Fiber optic technology has become the backbone of today’s video and broadband distribution. When it comes to CATV and satellite TV networks, a CATV+IF optical transmitter and receiver system provides a powerful way to deliver high-quality signals over long distances, while keeping performance stable and deployment simple.

The Role of Optical Transmission in Modern Networks

Traditional coaxial cables face limitations in distance, bandwidth, and resistance to interference. By switching to fiber, operators and service providers gain:

• Extended reach without significant signal loss.

• Support for wide frequency ranges up to 2600 MHz.

• Immunity to external noise and EMI, ensuring consistent quality.

• Flexibility for integration in both FTTH and satellite TV environments.

This makes optical transmitter and receiver solutions essential in next-generation distribution systems.

Core Features of the Solution

Optical Transmitter (1550 nm, 3 mW Output)

• Delivers stable optical power for long-haul fiber transmission.

• Supports 47–2600 MHz frequency range, ideal for CATV and satellite IF signals.

• Compact and energy-efficient design, powered by 12VDC.

Optical Receiver with AGC

• Covers 70–2600 MHz bandwidth with excellent flatness (±2 dB).

• AGC function ensures constant RF output (84–88 dBµV), even when optical input fluctuates between -12 dBm and -2 dBm.

• Maintains high CNR and MER, guaranteeing clear video and stable broadband performance.

• Low power consumption, compact size, and user-friendly monitoring LED.

Application Scenarios

1. FTTH (Fiber to the Home)

   • Brings CATV and broadband services directly to subscribers.

   • Ensures end users enjoy strong, consistent signals with minimal maintenance.

2. Satellite TV Distribution

   • Transports satellite IF and CATV signals through a single fiber.

   • Compatible with 13/18V control and 22 kHz tone switching, widely used in satellite systems.

3. Mixed Service Networks

   • Integrates CATV, high-speed internet, and satellite broadcasting in one solution.

   • Simplifies network architecture while reducing operating costs.

Why Operators Choose CATV+IF Optical Solutions

• Wideband performance: Supports existing and future services up to 2600 MHz.

• Reliable output: AGC technology eliminates fluctuations caused by optical power variation.

• Easy integration: Compact design and SC/APC connectors ensure simple deployment.

• Future-ready investment: Flexible enough to adapt as networks expand.

Final Thoughts

For network operators, ISPs, and system integrators, a CATV+IF optical transmitter and receiver system is a proven solution for FTTH and satellite TV applications. By combining the strengths of fiber optics with smart features like AGC, it ensures high-quality service delivery, stable network performance, and a cost-effective path toward the future of broadband and broadcasting.
