Connectors and Cables
SD/HD/3G-SDI Ports
Use 75
Ω
coaxial cable with BNC connectors. The cable and connectors used should comply with the digital
SD/HD/3G-SDI transmission standards. The maximum cable length is dependent on the bandwidth of the signal
(SD, HD or 3G) and the specifications and quality of the cable and connectors.
Optical Connections
Each MUX22 features internal and external fiber connections. The number of connections depends on the
application and will be customized at the time of manufacturing. Each electrical 3G/HD/SD-SDI channel is
converted into a different wavelength using internal SFP transceivers and WDM modules.
For video applications:
Standard single mode transmitters can be used for applications requiring cable lengths of up to 10 km. For longer
cable runs transmitters with higher output power are available (max. cable length without reclocking the signal is
80km), please contact the BroaMan technical team for requests.
The total optical loss should be less than 6dB between transmitter and receiver.
For Optocore network:
Multimode or singlemode transceivers are available for the externally accessible Optocore SFP ports and can be
changed by the user. Maximum cable length for multimode is 700m, for singlemode 80km. Optocore is equipped
by default with singlemode 1Gbit 10km transceiver.
The total optical loss should be less than 6dB between transceivers.
SANE Ports
Use standard, fully wired, twisted pair cable (Cat 5, Cat 5e, Cat 6) terminated with RJ-45 connectors. SANE
utilizes all four pairs of the Cat 5 cable, two pairs for standard Ethernet transmission and two pairs for the SANE
synchronous audio transport. A SANE cable shall not exceed a total cable distance of 100 m.
Auxiliary Ports – RS485/GPIO/RS422
Each of the four (RS485)/eight (GPIO)/four dual RS422 channels requires a shielded twisted pair cable.
If two or more channels are wired to the same cable a common braided shield should enclose the pairs.
RS232 Connection
Use a standard shielded RS232 cable.
Connector Hood Quality
Locking screws for D-Sub connectors should be compatible with 4-40 UNC. Care should be taken in selecting the
right type of connector hoods in order to fulfil the requirements of EMI-radiation directives. Full metal connector
hoods should be used, approved acc. to VDE 0871, FCC 20780 and EMC directive 2004/108/EG, providing
attenuation > 40 dB between 30 MHz up to 1 GHz. The shield of the cable should have contact to the connector
hood
.
Please note:
SFP fiber transceivers are application specific and must match the coaxial
interface
The user must not change internal SFP transceivers. Please refer to warrnaty
conditions.
