Firecomms launches 530nm long-reach RedLink transmitter for 1Mb applications over 200m of POF

Firecomms Ltd of Cork, Ireland and Tongxiang, China, which manufactures fiber-optic solutions and optical transceivers, has announced availability of its 530nm DC-1Mb RedLink transmitter for applications requiring extended link lengths over plastic optical fiber (POF).

Operating in the green spectrum at 530nm, the FT01MHNG exploits one of the lower attenuation windows of POF. At 0.1dB/m, the attenuation of the FT01MHNG is considerably lower than that of traditional POF transmitters that operate in the red spectrum, Firecomms claims, with attenuation of about 0.2dB/m. These characteristics make it possible to implement POF links up to 150m or even 200m, where traditionally link lengths have been limited to 50m.

Suited for sensing, CANbus/RS485/RS232 links, gaming, smart meter or other industrial command and control applications, the FT01MHNG transmitter opens up new possibilities for the equipment designer to replace more expensive silica-based solutions with POF, remove repeaters which are no longer needed, and implement new designs requiring galvanic or optical isolation where costs or distances have been previously prohibitive, says Firecomms.

Firecomms has been developing resonant-cavity LEDs (RCLEDs) for the past decade, says chief technology officer John Lambkin. “This announcement of a 530nm-based transmitter using extremely rugged InGaN semiconductors is another example of Firecomms’ commitment to innovation and investment in our RedLink product line,” he adds.

Firecomms has now completed full qualification of these devices, verifying how the wavelength and output power remain stable over the entire industrial temperature range of -40°C to +85°C, and demonstrating their suitability for the most demanding applications.

Link tests performed using the new transmitter with Firecomms’ FR01MHIR receiver have demonstrated transmission distances of up to 200m (depending on actual throughput).

The FT01MHNG transmitter is available for sampling through Firecomms’ sales offices and distribution channels.
