4 Operation instructions
4.0) Boot show: Please put the plug in the
outlet with AC220V, and the LCD panel will
show “SYS_INITIALIZATTING Wait……” ,
after system initialization, the LCD panel will
show as Figure (1) in page “0”. When the
show in the LCD panel stays in the initial
image and only the “……” flickers, when the
“TEMP” light is red, it means there are some
problems in the process of initialization,
commonly temperature is quite different from
rating. (Note: If the LCD panel goes black
after it is on standby a period of time, just
click “ , ” to awaken it.)
4.1) Query the parameters of transmitters: Figure (1) in page “1”. In the current page
click the button " " to query the parameters of transmitters. As shown in Figure (2).
4.1.1) Product Type: Figure (2) in page “1.1”.
4.1.2) Product serial number: Figure (2) in page “1.2”.
4.1.3) Transmitters temperature: Figure (2) in page “1.3”.
4.1.4) fan status: Figure (2) in page “1.4”. The fan, a total of three kinds of working state can be
adopted .In the current page, click the” ” key to change the working state, while in the "AUTO"
state, when the device internal temperature is higher than 35 ℃, the SCM will automatically open
the chassis fan to cool, and it will not close until the temperature dropped to 30 ℃.

4.1.5) The current output real time optical power of equipment group: Figure (2)
in page “1.5”.
4.1.6) Laser deviation: Figure (2) in page “1.6”. Laser diode has a rated current, when
operating current is more than 130% of the rated current, the life of laser is affected, more serious,
the laser will be damaged. So when detected operating current is more than 130% of the rated
current, the hardware circuit in the equipment has limited the range.
4.1.7) Laser Temperature: Figure (2) in page “1.7”. Lasers work properly at 15 ℃ ∽ 35 ℃
temperature range. LCD displays the actual temperature of laser, such as "25.5 ℃".
4.1.8) laser cooling current: Figure (2) in page “1.8”. In order to ensure the internal
temperature of laser range from 20 ℃to 30 ℃, we should provide Thermoelectric cooling device
a certain amount of operating current.
4.1.9) Transmitters output laser wavelength: Figure (2) in page “1.9”.
4.1.A) RF level indicates: Figure (2) “1.A”. The machine default RF control mode is AGC, it
cannot be chosen. It has been set according to standard in the factory, only input to optical
transmitter a level between 75dBuV and 85dBuV (80dBuV suggested), the optical transmitter is
standard modulation meter. Lighted LCD square is about in the center point in the current page.
4.1.B) Back to front menu
4.2) Query the parameters of power: Figure (1) in page “2”. In the current page click the
button " " to query the parameters of power. As
shown in Figure (3):
The supply voltage testing the circuit
(+5V,-5V,+24V,+8V): Laser is a more expansive
device, in order to ensure it can operate safely and
reliably, the normal circuit supplied by power is a
prerequisite. So the additional
microprocessor in the machine monitors the
circuit, when detecting power is in the
normal range, the LCD displays normal
value of every power.

5 Network management applications
HFC network management system, has always been a difficulty that concerned by users and
manufacturers. Imported equipment is generally claimed with a network management system
which is based on industry standard RS232 or RJ45 interface. In order to achieve the network
management, the users need to purchase high-cost private network management software. And
each manufacturer's software is not compatible with each other. To achieve network management
is very difficult. At present there are no news reports about available network management in
Domestic system. If adopt the SNMP, the users also need to purchase specialized network
management software and there are incompatible issues between manufacturers. Many domestic
manufacturers also claim that their equipments have a network management system or are
compatible with the AM company network management system. but the device's RJ45 or RS232
interface is basically vacant and cannot achieve the network management functions.
Our company is the well-known manufacturers in the cable broadband optical transmission
system. We have been concerned about how to use the most economical and most convenient way
to achieve the network management in the cable broadband networks. Now the ESV6.0 network
management system launched by our company is a new network management concepts based on
the SNMP / TCP / IP protocol.
5.1) Interface of integrated work of the monitor server
After plugging the optional transponder, the machine has the function of network management,
just need to connect the RJ45 interface signals to the LAN, and connect to the main server from
any of the LAN Ethernet port., then set up IP addresses, according to the method in 4.A etc. so we
can monitor the machine’s running conditions at real time when the network management system
is running.

6 The notes about optical connection
6. 1) before you connect them, carefully cleaning all the fiber optic connectors and
connectors
Cleaning Guide:
6.1.1) Fiber Optic jumper
Removal the dust cap of fiber optic connector, pay attention to confirm the optical
connector is a APC surface;
The tips of cleaning fiber optic connector is to use a dedicated and dry cloth without
velveteen (the company 5Kimwipes ®’s fine cloth); In addition, preferably adopt special
microscope (at 100 times, 200 times) to check the cleanliness of fiber optic connector
surface or blemish.

10
pay attention to maintaining the fiber optic connectors is clean;
fiber optic connectors (flange) is clean;
you can use a dedicated compressed gas to clean the surface of fiber optic connector;
you can remove the dust which is less than 0.2 microns, better without residue;
hold the tank of compressed air from the connector about 6 inches, alignment flange, and
press the nozzle switch shortly times, so you can clean the connector completely;
if there is no dedicated compressed air, the 2.5 mm cotton swab for cleaning can also be
used to clean the optical transmitter connectors, or remove the flange and clean the other
side of the optical fiber jumper connector directly ;
Note: When handling fiber optic connectors must be very careful to avoid damage.
6.1.2) using the optical fiber jumper to connect the output of optical transmitter to the optical
power meter;
6.1.3) Using the optical power meter to check the output of the transmitter optical power is
within normal limits;
7 Other notes
7.1) The machine should have a good grounding, grounding resistance should be smaller
than 4Ω. According to international standards, 220Vac line adopt three-wire system, the midline is
grounding wire.
7.2) The machine should be set up in a anti-hot, anti-cold, anti-wet environment, so as to
avoid excessive temperature and humidity affect the use life of machine.
7.3) The machine adopts high-performance, highly reliable switching power supply with
constant voltage and over-current protection. In the right of switching power supply,there is 1A
imported fuse that can be work at 85Vac ~ 265Vac electrical line.
7.4) To ensure the optical return loss ≥ 45dB, this machine’s optical connectors adopt FC /
APC, other models (such as FC / PC) could not be picked. The connector should be installed to
keep clean. You should use ethanol and defatted cotton wool to wipe after plug repeatedly.
7.5) Once the laser transmitter enter the work state, because the light signal input(pump light
input) is quite high light output for pump light, the eye cannot look directly at the light input from
the back panel of the machine in order to avoid the laser beam burning the human eye retina.
