JANUARY 9, 2008 -- Applied Optoelectronics Inc. (search for AOI), manufacturer of laser diodes, photodetectors, and optical modules for fiber-optic communications systems, has introduced a new family of small-form-factor pluggable (SFP) optical transceivers with industrial operating temperature range.
The transceivers operate up to 4.5 Gbits/sec and are designed to meet the wavelength specifications required in coarse wavelength division multiplexed (search for 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, say AOI representatives, who note that a combination of unique uncooled laser chip design and an optimized module design has enabled AOI's 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," contends 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."
According to the company, the newly released modules offer:
” Hot-pluggable SFP Multi-Source Agreement compliance;
” Serial ID functionality support;
” FC-PI 13.0 compliance;
” Digital diagnostic SFF-8472 compliance; and
” Compliance to 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 currently shipping in volume.
