Device Details
BNC-SDI Ports
MUX22 can be factory fitted with 0-4 (in a special version up to 8) dual-channel video ports, which are specified at
the time of ordering. Each port can be equipped with a high quality BNC connector, providing 3G/HD/SD-SDI
connectivity.
Two types of dual 3G/HD/SD-SDI modules are available for MUX22:
•
IVT Input Module: Two 3G/HD/SD-SDI BNC reclocked inputs (see description below)
•
IVT Output Module: Two 3G/HD/SD-SDI BNC reclocked outputs (see description below)
OPTOCORE CONTROL SOFTWARE monitors signal quality and strength.
IVT (Intelligent Video Tunnel) Input Module
Two 3G/HD/SD-SDI inputs (BNC) with equalizer, reclocker and two dual fiber output ports. The fiber ports can be
fitted with one dual SFP transmitter for non-redundant transmission or two dual SFP transmitters for redundant
transmission. Redundancy is available only in a point-to-point connection between two MUX22 devices. The fiber
transmitters are internally connected to built-in CWDM/DWDM modules.
IVT (Intelligent Video Tunnel) Output Module
Two 3G/HD/SD-SDI outputs (BNC) with reclocker and two dual fiber input ports. The fiber ports can be fitted with
one dual SFP receiver for non-redundant reception or two dual SFP receivers for redundant reception.
Redundancy is available only in a point-to-point connection between two MUX22 devices. The fiber receivers are
internally connected to built-in CWDM/DWDM modules.
Fiber Ports
Video signals from/to 3G/HD/SD-SDI coaxial interfaces and audio/data signals from the built-in Optocore module
are terminated with SFP fiber ports.
All SFP video fiber ports in a MUX22 device are internally connected to CWDM or DWDM passive multiplexing
module(s) as required for the application. Two external duplex fiber ports (labelled LINK1 and LINK2) should be
used for the external connection of Optocore fiber links to the built-in CWDM/DWDM module. External auxiliary
connections (labelled AUX1 and AUX2) to the multiplexer module(s) can be specified for the connection to an
external device such as a Gigabit Ethernet switch. COM1 and COM2 ports transmit/receive the combined signals
from/to 2 (redundant) CWDM/DWDM modules. All fiber ports are equipped with LC connectors. In case of
MUX22 IVT/IVT each of COM1 and COM2 carry half of video channels, one of AUX and one of LINK.
Multiplexers
The device is equipped with WDM module(s). CWDM (Coarse Wavelength Division Multiplexing) and DWDM
(Dense Wavelength Division Multiplexing) modules are available and will be configured by the manufacturer to the
customers needs. For each SDI signal one wavelength of the WDM module is used, whilst all audio, data and
sync signals are transmitted on the same wavelength utilising Optocore protocol.
Additional auxiliary fiber optic connections (tunnels) can be provided for the connection of third party equipment
(e.g. Ethernet switches) on customer’s request.
IC422 and IC485 - Intercom Ports
Each 4-wire intercom port is complete with a line level input, line level output and a bi-directional RS422 or RS485
(device specific) serial communication link, allowing seamless integration with ClearCom or RTS intercom
systems, on a single RJ45 connector.
The intercom ports are duplicated with a reversed pin out (TO MATRIX and TO PANEL) to allow connections to
intercom matrix frames, user key-panels and interfaces using straight Cat5 cables.
ICAES - AES3 Duplex Ports
Each duplex port provides one fully 32-bit transparent AES3 input and output on a single RJ45 connector,
allowing seamless integration with AES-based intercom systems. Intercom matrix and MUX22 devices need to be
