SUGAR LAND, Texas -- Applied Optoelectronics, Inc. (AOI), a leading manufacturer of laser diodes, photodetectors, and optical modules for fiber optic communications systems, introduces a family of new small-form-factor pluggable (SFP) optical transceivers with industrial operating temperature range.

The transceivers operate up to 4.5 Gigabits per second, and are designed to meet the wavelength specifications required in coarse wavelength division multiplexed (CWDM) networks over their entire operating temperature range, extending from -40 °C to +85 °C.

Most currently available CWDM SFP modules operate over a temperature range from -10 to +70 °C. A combination of unique uncooled laser chip design and an optimized module design enables this significant advance in transceiver technology.

“Minimizing wavelength drift in the new family of CWDM transceivers was a significant challenge, and AOI’s combination of chip and module capabilities enabled this latest enhancement of our SFP product line,” comments Dr. Chau-Hong Kuo, AOI’s Product Manager for transceiver products. “The enhanced operating temperature range CWDM transceivers add to our industry-leading suite of robust, highly reliable products for demanding applications.”
