Fiber optic requirements
Alcatel-Lucent offers fiber optic cables in lengths between 5 m and 300 m (16.4 ft to
984.25 ft) with an outside diameter of 7 mm (0.28 in). These cables are outdoor/indoor
rated and are available as single mode dual fiber (SMDF) or multi mode dual fiber
(MMDF) cables. The fiber optic cables have LC connectors on both ends. The LC
connectors are waterproofed by the SFP connector (R2CT weatherized connector) that is
installed at the CPRI-cable to Alcatel-Lucent B25 RRH4x30 connection point. Cables are
connected to the B25 RRH4x30 through SFP transceivers.
