10Basefl Network Cabling; Maximum Cable Length - Automationdirect.com DirectLOGIC DL205 Series User Manual

10BaseFL Network Cabling

The H2-EBC-F and the H2-ERM-F modules have two ST-style bayonet connectors. The ST-
style connector uses a quick release coupling which requires a quarter turn to engage or
disengage. The connectors provide mechanical and optical alignment of fibers.
Each cable segment requires two strands of fiber; one to transmit data and one to receive data.
The ST-style connectors are used to connect the H2-Exx-F module to a PC or a fiber optic
hub or repeater. The modules themselves cannot act as repeaters.
The H2-EBC-F and the H2-ERM-F modules accept 62.5/125 multimode fiber optic (MMF)
cable. The glass core diameter is 62.5 micrometers, and the glass cladding is 125 micrometers.
The fiber optic cable is highly immune to noise and permits communications over much
greater distances than 10/100BaseT.

Maximum Cable Length

The maximum distance per 10/100BaseT cable segment is 100 meters or 328 feet. Repeaters
extend the distance. Each cable segment attached to a repeater can be 100 meters. Two
repeaters connected together extend the total range to 300 meters. The maximum distance
per 10BaseFL cable segment is 2,000 meters or 6,560 feet (1.2 miles). Repeaters extend the
distance. Each cable segment attached to a repeater can be 2,000 meters. Two repeaters
connected together extend the total range to 6,000 meters.
