PRODUCT SUMMARY
The Maxcom MXA54 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. This optical amplifier is packaged in a 19” rack mount housing
to provide a complete optical communications solution. Maxcom offers our MXA54 platform
which can be ordered with 8, 16, 32 and 64 output ports and various output powers.
The output power available is from 16.5 dBm to 23 dBm or may be customized.
The MXA54 series is a high-power multi-port EDFA with a gain spectrum band within
1540~1563nm. It is designed for the application of a single channel or 1~8 continuous
ribbon channels (ITU wavelengths). This series of EDFA offers a flexible and low-cost
solution for a CATV systems large coverage area.
The MXA54 series EDFA’s are a high performance, multiple optical 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 an exceptionally 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 security protection for the laser
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.

Maxcom EDFA’sare available in many configurations based on the customers
request and the requested connector types.
The drawings below illustrate the various forms and connector types. This provides
a very flexible platform to accommodate most customer requirements.

PORT AND CABLE ASSIGNMENTS
The MXA54 series provides the following management port:
RS232 port: suitable for examining the MXA54 parameters and system configuration by a
PC RS232 port.
SNMP: Simple network management protocol.
Before connecting the MXA54 series to a port, please read the following instructions and
port connectivity requirements.
Management Port (RJ-45)
Port Description
The MXA54 series management port connector type is RJ-45.
Figure 4.1.1 RJ–45 Connector Plug and Socket
The Management port (RJ-45) can be connected to any device that uses a
standard network interface (e.g., a workstation, server, bridge or router). A RJ-45
MDI may be connected with similar network equipment (such as other MXA54’s
or a network hub). Use unshielded twisted-pair (UTP) or shielded twisted-pair
(STP) cable for RJ-45 connections: 100-ohm Category 3, 4 or 5 cable for 10
Mbps connections or 100- ohm Category 5 cable for 100 Mbps connections.
Please ensure that the cable length does not exceed 100 meters.
Pin assignment
When a network management cable (RJ-45 connector on each side) connects
NMS PC and the MXA54 series directly, it should use a straight through cable. See
Figure 4.1.2.

Port Connection
The MXA54 series can automatically detect the Ethernet cable type (Straight-through or
Crossover), so either type may be used. An Ethernet twisted pair cable should be
connected between the RJ-45 connector (MDI-X) of the MXA54 series and any device
with a standard network interface (such as a workstation or server), or to a network
interconnection device (such as a bridge or router).
1) Ensure that the device to be connected has a 10BASE-T or 100BASE-TX network
interface card (NIC).
2) Prepare a twisted pair Ethernet cable with RJ-45 plugs on each end. Use Cat 3, 4
or 5 cable for standard 10Mbps Ethernet connections, or Cat 5 cable for 100Mbps
Fast Ethernet connections.

3) Plug one end of the cable into the PC's NIC and plug the other end into any RJ-45
port of the MXA54 series. All the MXA54 RJ-45 ports support both 10Mbps and
100Mbps Ethernet connections. Ensure that the plug's locking tab clicks into proper
position to make good connection.
Caution: Do not plug a phone jack connector into the RJ-45 port. This may damage
the EDFA. Instead, use only twisted-pair cables with RJ-45 connectors that conform to
FCC standards.
Note:
1) Connect other compatible MXA54 series or network hubs, use a direct or a cross
cable to connect MDI port in other devices.
2) Ensure that the twisted pair cable length does not exceed 100 meters.
3) Cat 5 cable is recommended for all network connections to avoid confusion or
inconvenience, when upgrading to Fast Ethernet devices in the future.
4) Cascade length provision: IEEE 802.3 standard prescribes that through twisted pair
at most 4 hubs (such as repeaters) may be cascaded, and IEEE 802.3u standard has
more strict order for high-speed Ethernet. So, when cascading devices except for this
MXA54 series, please follow the above connection requirements.
Connection Management (Out-Band)
Remote management may be performed through the dedicated Management port
(10/100BASE-TX port) on the front of the MXA54 or any 10/100BASE port of the
MXA54.
Before the Management port is accessed through LAN port, please configure the IP
address and subnet mask by serial port according to network configuration
requirement.

FAULT DISPOSAL
The MXA54 series FTTP EDFA can monitor system operation and offer brief notices of
warnings and can correct the majority of status deflections of the equipment, such as:
system parameter floating, equipment tolerance, laser aging, level changes, and temperature
changes. The PUMP laser will continue operating when alarming. The alarm will disappear if
the facility is self-detecting continually or the relative system parameter recovers into normal
range. Some serious warnings may be eliminated by restarting the power supply of the unit.
The warning will disappear automatically if the relative parameters recover to normal range.
Most of warnings will be sent out when the correction ability is close to or exceeds the
permitted range. For most situations, the user cannot modify the statuses.
