PURPOSE: A visualization unit for an automatic laser interruption state in an optical transmission system and a method thereof are provided to visually notify automatic laser interruption state to an operator located where an optical fiber is cut. CONSTITUTION: It is sensed that a highly outputted main optical signal flowing through an optical fiber is interrupted(ST11). Accordingly, a highly outputted main optical signal of a transmitting terminal is interrupted(ST12). An optical switch of an ALS visualization combining part is switched from the main optical signal of the transmitting terminal to an ALS visualization light source part(ST13). An ALS visual light having regular output value is generated by driving the ALS visualization light source part and is applied to the optical fiber through the ALS visualization combining part(ST14). If the ALS visual light is reflected, an optical detecting part detects an output of the reflected ALS visual light(ST15). A signal processing part compares an output of an ALS visual light transmitted from a visual light source to the optical fiber with the detected output of the reflected ALS visual light for calculating distance to an optical fiber cut point(ST16). The signal processing part controls the visual light source for the output of the ALS visual light(ST17). If the cut optical fiber is restored(ST18), the ALS visual light of the ALS visualization light source part is interrupted(ST19). The optical switch of the ALS visualization combining part is switched to the main optical signal of the transmitting terminal(ST20). The main optical signal of the transmitting terminal is driven to perform normal optical transmission(ST21).

PURPOSE: A method for the communication of optical fiber is provided to transmit the state of an open link among the connections of multi link optical fiber to the other link while satisfying the safety standard of an OFC(Open Fiber Control). CONSTITUTION: Each link in multi links includes duplex link for selecting at least one optical relay device. Herein, the optical relay device transmits the state of one open link among the duplex links in the links of optical fiber connection. Also, the method for transmitting the state of the open link is completed by using a hybrid approaching method using an external band signal, an electric lap mode, or the external band signal and the electric lap mode. Therefore, if the original open link is closed, the state of the closed link is automatically transmitted.
37 OPTOELECTRONIC TRANSCEIVER HAVING DUAL ACCESS TO ONBOARD DIAGNOSTICS PCT/US2004021675 2004-06-30 WO2005013648A3 2005-09-15 HOSKING LUCY G; STEWART JAMES; HO ANTHONY
The optoelectronic transceiver includes first and second controller ICs. Each controller IC includes logic, a memory, an interface, and at least one input port. Each memory is configured to store digital diagnostic data and has a unique serial device address to allow a host access to each of these controller ICs separately and independently At least some of the digital diagnostic data is common to both the first controller IC and the second controller IC. The inclusion of two controller ICs allows the same diagnostic data to be stored in completely different memory mapped locations. This allows hosts that are preconfigured differently to read different memory mapped locations on the different controller ICs to obtain the same diagnostic data.
