Optical Modules for High-Speed Data Transmission
External appearance of optical
tranceiving module TODX2402
Optical modules for high-speed data transmission support two types of optical connectors, small multi-
media interface (SMI) and premises network (PN).
The SMI optical connector is designed for use in digital home appliances and enables bi-directional
(duplex) optical communication with its size as small as the simplex optical connector used for home
digital audio equipment.
The PN optical connector is the modification of JIS F07 optical connector which has achieved success
in industry application.

The TODX2402 optical tranceiving module is an optical transceiver
used with the SMI connector which is designed for use in digital home
appliances.
Since it can communicate at a data rate of 250 Mb/s, it is possible to
transmit Fast Ethernet signals (125 Mb/s) as well as IEEE1394 S100
signals (125 Mb/s) and S200 signals (250 Mb/s).

The TODX2801 optical tranceiving module is housed in a ceramic
package which can be used with plastic optical fiber (APF) and plastic
clad silica optical fiber (PCF).
It can be used to transmit Fast Ethernet signals (125 Mb/s) as well as
IEEE1394 S100 signal (125 Mb/s) over longer distance with the PN
optical connector or the JIS F07 optical connector.
