1.0 PRODUCT OVERVIEW & FEATURES

1.1 Description

Lindsay Broadband’s LBA-2000H Series EDFA is a high-power Optical Amplifier, with touch

screen LCD. The LBA-2000H series comes in 4, 8, 16, 32 and 64 ports and is available in

output power range of 18dBm to 21dBm per port.

LBA-2000H is characterized by low noise and high linearity performance to meet the most

demanding requirements of CATV and FTTx applications. Well-designed ventilation and heat

dissipation ensure long life and reliable operation. Optional dual switching power supply

modules can be used for load sharing and redundancy. Powering can be 90 ~ 264VAC or -

48VDC. RJ45 Ethernet connection offers network management. The microprocessor software

monitors the laser working state and the Digital Panel touch screen LCD displays the operating

parameters, status and warning alarms. If at some point, the laser operating parameters deviate

from the permissible range set by the software, the microprocessor will automatically turn off the

laser power which offers protection for the laser. The LBA-2000H EDFA is compatible with any

FTTx PON Technology and offers a flexible and low-cost solution.

1.2 Features

• Multiple ports (4,8,16,32 and 64 ports), high output EDFA

• 19"standard rack mounted case

• Touch screen LCD on the front panel to monitor and set-up parameters

• 3 Optical Output Power control modes: APC, ACC or AGC

• Vary the output power of the EDFA according to your requirements

• High precision built in power meter to monitor input/output power and back reflections

• Auto output power shut off when input signal falls below threshold

• RJ45 Ethernet Port for Plug-in network management & SNMP

• The EDFA employs a high-powered infrared laser device that emits invisible light, which can permanently damage eye or skin on exposure.

• Avoid direct exposure of eyes & skin to the laser light source. Never stare directly into a fiber or at any mirror-like surface that could reflect light emitted from an un-terminated fiber. Never view an active fiber through optical instruments.

• Always ground the EDFA before turning on power (grounding resistance

should be less than 4 ohms), so as to prevent laser and user from static damage.

• To avoid damaging the touchscreen LCD, please do not tap it with anything

sharp or apply excessive pressure to it with your fingertips. It is recommended to use fingers when you use the touch screen LCD.

• Always turn the EDFA OFF prior to connecting/disconnecting input fiber. Also always terminate unused ports. Failure to do so may result in damage to the EDFA.

NO SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

5.0 INSTALLATION

5.1 Required Equipment & Tools

• Optical power meter

• Standard fiber test jumpers

• Denatured or 99% pure isopropyl alcohol and lint free fiber optic cleaning wipes

5.2 Installation of EDFA

1) Uninterrupted power supply (UPS) and an air-conditioned environment are highly

recommended for stable and long-time EDFA operation.

2) Install the EDFA in the 19” rack. Leave 1RU of space between the EDFA and other

equipment installed in the rack for proper heat dissipation. Make sure the air vents on

the bottom of the EDFA are not blocked.

3) Ensure the LBA-2000H EDFA is grounded and is mounted in a properly grounded rack,

grounding resistance should be smaller than 4Ω. Always ground the EDFA before turning

on power, so as to prevent pump, laser and user from static damage.

4) Terminate the output ports of the EDFA to prevent damage to the laser when not

connected to the system.

5) Ensure optical jumper connectors are matched properly to the device adapters. (ie.

SC/APC to SC/APC).

6) Carefully clean all the fiber optic connectors. The suggested way to clean a fiber optic

connector is to use a dedicated and dry cloth (Kimwipes ®’s fine cloth).

7) A microscope (at 100 times, 200 times) can be used to check the cleanliness of fiber

optic connector surface from any contamination or blemish.

8) Clean the EDFA connector before installing the optical test cable. 2.5 mm cleaning

swabs are available. Clean both the bulkhead and fiber connectors.

9) Measure the input optical power to the EDFA. Verify the Input optical power is in the

range of -10dBm to +10dBm. Use an optical power meter to verify that the optical input

level is within the specification. However, the Recommended Input Level to the EDFA


7 | P a g e

LBA-2000H Series

User Manual

is 0 dBm.

10) You can now connect the Optical fiber to the OPT IN connector on the Front panel. Also

connect the optical fiber(s) to the appropriate OPT OUT(s) connection. Terminate the

unused output ports with an Optical Terminator to prevent any reflections.

11) Turn ON the EDFA.

Note: Always turn the EDFA OFF prior to connecting/disconnecting input fiber. Also always terminate unused ports. Failure to do so may result in damage to the EDFA.

12) Check the LCD display & verify that the System Initialization is in process. (see figure 3)

13) Use the Optical Power meter to verify the output Optical power meets the specification.

14) There is also an Optical Test Point on the front panel of the EDFA. Its output power is -5

to +5 dBm. You can verify the EDFA amplification at the Optical test point.

Warning signs are displayed on the Touch Screen LCD interface. They are explained below.

These signs can be helpful when installing and setting up the EDFA.

LBA-2000H has built-in power meter to monitor & display the optical power to the user interface

with ±0.2dB accuracy. Detector automatically calibrates the optical power on the EDFA via the

microcontroller (MCU). When input power is greater/lower than the input power range or high

level of back reflections or if EDFA is overheating, the LBA-2000H will turn OFF the pump

current (0%) & shut down the optical output of the EDFA. Also Default factory setting for

Amplifier mode is APC mode.

Note: When entering or changing any settings on the LBA-2000H EDFA, it will ask to enter “PIN”. The

EDFA asks the user to enter PIN in order to avoid false touch and to prevent unauthorized users. See

Figure 5. Input PIN code and press “Save” to proceed. The default PIN code is “1111”, also labelled on top

of the EDFA. The default PIN authorization timeout is 5 minutes. If the user does not touch the screen

over 5 minutes, it asks for a PIN again. User can also go to Web Management to change PIN code and

PIN authorization timeout.

APC Mode (recommended): On the Setup menu page touch “APC” to enter APC mode.

Automatic Power Control (APC) mode sets the Optical Output to your requirement. Shown in

Figure 6. The set output power is maintained regardless of the variation in input power or pump

current or temperature. The EDFA automatically adjusts the pump current to ensure stable

desired output power. However, the user cannot exceed the minimum and maximum output

power specifications of the EDFA.

Using the numeric keypad, enter the value you want to set the Output Power at and hit save.

LBA-2000H Series

User Manual

Figure 6: Using APC mode

ACC Mode: On the Setup menu page touch “ACC” to enter ACC mode. See Figure 7.

Automatic Current Control (ACC) mode provides direct control to the amplification by managing

the pump current of the EDFA. The pump current stays stable irrespective of input power. The

pump current is set as a percentage (%) of the maximum value from the factory. By default, this

value is 80/80%. However, the output power cannot exceed the Critical Minimum and Maximum

specs of the EDFA. Using the numeric keypad enter the desired Pump Current value & save.

Figure 7: Using ACC Mode

AGC Mode: On the Setup menu page touch “AGC” to enter AGC mode. Shown in Figure 8.

Automatic Gain Control (AGC) mode establishes and maintains the gain of the signal regardless

of the input signal or temperature. The EDFA automatically adjusts the pump current according

to input power to maintain the required gain. However, the output power and pump current

cannot exceed its minimum and maximum rating to maintain gain. For example, the gain of

EDFA is set to 20dB, and then giving the EDFA -10 dBm input power results in output power of


12 | P a g e

LBA-2000H Series

User Manual

+10 dBm. Similarly for the same 20dB gain setting, giving the EDFA 0 dBm input power results

in +20 dBm output power. Using numeric keypad enter the value of gain and hit save.
