Description

13dBm Optical Transmitter – High-Power Fiber Optic Signal Transmission Solution

The 13dBm Optical Transmitter is a high-output, state-of-the-art optical signal transmission device specifically designed for long-distance fiber optic communications. Built for performance and durability, this transmitter ensures stable and efficient delivery of RF signals over optical fibers, making it an ideal solution for CATV networks, FTTH (Fiber to the Home) systems, and other broadband applications.

With an output power of 13dBm, it enables signal distribution over long fiber links without the need for excessive amplification. The transmitter is engineered using cutting-edge technology to ensure excellent linearity, low noise, and minimal distortion—essential features for high-fidelity analog and digital signal broadcasting.

Key Features of 13dBm Optical Transmitter

1. Powerful 13dBm Optical Output

With a high optical output of 13 decibels-milliwatts (dBm), the transmitter provides robust signal strength suitable for long-distance transmission. It reduces the need for external optical amplifiers in medium-range deployments, thus offering cost savings and simplicity in system design.

2. Stable 1550nm Wavelength Operation

Operating at the standard 1550nm wavelength, this optical transmitter ensures low transmission loss and is compatible with WDM, DWDM, and EDFA systems. The stable wavelength allows it to maintain consistent performance even under varying environmental conditions.

3. High Linearity & Low Distortion

The 13dBm Optical Transmitter delivers outstanding CNR (Carrier-to-Noise Ratio) and CTB/CSO performance, making it suitable for both analog and digital signal applications. This ensures excellent picture and sound quality in TV broadcasting and superior data transmission in broadband networks.

4. Advanced Microprocessor Control

Integrated with a smart microprocessor system, the transmitter constantly monitors key parameters such as optical power output, laser temperature, and input RF signal levels. Real-time monitoring allows users to detect faults early and maintain optimal system performance.

5. APC Connector with Low Back Reflection

Fitted with APC (Angled Physical Contact) connectors, the device minimizes back reflection, ensuring clean and uninterrupted signal transmission. The SC/APC or FC/APC interface options provide flexibility for integration into various fiber optic systems.

6. Compact & Rack-Mountable

This optical transmitter comes in a 1U standard rack-mount metal casing, making it easy to install in telecom closets, broadcast head-ends, or data centers. Its durable design ensures long-term operation with minimal maintenance.
