Optium starts producing 40G DPSK and SFF NRZ transceivers

JANUARY 16, 2008 -- The DPSK and SFF NRZ products complement the company's existing 40G portfolio of tunable NRZ and optical duobinary 300-pin transceivers.

JANUARY 16, 2008 -- Optium Corp. (search for Optium), a supplier of high-performance optical subsystems, has announced the transition of two additional 40-Gbit/sec offerings to production during the company's second fiscal quarter, ending Feb. 2. Optium's new 40G differential phase-shift keying (DPSK) 300-pin transceiver and 40G small-form-factor (SFF; search for SFF) non-return-to-zero (NRZ) 300-pin transceiver each began shipping to customers in early December 2007 as part of Optium's fiscal 2008 ramp of its 40G product line. Optium's full line of 40G transceiver products will be on display at the Fiber Optics Expo (FOE) 2008 in Tokyo, Japan, Jan. 16-18.

The DPSK and SFF NRZ products complement the company's existing 40G portfolio of tunable NRZ and optical duobinary 300-pin transceivers. Optium says all of its 40G products are offered with a 300-pin multiservice agreement (MSA) interface and address both line- and client-side applications. Optium's 40G modules are designed to support the OIF SFI-5 standard and applicable Telecordia/ITU interface requirements.

The company also intends to further expand its 40G product line with a return-to-zero differential quadrature phase-shift keying (RZ-DQPSK; search for RZ-DQPSK) offering currently targeted for release by the end of fiscal 2008. Optium expects the RZ-DQPSK device to offer higher tolerance to chromatic and polarization-mode dispersion, along with a narrow spectrum to be "easily transported" on reconfigurable optical add/drop multiplexer (ROADM)-based networks with a 50-GHz channel plan and optmizied for metro and long-haul networks.

"Demand for 40-Gbit/sec transceivers continues to build as our customers adopt 40-Gbit/sec solutions to address increasing bandwidth requirements cost effectively," comments Tony Musto, vice president of sales and marketing. "Similar to our approach in 10 Gbits/sec, we are developing a powerful portfolio of 40-Gbit/sec products by utilizing a common 40-Gbit/sec 300pin platform with diverse modulation schemes and advanced features, including tunability on multiple modulation formats, high tolerance to chromatic dispersion and polarization mode dispersion (PMD) impairments, and the ability to work in a network through multiple ROADMs at 100-GHz and 50-GHz channel spacing."
