Description

The ROF High-Precision EA/DFB Laser Module is an advanced optoelectronic device manufactured by Beijing Rofea Optoelectronics Co., Ltd. It features a Distributed Feedback (DFB) laser with customizable wavelengths ranging from 852nm to 2000nm and high output power options. The laser has a narrow linewidth, which can be less than 10MHz, 1MHz, or 200KHz depending on the user's requirement. With built-in optical isolation, the module offers multiple operating modes, including continuous wave (CW), internal modulation, and external signal modulation.

Available in both module and desktop packaging, this DFB laser module is ideal for applications in laser distance measurement, seed light sourcing, optical fiber communication, and optical sensing systems. It ensures high stability and precision, making it suitable for demanding applications. The output optical fiber is available in SMF/PMF, and the user can specify the optical connector type (FC/PC or FC/APC).

Frequently Asked Questions

What is the ROF-DML series of analog broadband direct light transmission modules?

The ROF-DML series are analog broadband direct-tuning transmitters that use a highly linear microwave direct-coupled DFB laser. They operate in a fully transparent mode without RF drive amplifiers and include integrated automatic power control (APC) and automatic temperature control (ATC) circuits. These modules can transmit up to 18 GHz of microwave RF signals over long distances with high bandwidth and flat response.

What are the key features of the ROF-DML series?

Key features include excellent RF response flatness, wide dynamic range, compatibility with various signal coding communication standards and network protocols, wavelength options including 1550 nm DWDM, integrated automatic power and temperature control circuits, and flexibility due to the absence of built-in RF drive amplifiers.

What applications are suitable for the ROF-DML series?

The ROF-DML series is suitable for applications such as remote antenna systems, long-distance analog optical fiber communication, military three-wave communication, tracking telemetry and control, delay lines, and phased array systems.

What are the optical characteristics of the ROF-DML series?

The optical characteristics include a DFB laser type, operating wavelength range of 1530-1570 nm with DWDM optional, equivalent noise intensity of -145 dB/Hz, SMSR of 35-45 dB, light isolation of 30 dB, output light power of 10 mW, light return loss of 50 dB, and use of SMF-28E optical fiber with an FC/APC connector.

What are the RF characteristics of the ROF-DML series?

The RF characteristics include operating frequencies of 0.1-6 GHz, 0.1-10 GHz, and 0.1-18 GHz at -3 dB, input RF range of -60 to 20 dBm, input 1 dB compression point of 15 dBm, in-band flatness of -1.5 to +1.5 dB, standing wave ratio of 1.5, RF reflection loss of -10 dB, and input/output impedance of 50 Ω with an SMA-F RF connector.

What are the power supply requirements for the ROF-DML series?

The power supply requirements are a DC voltage of +5 V and -5 V with a power consumption of 10 W.
