1. Introduction
The industrial rated KCD-303P series supports three switched connections including copper and fiber
for networks over POF (Plastic Optical Fiber). The copper ports support 10/100Mbps auto-negotiation
and auto-MDI/MDIX for Cat.5 plug-and-play. The fiber ports support plug-less connections of high
bandwidth 100Mbps data rate over POF cables. POF technology offers a complementary solution to
UTP copper wire for industrial, office and home networks because it is low cost, weight little, thin,
easy and safe to install and electronic noise immunity.
Depending on the types of the network ports and the supported POF cables, several different models
are defined as follows:
Model Copper Port (RJ-45) Fiber Port (POF) POF Support
KCD-303P-A1 2 ports 1 port 1.5mm
KCD-303P-A2 2 ports 1 port 2.2mm
KCD-303P-B1 1 port 2 ports 1.5mm
KCD-303P-B2 1 port 2 ports 2.2mm
The switch also provide the following advantages:
Plug and Play
No configuration is required in using the switches. With the featured auto-negotiation function, the
switches can detect and configure the connection speed and duplex automatically for the copper ports.
The switches also provide auto MDI/MDI-X function, which can detect the connected cable and switch
the transmission wire pair and receiving pair automatically. This auto-crossover function can simplify
the type of network cables used.
POF Connectivity
The switches support plug-less POF connection. Both model series offer an ideal solution for POF
deployment in home and industrial networks. For the application need, 1.5mm POF and 2.2mm POF
are supported in different models.
Industrial Features
For industrial environment, the main devices are designed with the following enhanced features
exceeding that of commercial Ethernet switches:
High and wide operating temperature
5/18
