Optical Connectivity 1 Features • 12- and 24-port configurations • Single-slot LGX packages • Compatible with LANSystem and WME hardware • Available in black with rear MPO connection(s) Xpress Fiber Management ® (XFM) MPO Optical Cassettes AFL’s 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 break out multi-fiber ribbon connectors to simplex or duplex style connectors for connection to adjacent network elements. The Xpress Fiber Management Optical Cassette solution features low-loss MPO style trunk cable assemblies. These cassettes are available in the industry standard LGX ® footprint as well as a selection of 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. Method "F" is also available.
