3.7.1.2 SMF and Trunks
Use the following rules for installing SMF cables:
• SMF cable lengths cannot exceed 15 km (9.32 mi).
• SMF cables must be terminated and/or spliced by a certified fiber-optic cable installer, not by installation engineers.
• SMF is used for new unit installations because the new network switches used have Gbit speeds. SMF has greater
distance capability than multi-mode fiber (MMF) in Gbit applications.
Note Refer to the section
Mesh Architecture
The small form-factor pluggable (SFP) or Mini-GBIC is a compact, hot-pluggable transceiver used in network switch
applications. It interfaces the network switch to a fiber optic or copper networking cable. It is a popular industry format
supported by many network component vendors.
The switches used in the current Mark VIe
control system networking design use SFPs
with LC Connectors to connect to single mode
fiber-optic cable for new installations.
