JANUARY 8, 2008 By Stephen Hardy -- Mintera Corp. (search for Mintera) has successfully transitioned from a producer of 40-Gbit/sec (40G) line cards to modules with the announcement of its first transceiver shipment. The MI 4000XM 300-pin DWDM module, developed in collaboration with JDSU (search for JDSU), leverages Adaptive-DPSK, Mintera's version of differential phase-shift keying (DPSK).
The December 2007 shipment was made to a new European customer, one of what Mintera called "several" new customers who have opted for the device. Company President and CEO Terry Unter predicts the MI 4000XM "will be shipping in significant volumes early this year."
"The DWDM 40-Gbit/sec module market takeoff was obvious in 2007," said Michael Howard, principal analyst at Infonetics, in a Mintera press release. "Mintera's release of the MI 4000XM Adaptive-DPSK product is a timely response to the changing market needs, which enables the 40-Gbit/sec DWDM interface to be delivered in a common physical form factor. This reduces the number of variants, driving up volume, leading to lower costs. The move to common, modular solutions was instrumental in enabling the 10-Gbit/sec market to take off, and we believe it will have the same effect for 40 Gbits/sec."
Mintera's Adaptive-DPSK is an outgrowth of a proprietary version of DPSK called partial DPSK. (See our story that describes partial DPSK.) Adaptive-DPSK supports long transmission distances and 50-GHz line widths. First-generation 40G modulation formats, such as optical duobinary and carrier-suppressed RZ, had trouble with line widths smaller than 100 GHz.
JDSU and Mintera announced last October that they would partner to leverage Adaptive-DPSK in module format. (See story here.) The MI 4000XM is compliant to ITU-T G.693 for optical interfaces and OIF SFI-5 standards, Mintera says. It also incorporates an electrical multiplexer/demultiplexer for compatibility with 40-Gbit/sec framers, as well as a 300-pin MSA connector with support for I2C commands.
