Fabry-Perot laser diode receiver photodiode ASOC(R) Dual-wavelength Single-fiber Bi-directional WDM Optical Transceivers transimpedance amplifier silicon waveguide silicon-oninsulator substrate monitor photodiode pig-tailed fiber optical transmit/receive at different wavelengths BKM-2420 Family With Internal AGC Transimpedance Amplifier For 12+1dB point-to-point links at OC-3 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 OC-3 (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-fiber networks, for use in exposed locations such as street cabinets. This product summary describes transceivers that are suitable for point-to-point applications, including SONET, PDH, CSA and DLC. 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. Access networks Duplex point-to-point links on a single fiber Fiber to the curb (FTTC) Fiber to the cabinet (FTTCab) Fiber to the business or office (FTTB/FTTO) 9 mile/50 kft line extenders - single-fiber implementation for SONET OC-3 Short Reach (SR) and Intermediate Reach (IR-1 and IR-2) applications For more detailed product information or price enquiries, please contact your regional sales office or e-mail sales@bookham.com Link budget of 12+1dB at OC-3 (protected by 19dB beginning of life test) Extended link budgets for lower data rates such as 4xT1 CMI encoded channels, OC-1 PDH WDM links Optical Communication through Silicon ASOC BKM-2420 Family Members Typical values: (-40oC to +85oC) IMPORTANT NOTICE BKM-2425-A-21 BKM-2426-A-21 1310/1550nm 1550/1310nm Mean power in fiber -7dBm -7dBm Duplex sensitivity -26dBm -26dBm Protected link budget at OC-3 12+1dB 12+1dB Threshold current (Ith) @ 25oC 7 mA 13 mA Transmit/receive wavelength Bookham Technology has a policy of continuous improvement, as a result certain parameters detailed on this flyer may be subject to change without notice.
