TriQuint Optoelectronics Makes Breakthrough with DWDM SFP Transceiver

2/20/2004 - TriQuint Semiconductor's Optoelectronics Division (Nasdaq: TQNT), a leader in optical communications components and modules for metro, access and enterprise markets, announced the addition of DWDM (dense wavelength division multiplexing) SFP transceivers to its NetLight® SFP transceiver family. This new module allows customers to consolidate wavelength management and significantly reduce the complexity and cost of DWDM in metro core and edge applications.

TriQuint’s DWDM SFP transceivers use the company’s cooled laser technology with internal wavelength control management. They address the growing challenges of fiber exhaust and provide an upgrade path to DWDM at significantly reduced upfront costs.

"This is an exciting announcement because it is truly a disruptive technology that enables our customers to rethink their product architectures and strategy," said Glen Riley, Vice President and General Manager for TriQuint Optoelectronics. “It is now possible to consolidate wavelength management directly into the optical ports on the edge switch and significantly reduce the complexity and cost of DWDM in metro core and edge applications. This is possible because of TriQuint’s years of experience and unparalleled expertise in DML laser technology, cooled laser packaging capability, and SFP module design. We have customers that are very interested in incorporating these new DWDM SFP transceivers into their systems as soon as possible.”

The ‘plugability’ of an SFP DWDM transceiver offers several advantages over the complexities of the more costly tunable laser technologies. Wavelength management is as simple as plugging in a transceiver of the needed wavelength. Because TriQuint DWDM SFP transceivers are compatible with the power dissipation requirements of existing SFP sockets, customers may offer an upgrade path for new systems as well as those already installed. This upgrade path significantly lowers the upfront investment required to implement DWDM capability.

Technologies that enable this DWDM advancement include TriQuint’s proprietary cooled optical engines, which feature very low power dissipation and are designed specifically for 2.5Gb/s SFP modules. These engines are powered by TriQuint’s leading edge DML and APD devices. The optical engines used in 2.5Gb/s DWDM SFPs are part of TriQuint’s miniaturized TOSA and ROSA engine family designed to power any multi-sourced agreement (MSA) optical module form factor, at 2.5Gb/s and 10Gb/s, including 300 pin transponders, XFP, SFF, SFP, and GBIC. The transceivers operate from 0°C to +70°C, thereby meeting SFP cage system power dissipation limitations.

Manufactured at its Matamoros, Mexico facility, TriQuint’s new versions of the NetLight® SFP transceivers target DWDM interfaces up to 2.5 Gb/s with 100GHz spacing and high wavelength stability. With a high performance APD receiver and a typical launch power of 2 – 3 dBm, total transceiver power dissipation is typically under 1W. The DWDM SFP transceivers are offered with digital diagnostic monitoring per the SFF-8472 standard and are available with TriQuint's robust, color-coded bail latch that prevents in-service removal and operates in all faceplate designs.

TriQuint’s cooled DWDM SFP is the latest addition to a complete portfolio of SFP transceivers, in both TDM and CWDM versions, for Sonet/SDH, Gigabit Ethernet and Fibre Channel applications. The NetLight portfolio of SFP transceivers includes OC-48 LR-2 (STM-16 L-16.2) and a CWDM offering that is wavelength compliant as defined in ITU-T Recommendation G.694.2.
