1.0 PRODUCT OVERVIEW & FEATURES

1.1 Description

Lindsay Broadband LB5155D series of rack mount Erbium Doped Fiber Amplifiers (EDFA) are

high linearity, low noise, Optical Amplifiers with single Optical output and Output power from

14dBm to 24dBm, in 1dBm steps. The LB5155D series provide a thermoelectric cooled DFB

laser with optical isolation on the input and output for stable, low noise operation. Auto output

power stability control (APC) and auto temperature control (ATC) are standard features. The

LCD front panel display is used to provide monitoring and associated alarms for all vital

parameters. If the EDFA operating parameters deviate from the permissible range set by the

software, the micro-processor will alarm the user through the LCD display and the warning

LED’s will start flickering RED with buzzer sound. The LB5155D is equipped with RJ45 and

RS232 communication interfaces for system network management. Powering is 110V – 240VAC

or 40 – 72VDC.

1.2 Features

• 19"standard rack mounted case

• Input / Output Optical Isolators provide low Noise Figure (<5.0db).

• -3 to +10 dBm input power range.

• 110 – 240VAC (50 to 60Hz) powering and 40 – 72VDC powering

• APC and ATC control circuits

• Built-in Microprocessor monitors laser and RF performance

• Front panel LED display, displays all functioning parameters

• RJ45 & RS-232 Port for Plug-in network management

2.0 SAFETY NOTES

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

• The EDFA employs an infrared laser device that emits invisible light, which can permanently damage the retina of an eye.

• Avoid direct exposure 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.

3.0 LB5155D SERIES FRONT PANEL AND BACK PANEL LAYOUT

The LCD front panel display allows you to monitor the EDFA’s parameter; i.e. Input/output laser

power (dBm), the laser’s bias current (mA), temperature (℃), and cooling current (mA).

Check the parameters using the Menu Buttons.

The DC Power Module has a three screw terminal strip to the 48VDC. Fuse replacement

should always be with the same type fuse; Cartridge type F3AL250V", 3 amp, 250V

6.0 INSTALLATION

6.1 Required Equipment & Tools

• Optical power meter

• Standard fiber test jumper

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

6.2 Installation of EDFA

1) UPS power supply and an air conditioned environment are highly recommended for

stable and long-time EDFA operation.

2) Install the EDFA in the 19” rack. Leave ½ inch of space between the EDFA and other

equipment installed in the rack for proper heat dissipation.

3) Ensure the LB5155D 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 laser and user from static damage.

4) Terminate the output port 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 -3 to +10dBm. Use an optical power meter to verify that the optical input level is

within the specification.

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

11) Turn ON the EDFA & check the LCD display to verify that the System Initialization is in

process.

12) Remove terminator from the optical output and connect the optical fiber to the OPT OUT

connector.

Note: Always have the power turned OFF when the EDFA input/output are not connected

or properly terminate unused ports so as to prevent damage to the laser.

7.0 OPERATION AND MENU FUNCTIONS

7.1 Start Up & System Initialization

Power up device, the LCD panel after loading will show “LB5155D-xx” (xx is the output power in

dBm). You then can use the Menu buttons to navigate through the different menus. There are 6

menus that you can use to monitor the EDFA parameters, and adjust some parameters. See

Figure 2.

version, Serial Number of the EDFA, System

Temperature & Network Configuration.

7.3 Optical Menu

Optical Menu is to monitor Input & Output

Power optical parameters. There is also a

setting to change the Optical Output power

called “Power Adj.” that can adjust the power

by 5dB. For example for 24 dBm Output EDFA

the Power can be adjusted from 19.5dBm to

24.5dBm in 0.1 dB steps.

Press ENT on Power Adj menu & Up/Down

arrow keys to change value and then again

press select to confirm.
