8.1 The machine should have a good grounding, grounding resistance should be <4Ω. According

to international standards, 220V use three-wire system into the line, middle line is the grounding

wire.

8.2 This machine uses imported high-performance, highly reliable switching power supply with

constant voltage over-current protection, which already have imported fuse can be 165V ~ 260V

voltage range of the city within the network work properly. The machine's microprocessor output

DC voltage of the monitors, if the fuse blew, indicating failures have occurred inside the machine.

Therefore, the back panel of this machine has no 220V fuse.(The same as the imported

equipment).

8.3 In order to ensure the optical return loss ≥ 45dB, this machine optical connectors uses

SC/APC & SC/UPC.Connecting joints should be maintained clean. Plug should be used after

repeated ethanol and cotton wool to wipe the optical connector.

8.4 The input optical power of optical amplifier affect the system's CNR, in practice, should be

based on indicators system, reference to " CNR degradation of the table " design the input optical

power of amplifier.

8.5 Optical fiber amplifiers work in the 1550nm wavelength, the max output optical power ≤

500mW. Access system in the machine, or optical output port unprotected pre-sets should not

open so as to avoid burns due to the optical connector, but also should prevent the laser direct the

human body, especially the eyes, causing harm to the people.

9. GUARANTEE AND MAINTENANCE MATTERS

9.1 Each optical transmitter has the company serial number (bar code). To the date of sale can

provide one-year.

9.2 The machine's microprocessor software with the laser working condition monitoring, digital

panel displays, fault alarm, network management functions. Non-human factors that can not be

damaged laser. If the machine flashes a red light appears (hint alarms), should be sent to the

company warranty. Users shall not open the lid for maintenance, otherwise the warranty

period,repairs and materials should be charged.

9.3 The warranty expires, providing life-long maintenance and equipment upgrades.

9.4 Due to power supply and man-made failures, resulting in damage to the device, are required to

collect materials costs.
