LBVM920 Series 1.2 GHz Indoor High Output Optical Node
Installation & Operation Manual
PRODUCT OVERVIEW
•
Model: LBVM920
•
Bandwidth: 5-85 MHz/102-1218 MHz
•
Powering: 12-30 VDC
The LBVM920 85/102 high output optical node is designed for various applications from HFC to advanced fiber deep architecture networks. The LBVM920 node
features a 1218 MHz bandwidth, high RF output level up to 50 dBmV at 1218 MHz, 85/102 MHz split, Automatic Gain Control (AGC), and a wide selection of return
lasers including CWDM wavelengths as an option to overcome fiber limitations in a network for two-way services. All of these features and flexibility are packaged in a
compact, diecast aluminum housing.
