October 25, 2005 Santa Ana, CA -- OE Solutions has introduced a family of Small Form Factor (SFF) optical line terminal (OLT) transceivers for use in Gigabit Ethernet passive optical networks (GEPONs). The company says its OBL4333F product family addresses the IEEE 802.3ah Ethernet in the First Mile (EFM) standard, supporting 1000BasePX10-D for 10-km applications, 1000BasePX20-D for 20-km applications, and a non-standard, extended link budget 1000BasePX20-D+ for applications beyond 20 km.
The company says its PX20 transceivers feature best-in-class performance with a burst mode sensitivity better than -30 dBm, output power better than +3.5 dBm, and a loud/soft ratio of 22 dB. According to the company, the transceivers operate over an ambient temperature range of 0 to 70 degrees Celsius and can recover a burst signal with a guard time of less than 100 ns and a settling time of less than 200 ns.
Additionally, the modules incorporate a high speed signal detect (SD) function that has a typical assert/de-assert time of 50 ns for detecting a compliant signal on a subscriber by subscriber basis. The transceiver family conforms to the SFF footprint with a singlemode fiber pigtail, and is offered in a 2 x 6 pin out.
"In a market where cost is so important, we strive to maintain technology and product performance leadership while still being cost-competitive," says Moon Soo Park, OE Solutions' CTO. "This high-performance OLT transceiver family will allow GEPON system providers to design with extra margin, and add features that will provide them the competitive edge that they need."
