5.3 Fiber optical cables for long distance transmission
Use correct fiber optical cables to maximize the performance of the OPF-H1000.
● 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 transmitter and 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 OPF-H1000 off and not to touch the ends
of the fiber. Clean up the fiber before inserting it again.
♦
Simplex fiber and duplex fiber
Simplex fiber has an optical fiber and a connector at both ends while duplex fiber has two fibers and
two connectors. The duplex fiber cable is recommended for OPF-H1000, 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)
5.4 SFP (Small Form-factor Pluggable) module
The fiber type and extension distance to be used vary depending on the SFP module.
[Table 0.1] 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:
● Use only the supplied SFP module to ensure the best system performance and reliability.
● Plug the dust cap to the fiber optical cable if not connecting the cable.
● Pull the lever of the SFP module to remove it. Lock the lever and push it into until it clicks to attach the
module.
