Filed: 1987-07-29
Abstract: PURPOSE:To execute a stable frequency conversion without using an IF filter by a first transistor in which the two signals different in frequencies are supplied to a base and a second homopolar transistor in which an emitter is commonly connected. CONSTITUTION:Input terminals 18 and 19 are connected to each other, and the junction is connected to the base of an NPN type transistor Q2.

Title: Optical transmitter, optical communication system using the same and wavelength control method
Inventor: KUBOTA OICHI
IPC: H04J14/02
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To flexibly select the speed that changes wavelength of output light by performing change control so that a transmission signal can be practically received, following the change of wavelength of output light. SOLUTION: A transmitter side node starts to emit light in transmission start wavelength λs, waits only while other nodes can lock wavelength of a receiver in transmitting light and after that, sends ID information of self-node and a receiving end node at a transmission speed R1. At the same time, transmission wavelength is changed to long wavelength side at a wavelength change speed v1. Other nodes receiver a transmitting signal, making receiving wavelength follow the change of transmission wavelength during this time. They analyze received ID information and continue to follow it when it coincides with the ID of self-node. The transmitter side node ends the transmission of ID information, starts normal communication at a transmission speed R2 and changes transmission wavelength to long wavelength side at wavelength change speed v2 in accordance with the timing.  The receiving node continues to receive transmission content while making receiving wavelength follow the change of transmission wavelength for this time.
