SUGAR LAND, Texas -- Applied Optoelectronics, Inc., a leading manufacturer of laser diodes, photodetectors, and optical modules for fiber optic communications systems, today is introducing optical modules for Passive Optical Networks (PONs).
AOI is offering bi-directional 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 along with an 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 (FP) and Distributed Feedback (DFB) type laser diodes. Several options for photodetectors are also available.
The G-PON style optical blocks support downstream bit rates up to 2.488 Gbps and upstream rates of 1.25 Gbps. Both OLT and ONU 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,” comments Dr. Stefan Murry, AOI’s Vice President of Sales and Marketing. “AOI has been a key subcomponent supplier to the B-PON 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 ONT style devices feature single-fiber output and the wavelength-separation components necessary to allow full-duplex communication over a single fiber using WDM.
