The Agilent 86106A is a 980-1625 nm (9/125 ??m) Plug-in module for 86100 Infiniium DCA Module incorporates a 10 Gb/s optical reference receiver and a 40 GHz electrical channel. The electrical channel also has a reduced bandwidth setting of 18 GHz for improved noise performance. It includes a reference receiver path for 10 Gb/s transmitter test that has been designed to meet 0C-192/STM-64 standards. It utilizes a switchable reference filter for transceiver compliance testing at OC-192/STM-64 (4th or 5th order filtering). Option 101,OC-192/STM-64 (9952 Gb/s) Fourth Order. Option 102, OC-192/STM-64 (9952 Gb/s) Fifth Order.
