November 2, 2005 Sugar Land, TX -- Applied Optoelectronics, Inc. (AOI), a manufacturer of laser diodes, photodetectors, and optical modules for fiber-optic communications systems, has introduced a line of optical modules for use in passive optical networks (PONs). The company is offering bi-directional and tri-port optical blocks for GPON and EPON applications.

The optical blocks incorporate proprietary advanced laser diodes and photodiodes along with an integrated wavelength division multiplexers (WDMs) to enable full-duplex communications over a single optical fiber. Both types of modules come in a variety of configurations, depending on the optical link budget required.

The modules are being offered with both Fabry-Perot (FP) and Distributed Feedback (DFB)-type laser diodes. Several options for photodetectors are also available. The GPON style optical blocks support downstream bit rates up to 2.488 Gbit/sec and upstream rates of 1.25 Gbit/sec.

"These optical blocks offer the performance necessary for next-generation PON-type fiber to the home networks for both GPON (ITU-T G.984) and GEPON (IEEE 802.3ah) applications," comments Dr. Stefan Murry, AOI's vice president of sales and marketing. "AOI has been a key subcomponent supplier to the BPON market for years, and we are proud to offer these more integrated devices that will enable our customers to realize faster time to market, as FTTH applications continue to proliferate."

Both OLT- and ONU-style devices are available. Both types of devices feature single-fiber output and the wavelength-separation components necessary to allow full-duplex communication over a single fiber using WDM, according to the company.

Samples of the devices are available, with volume shipments set for December 2005.
