1.0 PRODUCT OVERVIEW & FEATURES
1.1 Description
Lindsay Broadband LB-1310TC series of 1RU rack mount optical transmitters are high linearity,
low noise 1310 nm high performance direct modulated DFB optical transmitters. The LB-
1310TC use high performance DFB direct modulated lasers, with single optical output powers
from 4mw to 20mw, in 2mw steps. RF broadband input (47 – 1000MHz) is directly modulated
into 1310 nm DFB laser via pre-distortion circuit for optimum distortion and noise performance.
Auto output laser power stability control (APC) and auto laser temperature control (ATC) are
standard features. The LCD front panel display is used to monitor all functional transmitter
parameters; output laser power, laser temperature, laser bias current, cooling current, power
supply voltages, MGC/AGC state and OMI value. The LB1310TC is equipped with an RJ45
communication interfaces for system network management. Optional redundant power supply
module is available upon request.
1.2 Features
1RU standard rack mounted case
High performance DFB laser with narrow spectrum and good linearity.
1310 ± 20 nm wavelength
Available Output power (4mw to 20mw in 2mw steps)
47 – 1000MHz RF input with AGC
100 – 260 VAC (50 to 60Hz) powering
APC and ATC control circuits
Built-in Microprocessor monitors laser performance
Front panel LCD display, displays all functioning parameters

2.0 SAFETY NOTES
NO SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
•The LB1310TC 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 transmitter before turning on power (grounding
resistance should be less than 4 ohms), so as to prevent laser and user
from static damage.

5.0 FRONT & REAR PANEL DESCRIPTION
The front panel display allows you to monitor the transmitter parameter; (ie. output laser power
(mw), the laser bias current (mA), temperature (℃), cooling current (mA), and RF Level) and
power supply parameters of +24V, +5V, and -5V.
At this point check the parameters using the Menu Button.
Menu Buttons：When the menu buttons “ENT” is pushed, it will show the various menu options
to choose from. After a period of inactivity (approx. 30 seconds) the backlight display will shut
off and directed to Home Screen. Push the “ , ” menu buttons to browse through or change
the transmitter parameters. Press “ENT” menu button to select any parameter or enter any
menu/sub-menu. Press “ESC” menu button to exit out of any parameter or menu/sub-menu.

6.0 INSTALLATION
6.1 Required Equipment & Tools
Digital multimeter
Optical power meter
Cable TV RF meter or spectrum analyzer
Standard fiber test jumper
Denatured or 99% pure isopropyl alcohol and lint free fiber optic cleaning wipes
6.2 Installation of Transmitter
1) Installation of the LB-1310TC should be in a controlled environmental Hub or Closure to
avoid excessive temperature and humidity.
2) UPS power supply and an air conditioned environment are highly recommended for
stable and long-time transmitter operation.
3) Install the transmitter in the 19” rack. Leave ½ inch of space between the transmitter and
other equipment installed in the rack for proper heat dissipation.
4) Ensure the LB-1310TC is grounded and is mounted in a properly grounded rack,
grounding resistance should be smaller than 4Ω. Always ground the transmitter before
turning on power, so as to prevent laser and user from static damage.
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 of cleaning 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 LB-1310TC connector before installing the optical test cable. 2.5 mm cleaning
swabs are available. Connect the fiber to the LB-1310TC.
9) Using a digital multi-meter, verify the input voltage is in accordance with power
requirements. Then turn on power.

10) Checking the LCD display verify that the System Initialization is in process.
11) After initialization press the “ENTER” menu buttons to query the parameters of the
transmitter.
12)Connect the fiber test cable and optical power meter to the transmitters optical output.
Measure the optical output power and confirm it is the same or close to the value
displayed on the LCD display. Ensure the optical power meter is set for 1310 nm
wavelength and that the fiber test jumper is clean.
13) Again, Clean the LB-1310TC connector before installing the optical cable. 2.5 mm
cleaning swabs are available. Connect the fiber to the LB-1310TC.
14) Measure the input RF signal level with a Signal level meter or a spectrum analyzer.
Make sure the RF signal level is in the range of 15 dBmV and 25 dBmV (Optimum value
is 20 dBmV). You can now connect the RF signal to the RF signal input port of the
equipment. With the proper RF signal input the Laser LED lamp will turn from Red to
Green.
15) RF AGC/MGC: Follow the RF menu to adjust the RF attenuation if required. It is
recommended to put the transmitter into Automatic Gain Control (AGC) mode. Test point
is -20 dB below the RF input level.
16) The OMI (Optical Modulation Index) is factory set for 3.5% OMI based on 79 NTSC
channels and digital channels 6db level offset above 550MHz. This adjustment should
not be touched unless done in a laboratory environment with proper equipment to
measure OMI.
