at a case temperature of 25C unless otherwise stated. Optical wavelength between 1525-1575nm. Data to 1610nm available on request.
