● If the distance between the FDX and transmitter/receiver is 100 m/328.08 ft. or less, a cable joint can be
used. Up to two cable joints are allowed and joints supporting Cat6A (10GBase-T) are recommended.
Note:
If there is a problem in the transmission path, video or audio may be interrupted. Please check the
items above. If the problem still cannot be resolved, shorten the length of the HDBaseT cable.
■
Optic fiber cable [Read this instruction when mounting an optical I/O slot board.]
To ensure the best performance of the FDX, select the appropriate optical fiber cable for a long- distance
transmission and connect it correctly.
● Use a duplex fiber or two simplex fiber cables with LC connectors at both ends.
To polish connectors:
For SFP module for multimode: PC polishing is recommended.
For SFP module for singlemode: UPC polishing is recommended.
Note:
APC polishing is not supported.
● Make sure that the fiber optical cable to be connected between the FDX and transmitter/receiver
meets the standard of the desired extension distance.
● Extension distance varies depending on attenuation of the fiber, connector and other contact portions.
● Before inserting or removing the fiber, make sure to first turn the FDX off and not to touch the ends of
the fiber. Clean them up before inserting the cable again.
♦ Simplex fiber and duplex fiber:
Simplex fiber has an optic fiber and a connector at both ends while duplex fiber has two fibers and two
connectors. The duplex fiber cable is recommended for the FDX, but signals can be transmitted using two
simplex fiber cables.
♦ LC connector:
One of connectors for fiber optical cables. (Example: SC connector, FC connector, ST connector, MU
connector)
■
SFP module [Read this instruction when mounting an optical I/O slot board.]
The fiber type and extension distance to be used vary depending on the SFP module.
[Table 5.1] Specifications of standard SFP modules
* Some SFP modules for singlemode can extend the transmission distance up to 30 km with OS1.
Please contact us if needed.
Notes:
● Plug the dust cap to the fiber optical cable if you do not use it.
● Do not use the SFP module for other devices. Do not connect the optic fiber cable that is connected to
other devices to the SFP module; otherwise, the SFP module may be broken. The maximum receiving
optical level of the SFP module in the FDX is 0 dBm
● If you need to replace the SFP module, please contact us.
