100-Mbps switching
services for large,
high-performance
LANs.
Mixed-media
configurations for
maximum flexibility.

fiber ports, all
connector types and
speeds.
Configurable with
RJ-45 (copper) ports,
10/100 autonegotiation.
Full or half-duplex
operation, autosensing.
W
ith the Modular Fiber Switch,
you can configure any mix
of fiber or RJ-45, 100-Mbps or
10-Mbps switched ports and
connector types. The switch
provides the switching speed and
the reliability to smoothly support
multiple workgroups, each with
its own switched 100 Mbps or
10 Mbps domain, for increased
performance using any available
fiber media type or twisted-pair
cabling.
Choose from a variety of
connectors. The twisted-pair
ports are 10/100 autonegotiating.
Mixed-media combination
modules are also supported by
the switch.
Key Features
In a typical application, groups
of standard dual-speed 10-/
100-Mbps hubs, or 100-Mbps
hubs and switches, will form a
series of subnets for workgroups
or multi-system power users.
Each subnet is served by a
separate switched port on the
Modular Fiber Switch, and each
of these subnets has full 100Mbps or 10-Mbps bandwidth.
Local traffic on one subnet, either
100 Mbps or 10 Mbps, is switchisolated from the other subnets
for high overall network
performance.
For remote offices, campus
environments, ISPs, or telecommunications facilities, select
the 100-Mbps multimode SC fiber
module (LE1421C-40K). It supports
full duplex transmissions up to 40
kilometers (24.8 miles). That’s
twice the distance of the other
100-Mbps fiber modules.
Easy to install and use, the
Modular Fiber Switch is designed
for organizations with multiple
workgroups, remote offices, and
network traffic centers. The
switch automatically learns and
maintains addresses of attached
nodes, so it adapts to network
changes and expansions for plugand-play operation. Frontmounted LEDs provide status
information on each port.

Recognize any of these
situations?
• You wait more than 30
minutes to get through to a
vendor’s tech support.
• The so-called “tech” can’t
help you or gives you the
wrong answer.
• You don’t have a purchase
order number and the tech
refuses to help you.
• It’s 9 p. m. and you need help,
but your vendor’s tech
support line is closed.
According to a survey by Data
Communications magazine, 90%
of network managers surveyed
say that getting the technical
support they need is extremely
important when choosing a
vendor. But even though network
managers pay anywhere from 10
to 20% of their overall purchase
price for a basic service and
support contract, the technical
support and service they receive
falls far short of their
expectations—and certainly isn’t
worth what they paid.
At Black Box, we guarantee
the best value and the best
support. You can even consult our
Technical Support Experts before
you buy if you need help selecting
just the right component for your
application.
Don’t waste time and
money—call Black Box today.
