AFL Telecommunications' Xpress Fiber Management Optical Cassette product line is a family of preterminated fanout modules that streamline the deployment of optical network infrastructure. The primary function of these products is to breakout multi-fiber ribbon connectors to simplex or duplex style connectors for connection to adjacent network elements. These cassettes are available in the industry standard LGX® footprint as well as select Corning Cable Systems™ footprints to support embedded base installations. All modules feature a durable powder coat finish, and are compatible with all 1U-4U LanSystem™ platforms. All modules are clearly labeled with a silk-screened "A" and "B" positioning reference to ensure proper polarity is maintained in the network, referenced to the polarity convention being deployed.
