Overview
Product Data Sheet
MC251-4P/1S
4-Port Ethernet to SFP Industrial Media Converter
IFS Ethernet to SFP Industrial Media Converters
offer four 10/100Mbps Ethernet ports and
100Base-FX transmission on either multi-mode or
single mode optical utilizing SFP technology.
Specifically designed for stable and reliable
operation in electrically harsh and climatically
demanding environments, the module’s slim,
IP-30 standard metal case accommodates
DIN-rail or wall mounting for efficient installation in
multiple applications.
These converters are engineered with a
high-performance switch architecture capable of
providing a non-blocking switch fabric and
wire-speed throughput as high as 1Gbps or
1.2Gbps. With the 2K MAC address table, these
media converters offer wire-speed packet transfer
performance without the risk of packet loss. The
Flow Control function allows these modules to
deliver fast and reliable data transfer. The
MC251-4P/1S model provides full IEEE802.3-af
(15.4w) on each individual 4 ports, while the
MC250-4T/2S model is a non-PoE unit designed
for drop-and-repeat applications.
Providing extended distance Ethernet
transmission, these units are well suited for
remotely deployed edge devices such as IP
cameras, access control, VoIP and wireless
access points.
