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.

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.
