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.
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.
