Telemeter Electronic Unveils Modular L-Band RF-to-Fiber Converter Module Solution
The new L-Band/Wideband fiber-optic transmitter from Telemeter Electronic converts RF signals from 50 MHz to 3 GHz into optical signals for seamless lossless RF-over-fiber transmission. Designed for uplink and downlink use in satellite ground stations and teleports, it offers a modular single or dual-channel architecture, switchable 13/18 V LNB power, manual gain control, and precise automatic gain regulation. Optional CWDM/DWDM multiplexing and in-band monitoring ensure optimized performance over extended distances.
Modular one- and two-channel module covers L-Band to 3 GHz
Engineered as a modular unit available in single- or dual-channel configurations, the system handles high-frequency signals spanning the full L-Band spectrum and extending up to 3 GHz. Its scalable design supports seamless integration into diverse network topologies, facilitating tailored signal transmission distances and customized deployment footprints. By combining interchangeable modules with user-selectable channel counts, the solution delivers optimal performance across varying link lengths and constraints while simplifying maintenance and system expansion.
Switchable 13V/18V LNB Power Streamlines Remote Antenna Site Installation
Each RF input is equipped with a selectable DC supply of either 13 V or 18 V for powering LNBs, allowing direct feed of connected low-noise blocks or devices without requiring additional external power sources. This feature simplifies installation and reduces cable clutter at remote antenna sites where access to separate power supplies may be limited. The built-in voltage switching capability supports deployment scenarios and enhances system reliability by streamlining power distribution.
0-30dB Manual Or AGC Gain Control Front HF Monitoring
For precise signal management, gain adjustment can be performed manually from 0 to +30 dB or automatically using AGC. This versatile arrangement allows operators to fine-tune performance under varying input conditions and ensures stable output levels without distortion. Additionally, a dedicated front-panel RF monitoring port provides convenient, real-time measurement capabilities without disrupting the primary signal path. Technicians can quickly verify levels and system integrity, enhancing maintenance efficiency, minimizing operational interruptions.
1310 nm DFB Lasers Equipped Module Offers CWDM DWDM Multiplexing
By default, the transmitter module integrates high 1310 nm DFB laser diodes to ensure robust optical signal generation. As an option, users can configure the system for Coarse Wavelength Division Multiplexing or Dense Wavelength Division Multiplexing, enabling up to forty channels over a single fiber. This flexibility maximizes the utilization of existing fiber infrastructure, reduces deployment costs, and facilitates scalable expansion of communication networks by leveraging efficient channel aggregation capabilities.
Remotely Monitor RF Power, Temperature, Laser Status Using SNMP
Remote monitoring of critical operating parameters, such as RF input power, temperature, and laser status, is supported through both a web interface and SNMP. This functionality enhances secure system maintenance by delivering real-time visibility into performance metrics from remote sites. Furthermore, in-band monitoring transmits critical diagnostic data directly over the existing fiber link, eliminating the requirement for additional cabling and enabling unified communication of operational status without dedicated data channels.
Fiber-Optic Module Delivers Lossless L-Band Signal Transmission Over Distance
In satellite ground stations, the RF-over-fiber transmitter module is installed at the antenna, converting received L-Band signals into optical signals for lossless transport over fiber links spanning hundreds of meters or kilometers. This approach minimizes signal degradation, shields the transmission path from electromagnetic interference, and reduces the need for amplification. By preserving spectral fidelity, the system ensures signal integrity before it arrives in the central equipment room for further processing.
This L-Band and wideband fiber-optic transmitter module from Telemeter Electronic delivers a modular design allowing scalable deployment, precise manual and automatic gain adjustments, and flexible optical interfaces to support professional RF-over-fiber networks. Equipped with optional coarse and dense WDM multiplexing and selectable 13V or 18V LNB feeds, it also incorporates in-band system monitoring over the fiber link to provide real-time performance data and ensure reliable signal distribution across extensive distances.
