Opnext's 40Gbps DQPSK module moves into full production

Opnext Inc of Fremont, CA, USA has announced that its 40Gbps differential quadrature phase-shift keying (DQPSK) module has moved to full production and is now shipping in volume.

According to the firm, the demand for 40G interfaces continues to grow due to increases in IP and video networks driving the upgrades of regional, long-haul and submarine networks. In a recent report, Ovum forecasted that the 40G DWDM market for DQPSK modules would grow at a compound annual growth rate (CAGR) of 16% from US$175m in 2010 to more than US$360m in 2015, says Opnext.

"A large percentage of carrier fiber plants require increased dispersion tolerance that is provided by our DQPSK module in conjunction with tunable dispersion compensation (TDC)," said Tadayuki Kanno, president of Opnext's modules business unit. "For this reason, the Opnext 40G DQPSK MSA module is being widely adopted and implemented by our system vendor customers in addition to our successful Opnext DPSK module."
