Fabry-Perot laser diode receiver photodiode ASOC(R) Dual-wavelength Single-fibre Bi-directional WDM Optical Transceivers transimpedance amplifier silicon waveguide silicon-oninsulator substrate monitor photodiode pig-tailed fibre optical transmit/receive at different wavelengths BKM-2420 Family With Internal AGC Transimpedance Amplifier For 12+1dB point-to-point links at STM-1 1310nm Transmit 1550nm Receive 1550nm Transmit 1310nm Receive Features Uncooled operation from -40oC to +85oC Low threshold current Fabry-Perot lasers Data rates up to STM-1 (155 Mbit/s) Low profile 14-pin DIL package Wide dynamic range receiver amplifier Direct interface to limiting amplifier Designed to meet GR-468-CORE Applications Bookham Technology offers a range of ASOC optical transceivers that are designed for single-fibre networks, for use in exposed locations such as street cabinets. This product summary describes transceivers that are suitable for point-to-point applications, including SDH and PDH. A low-noise AGC transimpedance amplifier and decoupling capacitors are integrated into the package to increase the sensitivity of the receiver. The differential receiver outputs can be connected directly to a low-pass filter and limiting amplifier.
