AOI Introduces Wide-Temperature-Range High-Speed Optical Transceiver for CWDM

Applied Optoelectronics 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.”

Like many of AOI’s SFP products, the newly released modules offer:

• Hot pluggable SFP Multi-Source Agreement compliant
• Serial ID functionality support
• FC-PI 13.0 compliant
• Digital diagnostic SFF-8472 compliant
• Meets GR 468 reliability specifications

The new transceivers are offered at all wavelengths specified in the ITU-standard CWDM grid (G.694.2) from 1270-nm through 1610-nm.

The transceivers are shipping in volume.
