Présentation du produit
PL3100A Broadband Amplifier is a 1GHz bandwidth two-way amplifier. It is designed specifically for use in fiber deeper cable TV networks. PL3100A Broadband Amplifier has two high level RF outputs in only main portsoutput mode, that can be split into four low level outputs in main and aux ports output mode. PL3100A Broadband Amplifier has GaAs technology in use, that guarantees the highest CTB and CSO performance.
PL3100A Broadband Amplifier’s adjustments of output level and slope are made using standard JXP PADs to minimize spare parts. AC shunt power directors located near the ports. These power directors are used to direct AC current to/from the amplifier input and output ports. AC circuitry provides 10A of steady state current capability that is able to with stand 15A of peak current (maximum 2 hours at 60Cº).
PL3100A Broadband Amplifier can be field upgradable to an Optical Node.

PL3100A: 1GHz High-Output Outdoor Broadband Amplifier (GaAs Tech)
A high-performance two-way amplifier designed for fiber-deep HFC networks, offering modular scalability and superior distortion performance.
- Advanced GaAs Gain Stages: Le PL3100A broadband amplifier leverages Gallium Arsenide (GaAs) technology to deliver high output levels (up to 110dBµV) while maintaining ultra-low CTB and CSO distortion, essential for digital and analog mixed-channel loading.
- Scalable Port Architecture: Designed for flexibility, it operates as a high-level 2-output amplifier or can be split into a 4-output configuration. This allows network engineers to optimize signal distribution based on specific neighborhood density.
- High Upgradability: Unique modular internal design allows the PL3100A to be field-upgraded to an Optical Node, protecting your infrastructure investment as your network transitions from HFC to FTTH/Deep-Fiber.
- Power Handling: Features AC shunt power directors capable of 10A steady-state and 15A peak current, ensuring reliable operation in line-powered cable plants even during high-demand periods.
- Simplified Field Maintenance: Utilise les normes JXP-style plug-in PADs for attenuation and tilt adjustments, significantly reducing the variety of spare parts required for field technicians.
Technical FAQ: PL3100A Broadband Amplifier
Q1: How does the PL3100A handle extreme outdoor environments?
UN: Le PL3100A broadband amplifier is housed in an IP68-rated strand-mount enclosure. It includes built-in thermal compensation circuitry and ±6kV surge protection (IEEE C62.41), ensuring stable gain and hardware integrity from -40°C to +60°C.
Q2: Can the frequency split be customized for different regional standards?
UN: Yes. While the standard forward path is 54-1002MHz and return path is 5-42MHz, the PL3100A can be built with different frequency splits to comply with various international CATV standards, ensuring seamless integration into any global HFC networks.
Q3: What is the benefit of the MGC (Manual Gain Control) mode?
UN: MGC mode allows for precise manual balancing of the broadband amplifier during installation. By using plug-in attenuators, technicians can lock in the exact gain and slope required to compensate for cable loss, preventing over-driving of downstream equipment.
