Cables and cabling
The DS2500 uses 50 micron (μm) diameter, multimode fibre cables.
The input port connects to an HBA or the previous enclosure in the loop, and the output port connects to
the next enclosure or an HBA on the loop.
Transceivers
The DS2500 uses a short-wavelength fiber optic transceiver called a Small Form-factor pluggable (SFP)
that does not pose a threat to the human eye. SFPs are installed in the I/O module ports.
