Introductions: JHA-FG101 series is a 100M/1000M SFP converter/repeater. The converter/repeater has 2 SFP interfaces, which can be used to convert two different wavelengths, different distances, and different modes (single/multimode, dual Various optical fiber digital signals between SFP modules of stranded wire/optical fiber), including Ethernet, ATM, SDH, monitoring signals, etc. For example: wavelength conversion between 1310/1550nm, 1490/1550nm, etc. Adopt high-efficiency conversion circuit, high-quality IC chip, stable performance and excellent quality. It is suitable for various optical fiber digital transmission environments.
