5.2 Precautions
Read and follow the precautions below before connecting to external devices.
5.2.1 Installation
●Before connecting a cable to the OPF or to an external device that is connected to the OPF,
eliminate static electricity by touching metallic item or the like.
●Do not place the transmitter on top of the receiver and vice versa.
●Do not block vent holes.
Keep enough space (3 cm/1.18 inches or more) around the product.
●Do not install the OPF-H2000 in closed space.
If you have to install the product to an EIA rack mount in closed space, add a ventilation to keep
the ambient temperature of 40 degrees C/104 degrees F or less. (Exception: Installing to IDK’s
Quarter rack, RM-42HQ) If inadequately vented, the life of parts may be shortened and operations
may be affected.

5.2.2 Cabling
●Read the instruction manuals of the external devices carefully.
●Turn off the OPF-H2000 before connecting cables.
●Secure the HDMI cable using an attached cable clamp in order to prevent it from falling off this
device.

5.2.3 Fiber optic cable
To ensure the best performance of a fiber optic cable for a long-haul transmission, select and connect the
proper fiber optic cable correctly.
●Connect a fiber optic cable to the OPF as follows:
Optical output connector of the transmitter & optical input connector of the receiver
Optical input connector of the transmitter & optical output connector of the receiver
●To polish connectors:
For SFP+ module for multi-mode: PC polishing is recommended.
For SFP+ module for single-mode: UPC polishing is recommended.
Note: APC polishing is not supported.
●Extension distance varies depending on attenuation of the fiber, connector and other contact portions.
●Do not exceed the allowable tension and bend radius; otherwise it may affect the performance of the
product and the product life cycle.
●Make sure to plug the dust cap to the both ends except for when connecting it to the product. Do not leave
a fiber optic cable without the dust cap if you do not use the cable in order to prevent scratches and dirt.
●Before connecting a fiber optic cable to the OPF, make sure there is no scratch or dirt on the ends of the
connector; otherwise, the OPF may not work correctly. Clean it up if it is dirty.
Left: without dust cap
Right: with dust cap Before cleaning After cleaning
5.2.4 SFP module
The fiber type and extension distance to be used vary depending on the SFP module.
* Some SFP modules for single-mode can extend the transmission distance up to 10 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 fiber optic cable that is connected to
other devices to the SFP module; otherwise, the SFP module may be broken.
●If you need to replace the SFP module, please contact us.

5.4 Typical application example
Digital video and audio are transmitted from the Blu-ray disc player to the transmitter. The transmitter sends
those signals to the receiver over a fiber optic cable. The receiver outputs the received video and audio
signals to the projector from the HDMI output connector.
Peripheral device control (such as projectors) and Ethernet communication will be available by using a control
device (such as PCs).
Note: The OPF-TH2000 must be paired with OPF-RH2000. The OPF-H2000 cannot be connected to an I/O
slot board of the FDX series or other models of the OPF series.
