L-Band Wideband Fiber Transmitter Redefines Long-Distance RF Signal Transmission
The new L-Band/Wideband RF-over-Fiber transmitter module from Telemeter Electronic extends performance limits for professional signal distribution. By converting high-frequency inputs ranging from diverse sources into optical outputs, it enables robust uplink and downlink paths across several kilometers of fiber. Its sturdy construction and well-defined interfaces cater to satellite earth station and teleport operators who demand uncompromised signal fidelity. Scalable deployment supports network growth with minimal signal loss and consistent performance.
Modular transmitter processes 50 MHz to 3 GHz signals
With a modular design, the transmitter processes RF signals spanning 50 MHz to 3 GHz, surpassing standard L-band offerings to support a wider range of applications. Available in single-channel or dual-channel formats, it adapts to different operational requirements. Each input includes a selectable LNB power feed delivering either 13 V or 18 V DC, allowing direct powering of connected low-noise block converters or similar devices, eliminating the need for extra power injectors.
Offers Manual Or Automatic Gain Control Up To 30dB
The fiber optic transmitter module features a precise gain control system enabling manual adjustment from 0 to +30 dB or automatic operation via AGC. An RF monitoring port on the front panel allows instantaneous power measurements without interrupting the signal path, facilitating rapid level checks during installation. By combining flexible gain settings with non-invasive monitoring, the module maintains optimal signal integrity and low noise, supporting reliable long-distance RF transmission in applications.
1310nm DFB lasers provide CWDM/DWDM multiplexing for forty channels
By default, the system employs 1310 nm DFB lasers, ensuring stable continuous-wave operation and output. When higher channel density is required, it can be reconfigured to support both CWDM and DWDM schemes, accommodating up to forty distinct wavelengths. This multiplexing capability enables the transmission of data streams simultaneously over a single fiber link. As a result, network architects can deploy highly efficient and scalable topologies optimized for future bandwidth growth.
Remote RF Input, Temperature, Laser Status Monitoring via SNMP
Monitoring critical operating parametersâincluding RF input power levels, temperature metrics, and laser statusâis achievable through remote management via SNMP or a web interface. The in-band monitoring capability embeds these telemetry streams directly within the optical signal, transmitting health and performance data alongside the main RF-over-fiber link. This design removes the need for additional cabling, reduces installation complexity, and provides uninterrupted, real-time visibility into system health without compromising signal integrity.
Antenna-mounted L-Band modules provide kilometer-scale lossless RF signal transmission
These modules are commonly deployed in satellite ground stations and teleports to facilitate lossless transmission of L-band signals over distances ranging from several hundred meters up to multiple kilometers. Installed directly at the antenna feed or local hub, they convert and transport RF signals via fiber optic lines into central technical facilities. The robust design ensures minimal signal attenuation and maintains high phase and amplitude stability for downstream processing in control rooms.
