SYSTEMS AND SUBSYSTEMS
Dynamic spectral equalizer
The DGEP dynamic spectral equalizer is a modular subsystem that provides gain flattening and tilt control in optical networks. It utilizes patented all-fiber acousto-optical filter technology to accomplish dynamic optical filtering in the fiber, delivering high performance with low insertion loss. Network equipment providers can implement dynamic, automatic modification of the spectral-gain characteristics of optical amplifiers to compensate for gain shape changes, gain tilt, and accumulated gain ripple. When inserted into the mid-stage of EDFA line amplifiers, DGEP equalizers compensate for spectral impairments in either the C- or L-band.

The OMNIFiber SM adapter transforms any OMNIScanner into a comprehensive laser-based singlemode fiber-optic certification tool. The product measures optical loss and length at 1,310- and 1,550-nm wavelengths. In OMNIFiber SM, the fiber testing is delivered by checking duplex fibers in both directions, at both wavelengths, from a single autotest. Results are automatically compared against fiber-optic standards to certify links instantly and are also stored for subsequent certification reporting. Results are also assessed against fiber-optic applications such as Gigabit Ethernet and Fibre Channel, and the OMNIFiber then delivers a list of applications that a fiber installation can successfully run.

VCSEL alignment features
Two new features are available on the company's Model 410 and Model 860 Omni laser bonders for enhancing precision during pickup and alignment of VCSELs with target sites on submounts. The video image marker creates and stores a fixed video overlay of crosshairs in the form of a bit map for centering the VCSEL's emission point as well as up to 10 different video patterns that can be superimposed on the submount on which the VCSEL is to be bonded. The precision station allows the VCSEL to be taken from a Gel Pak with an unheated tool without damaging the Gel Pak and then to subsequently be handled with a preheated tool in preparation for placement on the submount.
