Maxcom MX3257HD Montageanleitung
MAXCOM PRODUCT SPECIFICATIONS
Description
The rack-mountable MX3257HD fiber optic video
multiplexer is ideal for transmitting 1 channel of video, 2
channels of audio and 1 high speed serial data channel
on one fiber optic cable.
The high speed serial data channel may be either DVB-
ASI or SMPTE-310M. The MX3257HD’s High Speed
Serial data channel employs automatic cable
equalization for error free operation over long coaxial
cable runs.
The MX3257HD operates by digitizing and multiplexing
video, audio and high speed data onto a high-speed
serial data stream, which is then transmitted via fiber
optics.
Because the system employs digital transmission
techniques, performance characteristics are consistent
and maintained over the specified distance with no
degradation of signal.
The MX3257HD is designed to work with standard
singlemode or multimode fiber optic cable and can be
wall mounted or rack mounted. Both transmitter and
receiver come equipped with internal power supplies.
Optical Link LEDs facilitate the continuous monitoring of
the fiber optic system.

1 SAFETY INSTRUCTIONS
THE 3257 SYSTEM MAY CONTAIN A CLASS IIIb LASER. PLEASE OBSERVE THE
FOLLOWING SAFETY PRECAUTIONS THAT APPLY TO LASER EQUIPPED UNITS.
WARNING: Do not disconnect the fiber optic external connector with the power turned
on. Exposure to Class IIIb Laser radiation is possible when the external fiber connector
is disconnected while the unit is still powered up. Ensure the rubber boot is in place
whenever the fiber optic cable is disconnected.
CAUTION: Attempting to make adjustments or performing operations other than those
specified may result in hazardous radiation exposure. Exposure for only seconds can
cause permanent eye damage as well as other injuries.

2 INTRODUCTION
2.1 System Description
The 3257 HD Series is a Video / Audio / DVB-ASI fiber optic multiplexer. The 3257 Series
video modules can be configured to transmit simplex (one direction) or duplex (two direction) video &
audio, and 1 to 4 DVB-ASI signals using CWDM technology. Depending on the distance requirements
between sites, the 3257s may be equipped to operate over multimode or single mode fiber. Distances
between the transmitter and receiver can be up to 3 Km for multimode operation and up to 120 Km for
single mode operation
.
SYSTEM I/O CONFIGURATION
Each of the four ports can be configured for one of the following options:
Simplex Video and Simplex Audio –2 Channels
Simplex Video and Simplex Audio –4 Channels
Simplex Video and Simplex Audio –6 Channels
Simplex Video and Simplex Audio –8 Channels
DVB-ASI –1 to 4 channels
VIDEO / AUDIO TECHNOLOGY:
The 3257 system uses uncompressed 10 bit analog to digital modulation techniques which
provides excellent video quality. The audio circuitry also digitizes the audio signals prior
to transmission. The 2 channels of audio may be used for stereo audio or for two separate
channels of audio.
DVB-ASI Transmission Technology
The ASI option on the 3257HD series will accept any PCM 1Vp-p, 75 ohm
signal up to 600Mbps. The digital electrical signal connected to the BNC connector is
converted to an optical signal. The ASI circuit’s receiver takes the incoming optical signal and
converts it back to electrical I/O: 75 Ohm up to 1Vp-p. The interface will NOT accept bipolar
signals; such as T1, T3, E1 or E3.

3 INSTALLATION
3.1 General Installation
The units may be shelf mounted, 19” EIA rack mounted or table mounted. In
order to mount the units in an 19” rack, the Rack Mount Brackets must be first
installed by mounting the brackets to the mounting holes in the sides of the
3257.
Make sure that there is enough space to pull and connect both the electrical
data and optical cables without stressing them beyond the manufacturer’s
limitation strain specifications or exceeding the cable’s minimum bend radius.
3.2 Power Connection
The 3257 Series is compatible with 90 - 240 VAC power, 47Hz – 63Hz.
The Power Entry Module incorporates an IEC 3 prong power input connector, a switch
and a fuse holder, shown below:
