China Telecom (CHA), the largest Chinese fixed-line operator, has successfully tested Alcatel-Lucent’s (ALU) multi-carrier EV-DO (a 3G technology) wireless network based on the Revision B (Rev B) standard. The Chinese operator’s subsidiary Shanghai Telecom has reportedly installed the multi-carrier EV-DO solution, which significantly enhances network throughput and reduces data latency (using multiple carriers) to meet increasing customer demand for high-bandwidth applications.   The multi-carrier EV-DO Rev B network, which represents an upgrade from EV-DO Rev A, has demonstrated highly encouraging throughput levels in the lab test with peak download speeds reaching up to 9.3 megabits per second (Mbps). This will effectively enhance customer experience who subscribe to high-bandwidth wireless services including Voice-over-Internet Protocol (VoIP), high definition video streaming and other multimedia applications.    Leveraging Alcatel-Lucent’s network infrastructure support, Shanghai Telecom became the first Chinese carrier to commercially launch a CDMA EV-DO network in China in March ...

Opnext Inc. (OPXT), a designer and manufacturer of optical modules and components that transmit and receive data, is expected to report its first quarter results on August 6.

Management expects market softness to affect the June quarter. 10G sales are expected to decline. Sales from 40G products are anticipated to return to normal levels after a decline in demand in the March quarter. In view of the above mentioned factors, Opnext expects revenues between $80 million and $90 million in the first quarter of fiscal 2010 while the consensus estimate is $84 million. In the previous quarter, the company reported sales of $84 million.

Telecommunications partnerships -- such as Nokia Siemens Network (NSN) and Alcatel-Lucent (ALU) -- and data communications networks such as Cisco (CSCO) are becoming increasingly congested as the result of growing demand from consumers, enterprises and institutions for high-bandwidth applications. This bandwidth constraint has caused network
