During its fiscal second-quarter 2008 (ending 2 February), optical subsystem maker Optium Corp of Horsham, PA, USA has transitioned two additional 40Gb/s solutions to production. The new 40Gb/s DPSK 300-pin transceiver and 40Gb/s small-form-factor (SFF) NRZ 300-pin transceiver began shipping to customers in early December as part of Optium’s fiscal 2008 ramp of its 40Gb/s product line.

The DPSK transceiver allows full C-band operation at data rates of 39.8-44.6Gb/s with improved performance in long-haul applications.

The SFF NRZ transceiver is a client-side solution supporting data rates of 39.8-43.1Gb/s that is lower cost than Optium’s tunable NRZ transceiver, and is designed in a smaller footprint (4” x 5” x 0.53”), enabling higher port density on smaller-size line cards (as required by certain customers).

The DPSK and small-form-factor NRZ 40Gb/s products complement Optium’s existing 40Gb/s portfolio of:

• Tunable NRZ transceivers (with full C-band operation at data rates of 39.8-44.6Gb/s) for applications including client-side interface and test equipment; and
• Optical Duo-Binary 300-pin transceivers (which have a modulation format more tolerant to the effects of chromatic dispersion than NRZ) for line-side applications (with full C-band operation at data rates of 39.8-44.6Gb/s).

Optium says that all of its 40Gb/s products are offered with a 300-pin MSA interface (with a footprint of 5” x 7” x 0.7”, unless otherwise noted), are designed to support the OIF SFI-5 standard and applicable Telecordia/ITU interface requirements, and address both line- and client-side applications. The full line of 40Gb/s transceiver products is on display at the 8 th Fiber Optics Exposition in Tokyo, Japan this week (16-18 January).

“Demand for 40Gb/s transceivers continues to build as our customers adopt 40Gb/s solutions to address increasing bandwidth requirements cost effectively,” says Tony Musto, VP of sales & marketing. “Similar to our approach in 10Gb/s, we are developing a powerful portfolio of 40Gb/s products by utilizing a common 40Gb/s 300-pin 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 [ reconfigurable optical add/drop multiplexers ] at 100GHz and 50GHz channel spacing,” he adds. “This module-based approach can enable unmatched design, cost and performance flexibility for our customers as they migrate to next-generation 40Gb/s technologies,” Musto claims.

Optium intends to further expand its 40Gb/s portfolio by the end of fiscal 2008 by launching an RZ-DQPSK solution, which will offer higher tolerance to chromatic dispersion and PMD, along with a narrow spectrum to be easily transported on ROADM-based networks with a 50GHz channel plan and optimized for metro and long-haul networks.
