Product Overview
DESCRIPTION
The FX82051 unmanaged Ethernet switch provides five 10BASE-T/100BASE-TX ports and one
100BASE-FX fiber port for the transport of bidirectional Ethernet data. Two fibers are required to
transport bidirectional data over the fiber port. Available in multimode and single-mode versions, the
FX82051 Ethernet switch is designed for point-to-point applications (refer to Figure 1).
Figure 1. FX82051 Point-to-Point Application
Features of the FX82051 Ethernet switch include the following:
• User-selectable networking functions for each 10BASE-T/100BASE-TX port:
– Autonegotiation between 10 Mbps and 100 Mbps data rates and between full-duplex
and half-duplex modes
– 10 Mbps or 100 Mbps selectable
– Full-duplex or half-duplex mode selectable
– Enabling/disabling of flow control
NOTE: The 100BASE-FX fiber port is automatically forced to full-duplex 100 Mbps operation.
• Auto MDI/MDI-X (Medium Dependent Interface/Medium Dependent Interface Crossover)
operation
• Compliant with IEEE 802.3, 802.3u, and 802.3x standards
• Multimode fiber support for distances up to 6 km
• Single-mode fiber support for distances up to 46 km
• Compatible with other Ethernet equipment:
– 10BASE-T/100BASE-TX compatibility with all Pelco
®
and third-party 10BASE-T/
100BASE-TX Ethernet devices
– Fiber optic compatibility with all Pelco Ethernet devices that use two fibers per fiber port
– Fiber optic compatibility with third-party 100BASE-FX Ethernet devices (applicable to
multimode ST and SC versions only)
• Laser diode for transmission of optical signals
NOTE: The FX82051 switch is a Class 1 laser product that complies with FDA radiation
performance standard 21CFR Subchapter J and with IEC 60825-1 Edition 1.2, 2001-08.
