US Conec develops PRIZM LightTurn connector/NeoPhotonics introduces 10G PON transceivers for FTTP networks
MARCH 28, 2010 — US Conec has announced the immediate availability of its PRIZM LightTurn connector for photonic turn parallel optic interconnect. Designed as a miniature detachable connector for Avago Technologies’ new MicroPOD 120-Gbps board-mounted parallel optic modules (see “Avago Technologies unveils miniature embedded parallel optics modules”), the PRIZM LightTurn connector provides passive alignment and retention features that enable multiple re-matings perpendicular to the printed circuit board.
The 7.4×5.7-mm PRIZM LightTurn connector consists of a multi-fiber ferrule with a photonic turn TIR lens array accepting cleaved fibers and a single outer housing. The termination is simple and low cost, says US Conec; it requires no polishing of fibers and is easy to test, the company adds.
The use of the PRIZM LightTurn connector in combination with US Conec’s MTP brand MPO style connector provides a significant increase in card edge port density compared to using SFP transceivers, conventional array transceivers, or parallel active optical cables on the card edge, the company asserts. The connector is designed for use across multiple applications including telecom, datacom, and the emerging high speed computing markets.
US Conec will sell components to cable assembly makers, as well as provide the necessary training and support worldwide to enable multiple sources to equipment and systems makers.
MARCH 23, 2010 — NeoPhotonics in San Diego is introducing a line of 10G PON transceivers, compliant with the ITU-T G987.2 and IEEE 802.3av networking standards, to go with its GPON and GEPON modules for fiber to the premise (FTTP) networks for optical line terminals (ALT) and optical networking units (ONU) in central offices and at customer premises.
The ITU-T G987.2 compatible transceivers support data rates of 10G in the downstream direction and 2.5G burst mode transmission in the upstream direction covering nominal link budgets of 29 dB and 31 dB.
The IEEE 802.3av compatible transceivers support data rates of 10G in the downstream direction and 1G burst mode transmission in the upstream direction covering link budgets of up to 30.5 dB. The ALT transceivers come in the XFP form factor, and the ONU transceivers come in the SFP+ form factor.
