JDSU Debuts 850nm Testers

SAN JOSE, Calif. and OTTAWA -- JDS Uniphase Corporation (Nasdaq: JDSU and TSX: JDU) today announced a suite of test and measurement instruments for manufacturers of fiberoptic components that operate at 850 nm wavelengths and at data rates of up to 10 Gb/s. The 850 nm wavelength is used for enterprise applications where fiberoptics are being used to move large amounts of data over short distances. With these new modules, JDS Uniphase’s Multiple Application Platform (MAP) now provides a full range of test capabilities for either multimode or single-mode at 850, 1310 and 1550 nm wavelengths.

The enterprise data communications market uses 850 nm wavelength fiberoptics for short reach applications, such as moving information between buildings on a campus, or very short reach, such as between bays in an equipment rack. The MAP is a modular instrument system that makes testing more economical, thereby helping to reduce the cost of manufacturing. With nineteen cassettes, MAP is also very flexible, and allows manufacturers to move more easily into other product areas. Vendors are designing products now for the demand they expect for 10 Gigabit Ethernet (GbE) products. New MAP cassettes for these applications include:

The MAP 850 nm Optical Transmitter Cassette is an electrical to optical converter that provides maximum output powers of >-4.0 dBm for 10 GbE and Fibre Channel and meets the IEEE 802.3ae reference transmitter specifications for extinction ratio, output power, eye mask and intrinsic jitter.

The MAP 850-1550 nm Optical Receiver Cassette includes 850, 1310 and 1550 nm wavelength ranges in a single reference receiver for data rates up to 10 Gb/s. It meets or exceeds the IEEE 802.3ae requirements for sensitivity, overload, and intrinsic jitter.

The MAP Precision Attenuator Cassette with Power Control is both an attenuator and power meter in one cassette and is available in either multimode or single-mode for 850, 1310 and 1550 nm wavelengths. Combining the functions reduces space and cost, and also simplifies calibration. With Power Control, the user can choose a desired optical power and the Precision Attenuator will automatically provide the correct amount of attenuation.

The MAP Variable Backreflector Cassette is designed to inject precision amounts of light back into a transmitter. It meets the functional test requirements for IEEE 802.3ae and is required for testing relative intensity noise and dispersion penalty for 850, 1310, and 1550 nm wavelengths.

The new MAP Polarization Controller Cassette is used when measuring worst case relative intensity noise and dispersion penalty for transmission products as per IEEE 802.3ae for 10 Gb/s applications at 1310 and 1550 nm wavelengths. It is also used to measure polarization dependent loss or polarization mode dispersion for fibers and passive components.

DFB Laser and Tunable Laser Source Cassettes are currently available for the MAP, and JDS Uniphase is introducing two additional sources: the Fabry-Perot Laser Cassette and LED Source Cassette (multimode and single-mode) for cable assembly and passive component testing.

The MAP, first introduced 18 months ago, now has nineteen cassettes, offering a broad range of test capabilities at 850, 1310, and 1550 nm wavelengths at data rates up to 10 Gb/s. The modular design saves space, reduces cost and provides flexibility in testing over a wide range of functions.

Demonstrations at Optical Fiberoptic Communications (OFC) All of the above products, and other JDS Uniphase Instrumentation products, will be shown in working demonstrations at OFC in Atlanta, March 25-27 in the JDS Uniphase booth #2842.
