2×2 Fiber Optical Bypass Box-FOBBF

2×2 Fiber Optical Bypass Box-FOBBF


The 2×2 BiDi Industrial Bypass Optical Network Switch utilizes fiber-to-fiber technology over an angled surface to achieve ultra low losses and crosstalk. It is an external Optical Bypass Box for 10 /1Gbps fiber Gigabit Ethernet networks. The 2×2 BiDi Industrial Bypass Optical Network Switch protects from network failures and is easy to implement network maintenance by ensuring network integrity. It is suitable for all bi-directional protection switching applications where premise-side connectivity is not required in the bypass state. The optical bypass box provides excellent performance on your network and posses the advantages of compact and competitive cost. Lightwave Link 2×2 BiDi Industrial Bypass Optical Network Switch fully complies with RoHS Directive 2011/65/EU.
