Good day!
Optical power meter: It is used to test the actually received optical power, and receiver sensitivity of the optical interfaces.
Optical attenuator: It is used to attenuate strong optical power received at optical interfaces to prevent damage to the optical interface.
Laptop: It must be installed with the U2000 LCT or U2000 for the per-NE commissioning. In addition, it is also used to test the Ethernet indexes.
Fiber jumper: It is used to connect an optical interface to the ODF, or to perform a self-loop at the optical interface board.
SDH analyzer: It is used to Testing multiplex section switching time, and frequency deviation and jitter at optical or electrical interfaces of SDH services.
Multimeter: It is used to test voltage, resistance, and current intensity.
BER tester: It is used to test bit errors at electrical interfaces.
fiber connector: It is used to connect two fiber ends, or to connect one fiber end to a light source or detector.
Network cable: It is used to connect an NE to a PC, or to test the Ethernet service channels.
