SUGAR LAND, Texas, Nov. 7 -- Applied Optoelectronics Inc. (AOI), a manufacturer of laser diodes, photodetectors and optical modules for fiber optic communications systems, is introducing optical modules for passive optical networks (PONs).

AOI is offering bidirectional and tri-port optical blocks for Gigabit PON (G-PON) and Ethernet PON (E-PON) applications. These optical blocks incorporate the company's advanced laser diodes and photodiodes with integrated wavelength division multiplexers (WDMs) to enable full-duplex communications over a single optical fiber.

Both types of modules are offered in a variety of configurations depending on the optical link budget required. They are offered with both Fabry-Perot- and distributed feedback- type laser diodes. Several options for photodetectors are also available. The G-PON style optical blocks support downstream bit rates up to 2.488 Gb/s and upstream rates of 1.25 Gb/s. Both optical line terminal- (OLT) and optical network unit- style devices are available.

"These optical blocks offer the performance necessary for next-generation PON-type fiber-to-the-home networks for both G-PON (ITU-T G.984) and GE-PON (IEEE 802.3ah) applications," said Stefan Murry, AOI's vice president of sales and marketing.

Both OLT- and optical network terminal- style devices feature single-fiber output and the wavelength-separation components necessary to allow full-duplex communication over a single fiber using WDM. Samples of these devices are available in a variety of configurations. Volume shipments are expected to begin in December.

GLOSSARY
optical
Pertaining to optics and the phenomena of light.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
