Introduction
Micronet SP342B / SP343B Wavelength Division Multiplexing (WDM) Media
Converter provides multi-wavelengths of light, transmitting multiple streams
of information along a single fiber up to 20 kilometers with minimal interference.
It’s suitable for any data communication application where single-mode fiber is
in short supply or expensive to provision.

Installation
This device is plug-and-play. Please follow the steps to install the media
converter.
1. SP342B (T1550/R1310) and SP343B (T1310/R1550) must be installed in
pair.
2. Connect the supplied AC to DC power adapter to the receptacle at the back
of the converter.
3. Attach the plug into a standard AC outlet.
4. Connect TX port and FX port with right cable to make link.
For cable selection, refer to the following table:
Speed Cable Type Max. Length
10Base-T
100Base-TX
Cat. 3, 4, 5 UTP/STP 100 m
100Base-FX Single-mode, simplex
fiber, 9 or 10/125µm
20 km
WDM Media Converter provides one TP port and one simplex-fiber port,

simply repeating the signals from 10/100Base-TX to suitable format for
transmission over fiber cables. It supports auto negotiation on TP port to sense
the speed and the duplex mode.
The media converter supports auto uplink (auto MDI/MDI-X) on TP port and
LFPT (Link-Fault-Pass-Through). Users can just connect the TP side with
either straight-through or cross-over cable. With LFPT enabled, it will inform
the other end by turning OFF the remote end's link LEDs when cable in one
end is OUT. It is enabled by default.
