Operating safety
TM-76.1 and MD-76.1 devices have been designed and tested for the operating safety in
accordance with Class I of PN-EN 60950 standard.
The device has no built-in disconnecting system. Such a system should be installed
outside the device.
When the device is supplied from a DC source, an easily accessible disconnecting
system should be mounted into the fixed cabling outside the device.
Radiation transmitted by the laser transmitter is harmful to eyes!
URZ DZENIE LASEROWEĄ
KLASY 1
CLASS 1 LASER PRODUCT
Never look at the uncovered socket without a plugged-in fiber optic connector.
The Manufacturer is not responsible for the use of the device in a manner non-compliant
with the operating manual.
This Operating Manual is an integral part of the device delivered to the Users.

1 OVERALL CHARACTERISTICS
1.1 Application
TM/MD-76 linear circuit device enables full duplex digital signal transmission at the bit rate
of 2.048 Mbit/s in accordance with ITU-T/G.703 via a fiber optic line.
TM/MD-76 devices can operate with PCM-30 terminal equipment, telephone switches or
other optional signal sources at the bit rate of 2.048 Mbit/s equipped with the same interface.
The devices are completely transparent for the content of the transmitted signal; it can be
a non-framed or framed signal - provided it complies with the requirements of the G.703
recommendation.
All TM-76, MD-76, TM-77, MD-77 and TM-44 devices can operate with each other if
connected via a fiber optic line. If TM-76 or MD-76 is connected to TM/MD-77, TM-44 four-
channel device, transmission with the first E1 channel is possible.
The optical signal can be transmitted via a couple of single-mode or gradient optical fibers
depending on the version of the device.
Transmission via SM fiber can be realized with devices equipped with LASER type
transmitter.
Transmission via MM fiber can be realized only with devices equipped with both LED
and LASER type transmitters.

Note: 1. Each time a symbol containing the letter "X" instead of its corresponding
digit is used in the Manual, it means that the feature specified in this part
of the symbol is insignificant concerning the discussed parameter and may
be equal to any value from the above-mentioned range. However,
the device symbol indicated in a sales order must contain only digits
following the manufacturer symbol "TM" or "MD" (all features of
the ordered device must be specified).
