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.
