For Optical Fiber Monitor System, Compact and High Performance OTDR Module

The MW9077A/A1 OTDR module is suitable OTDR module for opti-cal fiber monitor system. In recent years, monitoring of optical fibers is applicable to many fields, not only in maintenance of optical-com- munications network systems, but also security sensor, flood sensor and prevention of disaster, etc. The MW9077A/A1 OTDR module of- fers a compact and highly performance OTDR solution in such an optical fiber application system.

Extensive operating temperature range of –5 to +55ËšC The operation temperature of system is influenced by various envi- ronmental conditions, such as the installation place, and the objects being monitored. Moreover, the heat which the system itself gener- ates in fluents the operation temperature. Even such a operation temperature changes, it is necessary for each module that config- ured system be maintained the performance and the monitor system must be maintained the its reliability. The MW9077A/A1 OTDR mod- ule has a standardized dynamic range from –5 to +55ËšC. The moni-tor system can be got a ability of wide range temperature. When the circumference temperature conditions are severe, The MW9077A/A1 OTDR module always works at stabilized performance.

A5 size compact for optical fiber monitor system The MW9077A/A1 OTDR module inherits the technology of the MW9076 series Mini-OTDR. The event dead zone is 5 m and the back-scattered dead zone is 20 m. The dynamic ranges are 41 dB (1310 nm) and 40 dB (1550 nm). The sampling resolution is a mini- mum of 5 cm. The MW9077A/A1 is compact, it has a high perfor- mance to use the optical fiber monitor. When designing a monitor system, the space factor is important. To satisfy the system requirement in the limited space, a system de- signer investigates a system configuration from various angles, such as functions, abilities, and module size. Therefore, it is effective to use a compact module for the achievement of a system require- ments. Furthermore, using a compact module will miniaturize the whole monitor system, and it leads to a system-wide cost cut as a re- sult. The MW9077A/A1 OTDR module is a compact module less than A5 size (200 x 130 x 25 mm). Even for strict system conditions, there will still be sufficient space to install the module.

Quick data transmit by Ethernet interface and RS-232C The situation of the optical fiber monitoring is various. For example, in the case of measuring long-term change of optical fiber, the sys- tem checks optical fiber once in several hours by OTDR. In other cases of fiber monitoring, when the communication network happens to be troubled, the system check optical fiber immediately to find a fiber break point by OTDR. On the other hand, the monitoring of the optical fiber is always carried out to detect change of an optical fiber loss quickly. The MW9077A/A1 OTDR module can carry out trace sweep at intervals of about 1 second or less as well as getting smooth trace by averaging. The MW9077A/A1 OTDR module has 10 Base Ethernet interface. It can transmit the waveform data to a con- trol device at high speed. The MW9077A/A1 can carry out the mon- itor of an optical fiber without stress.
