Ottawa, Canada and San Jose, California - March 12, 2002 - JDS Uniphase Corporation (Nasdaq: JDSU and TSE: JDU) today announced its Gain Equalization Monitor (GEM), a compact, low-cost addition to its family of optical monitors for fiberoptic communication systems providers. The GEM measures optical power and wavelength accurately for DWDM networks that require remote monitoring.

The need to control increasingly complex networks, reduce downtime, lower operating costs and quicken response time to system faults all contribute to the demand for optical monitoring. The use of optical monitors, however, has been limited by their size and cost. At approximately 120 x 82 x 17 mm, the GEM is one of the smallest optical monitors, and its low list price compares very favorably to that of comparable models.

Its RS-232 and DPRAM electrical interface ease integration with systems and its response time of << />150 ms and relative power accuracy of 0.5 dB meet the requirements of most applications. The GEM covers the entire C-band at 100 GHz wavelength spacing. An L-band model at 100 GHz is expected by May and a 50 GHz model is planned for later in the year.

Applications
The GEM is expected to be used primarily, at first, for gain equalization at amplification nodes. Used in conjunction with JDS Uniphase's Dynamic Gain Equalizer, for example, the GEM can be used in systems that provide dynamic and remote controlled gain flattening. Other applications include signal power and wavelength verification and equalization after add/drop nodes, signal verification and troubleshooting during commissioning, and fault localization.

Availability
The Gain Equalization Monitor is available for order from JDS Uniphase representatives and distributors worldwide.
