6.2.2 Fiber optic cable
The OPF-H2000 can reach their full potential by selecting appropriate fiber optic cables for long-haul
extension and installing the cable correctly.
・
Connect a fiber optic cable to the OPF-H2000 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+ optical transceiver for multimode
: PC polishing is recommended.
For SFP+ optical transceiver for singlemode : UPC polishing is recommended.
Note:
APC polishing is not supported.
・
Transmission distance varies depending on attenuation of the fiber, connector and other contact portions.
・
Make sure not to exceed the allowable tension and bend radius of fiber optic cable or the performance of
the product and the life of the fiber optic cable may be affected.
・
Plug the dust caps to both faces of the fiber optic cable when connecting the fiber optic cable and when not
in use
・
Before inserting a fiber optic cable, make sure there is no damage or dirt on the end-face of the optical
connector. Clean up it or OPF-H2000 may not operate correctly.

6.2.3 SFP+ optical transceiver
The fiber type and transmission distance vary depending on the SFP+ optical transceiver.
[Table 6.1] Specification of standard SFP+ optical transceiver
* The lasers in these models meet class1.
・
When no fiber optic cable is connected, plug dust caps.
・
Do not use the SFP+ optical transceiver for other products. Also, do not connect fiber optic cables that is
connected to other products to the SFP+ optical transceiver or the SFP+ optical transceiver may be
damaged.
・
If you need to replace the SFP+ optical transceiver, please contact us.
