Connectors and Cables
Optical Connection
Multimode transceivers connected using a 50
µ
m OM3 fibre cable can be used for applications requiring cable
lengths of up to 700 m (worst case).
Single mode transceivers connected using a 9
µ
m fibre cable can be used for applications requiring cable lengths
of up to 70 km (worst case).
The total optical loss should be less than 6dB between transceivers.
For portable applications, such as touring and other temporary installations, ruggedized HMA Expanded Beam
Connectors, mounted on 1 RU panels and portable cables on cable drums are available.
Please refer to the Product Brochure available at

MADI Ports
The MADI-interfaces are equipped with standard BNC 75
Ω
- connectors. The applied coax cables should have
the 75 Ω characteristic impedance.
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.
Principal and Auxiliary Ports
Each of the four 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.
USB-Connection
Use a USB-A to USB-B cable between PC and Optocore device.
LAN-Connection
Use standard twisted-pair-cable (Cat-5, Cat-6) with RJ-45 connector.
Word Clock-Connection
Use 75
Ω
-coaxial-cable with BNC-connector.
Video-Connection
Use 75
Ω
-coaxial-cable with BNC-connector.
Mains-Connection
Standard power cords with IEC C13 connectors.
