CLEVELAND -- Keithley Instruments, Inc. (NYSE:KEI) today introduced the latest addition to its family of LIV products, the Model 2502 Fiber Alignment Photodiode Meter. The Model 2502 combines the steps of laser diode fiber alignment and light-current-voltage (LIV) characterization, both of which are crucial to the manufacturing of laser diode modules (LDMs). During manufacture, a short length of optical fiber is aligned and permanently attached to the front facet of the laser diode to provide a convenient optical connection to fiberoptic networks. When fiber alignment is coupled with LIV measurements, manufacturers can perform both operations on the same test stand, eliminating a production bottleneck and greatly improving the throughput of this manufacturing phase. The Model 2502 Fiber Alignment Photodiode Meter provides large and small LDM manufacturers, researchers, OEMs, and system integrators with the sensitive source-measure capability needed for precise excitation, high speed LIV measurements, and repeatable performance. The instrument combines these capabilities with analog feedback required by the fiber alignment process. This analog output can drive fiber micro-positioning systems at speeds 2x to 10x faster than other solutions through the use of early beam skirt detection, wide dynamic operating range, and programming flexibility.
