1.0 PRODUCT OVERVIEW AND FEATURES
1.1 Description
Lindsay Broadband LB-1000-RR series is a family of CATV Return Path Receiver Module,
converting upstream optical signal into RF signal at the headend or remote hubs. LB-1000-RR
return receiver incorporates a low noise PIN detector and RF amplifier chain. Internal selectable
RF attenuators can be switched in or out to enable each receiver to handle a very wide range of
optical input signals. Module parameters can be monitored and configured through the LB-1000-
CM system management module using the touch screen or by using the PC (Web GUI or SNMP
agent).
1.2 Features
•Four independent return path receivers in a single module
•Hot-swappable capability
•Bandwidth 5~205 MHz
•-18 to +1dBm: Standard RRx Input Range; -27 to -13dBm: RFoG RRx Input Range
•Optical AGC and MGC mode for Standard RRx, Only MGC mode for RFoG RRx
•High Output level (30dBmV) with low noise
•RF output disabled automatically when no optical signal detected, and each independent
channel can also be disabled manually using LB-1000-CM
•Manual attenuation control for each RF port
•RF output test point
•Can monitor and configure functioning parameters using LB-1000-CM

2.0 SAFETY NOTES
Failure to comply with these safety precautions and with the general or specific safety precautions
described elsewhere in the LB-1000 series manual violates the safety standards of the design,
manufacture, and intended use of the device. Lindsay Broadband Inc. assumes no liability for the
customer’s failure to comply with these precautions.
•Invisible optical radiation is emitted from fiber optic connectors which connects to this LB-
1000-RR, exposure can cause permanent injury to eyes.
•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.
CAUTION: 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 using
the touch screen LCD.
CAUTION: Do not operate the chassis outside of its maximum ratings. Doing so may result in
unsatisfactory performance, unit failure, shortened unit life span, or a safety hazard.
NO SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

4.0 INSTALLATION
Application modules of LB-1000 can be installed in any of the general slots of the rack. Module is
inserted into the rack from the front part.
1) Gently insert the LB-1000 application module into any general slot (labelled 01 to 18)
from the front of the chassis. Be careful to align the metal guide rails on the top and
bottom of the module to the chassis housing.
2) Using the handle completely push the application module into the slot. Once the
module is completely inserted into the slot, the latch on the bottom of the module will
lock into place with the LB-1000 chassis securing the module in the rack. Ensure that
the application module is securely connected to the LB-1000-CH rear panel and F-
connectors. The application module will be automatically power “ON”. The Status LED
on the front of the module will turn ON and the module will show up on the control
module screen or web interface.
Figure 3: LB-1000 application module installation
3) If the module hasn’t been properly connected to the LB-1000-CH it will not power up
and status LED will be OFF. In such a case, remove the application module from LB-
1000-CH slot and reinsert carefully as described in steps 1 and 2 above. See below
step for safely removing the module.
4) To remove the application module from the slot, press down on the latch located in the
bottom front of the module. The application module will unlock from the LB-1000-CH
rack and the module can be removed.

5) Connect the RF cable to the appropriate RF output connectors on the rear panel of
the LB-1000-CH.
6) Carefully clean all the fiber optic connectors and jumper cables. Use appropriate
cleaning swabs for fiber optic cables and connectors. Check for contamination/blemish
on the fiber cable and connector with a fiber inspecting microscope. Ensure the fiber
optic connectors and jumper cables are clean.
7) Ensure optical jumper connectors are matched properly to the device adapters. (i.e.
SC/APC to SC/APC). Using mismatched connectors will damage the connectors and
degrade system performance. Ensure that each fiber has a matching connector.
8) Use an optical power meter to verify that the optical input power level to the receiver
is within the specification (-18 to +1dBm for Standard receiver; or -27 to -13dBm for
RFoG receiver). Connect the Optical fiber to the OPT IN connector on the front panel.
9) Using the touch screen or web interface via LB-1000-CM the operating parameters for
the application module can be monitored and adjusted. Operating parameters and
adjustments on the LB-1000-RR are explained in Section 5.
