Patent number: 7342884Abstract: Optical transceivers used in data communications equipment are typically bidirectional and require two-way communications in order to maintain their operability. However, in some applications such as cable television, the traffic is highly unbalanced with very high bandwidth requirements in one direction and minimal bandwidth requirements in the opposite direction. Hence for such efficient and cost effective one-way communication applications, unidirectional fiber optic transceivers are useful. There is provided here a unidirectional transceiver provided internally with a keep-alive signal generator to enable unidirectional transmissions. The keep alive signal is, for instance, idle characters for a Gigabit Ethernet communication system, or any other suitable handshake signal which provides the desired operability.Type: GrantFiled: September 26, 2002Date of Patent: March 11, 2008Assignee: Harmonic, Inc.Inventors: LiPing Chen, David Piehler, Adi Bonen, Jumin (Jerry) Liu

Publication number: 20060203862Abstract: An optical transmitter for coarse wavelength division multiplexed (CWDM) optical communication systems uses a conventional laser (e.g. laser diode) and in addition a heater element is provided thermally coupled to the laser. A thermal sensor and associated control circuit drive the heater so as to control the power consumed by the heater to assure that the laser's temperature is not lower than a predetermined minimum working temperature. When the sensed laser temperature is above this predetermined minimum temperature, the control circuit turns off the heater. The total operating range of the transmitter in terms of ambient temperature is thus extended beyond its inherent operating range by the maximum laser temperature rise created by the heater. This allows a CWDM optical transmitter with the heater and control circuitry to be used in outdoor applications where a wide ambient temperature range is required.Type: ApplicationFiled: March 10, 2005Publication date: September 14, 2006Applicant: Harmonic Inc.Inventors: Adi Bonen, Hoa Nguyen, LiPing Chen, Wei Huang

Patent number: 6490727Abstract: In hybrid fiber coaxial cable networks such as used in cable television where two-way digital communications are desired, a distributed termination system is provided. In such a system the home terminals are digital terminals, such as digital set-top boxes or cable modems using bi-directional transmission standards. The functionality of the head end controller in a conventional system is in this system distributed between the head end and the fiber nodes which link the coaxial cable and optical fiber portions of the system. Thereby the upstream detection takes place in the fiber nodes rather than in the head end by placing upstream burst receivers in the fiber nodes. Further there is a distributed method to enable this by providing synchronization and calibration control between the head end and the fiber nodes. Also, the return path is a digital return path supported by having the burst receivers located in the fiber nodes.Type: GrantFiled: October 7, 1999Date of Patent: December 3, 2002Assignee: Harmonic, Inc.Inventors: Moshe Nazarathy, Adi Bonen, Ilan Kepten, David Piehler
