1.0 PRODUCT SUMMARY
1.1 Product summary
The Maxcom MX-A5100 Erbium Doped Fiber Amplifier (EDFA) has been designed
for CATV, FTTH and HFC applications. The EDFA is suitable for long haul transmission
networks or FTTH distribution networks.
The MX-A5100 series is a CATV booster EDFA has a gain spectrum band within
1540~1565nm. It is designed for the application of single channel, or 1~8 continuous
ribbon channels (ITU wavelength). Typically, a fiber CATV system operates in single
wavelength that has no strict requirement on gain flatness. The MX-A5100 booster
amplifier is featured with low NF and high-saturated output power. It is applicable for
Primary Headends, Secondary Headends, Hubs, OTN’s and line relay, as well as other
optical communication networks. The MX-A5100 is applied commonly and widely
compatible with other EDFA’s and Transmitters in a CATV system.
The MX-A5100 series EDFA’s are high performance, single optical output (optional 2, 4,
8 output) EDFA’s designed for analog and digital CATV QAM signals. Maxcom’s 1550
optical amplifiers and EDFA’s adopt world class pump lasers and American OFS
erbium-doped optical fiber components. Excellent APC, ACC and ATC control, superb
design in the ventilation and heat-dissipation ensure long life and a highly reliable
operation of the pump laser.
The LCD at the front panel offers equipment status and warning alarms. The laser will
switch off automatically if optical power is lost, which offers protection for the laser.

4.0 DESCRIPTION OF STATUS ALARM
Working status indication (LED) is near the power supply switch in the front panel.
When it is green, the device is working properly; when it is red, the laser does not
operate; when it is blinking red, there is an alarm.
A. With the power supply, if the unit is operating properly, the digital panel will
display “READY: KEY OFF”and the red light will illuminate.
B. Turn on with the key, the digital panel will display “KEY OFF”. After a few seconds,
the laser is turned on automatically and the indication light turns to Green from
Red.
C. Pressing \bottom will display parameters .
D. If any fault listed above has occurred, there will be an alarm (Red light flashing),
The Microprocessor will turn off the laser automatically, and digital panel will show
the reason of the fault.
E. In order to protect the laser, the power supply of the laser has a time-delay
function. After turning on with the key, the laser will start to operate after 10
seconds.
Assembly and Power Connections
A. Equipment should be mounted in a 19-inch chassis or cabinet.
B. The optical amplifier is designed to work within the temperature range 5°C~50°C
(23°F~122°F). Maxcom suggest a target environment temperature of 25°C(77°F).
Humidity should not exceed 85%. A dust free environment is desirable, however
if dust is present, clean the fans periodically as needed to maintain good air flow
and cooling to prevent the unit from overheating.
C. The equipment may operate with AC or DC power supplies and uses optional
dual power supplies for redundancy.
D. Establish a good ground connection to the chassis. If using AC power, according
to international standards, 120VAC connections adopt three-wire systems, the
center wire is the ground.
E. Clean Optical Connectors before use.

Fiber Connections
Cleaning fiber-optic connectors can help prevent interconnect problems and
therefore, aid system performance. When optical connectors are disconnected and
reconnected, the fiber surface may become dirty or scratched. The goal of cleaning
the fiber optic connectors is to remove all dust and contaminants without leaving
any residue.
DO NOT connect or disconnect optical jumpers/connectors when unit is on and in
operation (switched on)! Connector surface may become damaged or burned by
HIGH LASER POWER Level. Unit must be switched to off position prior to any type
of connection being made to unit. In case of accidental damage where levels are
displayed normally on screen, but low on the output port, the optical connector
may be changed or replaced to restore normal levels.
CAUTION:
For high power optical levels, in particular to high power optical transmitters and
EDFA’s, extra cation should be used. Fiber connectors can be burned or melted,
arcing may occur, damage may occur to any device that a connector comes in
contact with. Extreme caution and safety practices should be observed to avoid
contact with eyes and skin. To avoid injury and microscopic damage to fiber mating
surfaces, turn off optical power before making or breaking optical connection.
