Overview
The Luna 6435 is a lightwave component analyzer in the Luna 6400 Series for testing passive optical components and fiber optic networks. It measures and analyzes the insertion loss (IL) and return loss (RL) distribution, as well as length, scanning the device under test in either reflection or transmission mode.
The instrument uses optical frequency domain reflectometry (OFDR) to measure backscattered or transmitted light as a function of distance. Compared with the Luna 6415, the Luna 6435 extends the measurement range to 500 m in reflection (1000 m in transmission), making it suited to testing networks, amplifiers and other fiber systems.
By analyzing RL, IL and length or delay with a single instrument in reflection or transmission, the Luna 6435 is intended to reduce the cost and complexity of test while increasing throughput. The instrument can be controlled remotely through SCPI commands over TCP/IP.
The Luna 6400 Series has been discontinued by the manufacturer; Luna lists the Lightwave Component Analyzer LWA 7601-C as its replacement.
