The TELCOLINE GFP-8B wall-mounted fiber optic coupling has two bus cables and 12 outlets for subscriber cables. It has been designed for wall mounting. Its design allows easy assembly of splitters and adapters (SC / LC) and good access to welding. The sealed housing is made of a PC + ABS composite material resistant to water, dust, moisture and chemical pollution. The configuration of mounting elements and the method of closing the housing allows easy access in the event of the need for maintenance or installation of new system components. The twisted bus cable entries allow the installation of a distribution cable without cutting all the fibers. The muff can be used both inside and outside the facility.
