in performance to higher bandwidth 100Mbps speed, and the per-port modularity plus stacking
provide for port expansion.
LH8050A has 16 ports per unit,
is stackable up to 3 units, and economically
supports all fiber types to the desktop for
maximum
security and flexibility .

Example 3: Future-proofing, industrial environments: In heavy industrial plants (such as
steel mills, electrical generating stations, telecom central offices, hospitals, etc.), fiber LAN
cables are usually used for noise immunity and electrical ground-isolation. In this kind of
environment where computer systems are used to monitor and / or manage operations, an
Ethernet fiber link is used to collect real-time data via SNMP agents in the equipment. The
SNMP management fiber network almost always operates at 10 Mbps. Network management
workstations and network servers use 100Mbps ports to the high performance nodes.
The LH8050A Dual-Speed Fiber Hub is ideal in these situations. The fiber ports are
economical and may be a mix of 10 and 100Mbps, and may be any quantity or mix of standard
port connector types. Individual 10/100 RJ-45 ports may be configured also, and an optional
SPM can segment local users from the rest of the network. Stacking provides capacity for up to
48 ports, and the LH8050A can be stacked with an LH8016-C for a mix of RJ-45 and fiber
ports. The flexibility results in a “future-proof” fiber hub. The illustration above shows this
type of installation.
