Ethernet-over-Copper Extender With Pass-Through PoE

CLFE(X)EO(C,U)

HARDENED

The ComNet™ CopperLine® Ethernet over copper line supports up to sixteen
channels of 10/100Mbps Ethernet with Pass-through PoE over twisted pair
cable (CAT-5, UTP), or over coaxial cable. The single channel units may be
powered by a PoE switch or the included power supply. Four, eight, and
sixteen channel units operate from local power. These units provide the
ultimate flexibility for extending a powered device (PD) over long distance
copper. DIP switches are provided for user-selection of local or remote, 10 or
100Mbps, and 1 pair or 4 pair (UTP) settings.

EXTENDER PASS-THRU

FEATURES

› Transmits individual Ethernet data channels with Pass-

through PoE over standard UTP or Coaxial cable

› Extends Ethernet up to 3,000 feet (914 m) at 10 Mbps or

2,000 feet (610 m) at 100 Mbps over UTP cable

› Extends Ethernet up to 5,000 feet (1,524 m) at 10 Mbps or

2,000 feet (610m) at 100 Mbps over Coaxial cable

› Extended temperature operation from -40°C to +75°C

› Extended Pass-through PoE meets the IEEE 802.3af

standard for Power over Ethernet

› Full 10/100 Mbps Bandwidth

› Supports Multicast, Unicast and Jumbo Frame

› Symmetric Bandwidth provides consistent upload and

download with virtually zero packet loss over the total
usable distance

› Type tested to RFC-2544 TCP/IP network bandwidth packet

transmission standards

› User-selectable data rate for maximum bandwidth and

transmission distance utilization

› Complies with all major IEEE standards and RFC network

protocols for UDP, TCP/IP, HTTP/HTTPs

› Tested and certified by an independent laboratory for full

compliance with the environmental requirements (ambient
operating temperature, mechanical shock, vibration, humidity
with condensation, high-line/low-line voltage conditions
and transient voltage protection) of NEMA TS-1/TS-2 and
CALTRANS Traffic Signal Control Equipment Specifications.

› Designed and manufactured in the USA

› LED status indicators confirm operating status

› Available in small-size, ComFit interchangeable stand

alone or 1RU high rack mounted models

› Lifetime warranty

APPLICATIONS

› Retrofit existing analog CCTV installations to Ethernet-

based systems

› CCTV systems for casinos, airports, school campuses

[1] Distance figures are based on a 50 V PSE PoE power source, and ex ternal power supplies for

the extenders. Distance figures are obtained using in-house testing mirroring installations.
Factor s such as coaxial and copper cable quality, the number of connec tors and splices in the
cable run, the use of PoE, and environmental conditions encountered within the installation
might affect the actual transmission distance and should be taken into consideration. Due
to advanced negotiation signaling required in IEEE802.3at applications, pass-through
applications are limited to IEEE802.3af PD devices only. When using UTP models Pass­Through PoE is only possible in 4-pair mode.
