Optical Fiber Identifier

Among those famous optical fiber identifier manufacturers and suppliers in China, Green Telecom Tech Co.,Ltd can offer you customized ofi, fiber identifier, optical fiber finder made in China. Our factory is waiting for your contact.   Description The GFI Live Fiber Identifier allows you to detect traffic and measure signals anywhere onsinglemode fibers without having to disconnect them . It also lets you check for signal presence before rerouting or maintenance , perform continuity tests and verify cable labeling. Based on non-destructive macrobending technology,the GFI doesn't disrupt traffic,damage or overstress the fiber,enabling efficient,accurate and reliable data acquisition. Features ● Indicate the signal directions in fiber ● Indicate the signal presence or absence(Live ordark fiber) ● Detect tones 270Hz, 1kHz and 2kHz to verify the modulated signal type ● Handhold design ● Build in VFL 1mw or 10mw optional ● Battery low indication ● Powered by 2 units of 1.5V AA batteries ● One-year warranty and Three-year recommended calibration interval Specification
