4-Port Ethernet to Coax
Industrial Media Converter
OVERVIEW
These IFS 4-Port Ethernet to Coax/TP Industrial Media Converters
are high-performance modules that combine two well-proven
technologies—Ethernet and VDSL2— providing a cost-effective
solution for utilizing an existing telephone cable* or coax cable
infrastructure when migrating from analog to an Ethernet/IP system.
The MC251-4P/1CXT model provides full IEEE802.3-af (15.4w) on
each individual 4 RJ45 ports and serves as a PSE device.
These modules provide plug-and-play installation and can be used
in combination for either telephone cable or coax cable installations.
These modules can also be used with the MCR200-1T/CX over coax
only for rack mount installations at the head-end.
The one box design allows for easy set-up as either a client-side
(CPE) or central-side (CO) operating device. The module is IEEE
802.3 compliant and supports multiple network protocols. In
addition, the module provides on-board feature-rich diagnostic LEDs.
These IFS 4-Port Ethernet/PoE-af to Coax/TP Industrial Media
Converters can extend Ethernet transmission up to .87 miles (1.4km)
on standard telephone (POTS) type cable or 1.49 miles (2.4km) on
coaxial cable. Performance is based on bandwidth requirements and
quality of the cable used.
* The MC251-4P/1CXT and MC250-4T/1CXT can utilize standard telephone (POTS)
type cable for transmission of Ethernet/IP data. It is not designed for transmitting
Ethernet data on a PBX system or public switch telephone network (PSTN).
