BOOKHAM ATM2400C

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
• -40°C to +85°C 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
