5. Operation temperature: 0 ℃ - 55 ℃ (32˚F - 131˚F)
6. Storage temperature: -20 ℃ - 70 ( ℃ -4˚F - 158˚F)
7. Relative humidity: 5% - 90%
8. TP cable: 10Mbps - Category 3, 4, or 5 UTP
100Mbps - Category 5 UTP
9. FX cable: Multi-mode - 50/125, 62.5/125 or 100/140µm
Single-mode - 8.3/125, 8.7/125, 9/125 or 10/125µm
10. Dimensions: 94mm x 70mm x 26mm (3.7in x 2.8in x 1.0in)
Cautions:
1. This product is suitable for indoor application.
2. Put on the dust cover of fiber interface when not used.
3. It is forbidden to stare at the TX fiber-transfer end with naked eyes.
Troubleshooting:
1. Fail to transmit data: Make sure the UTP distance does not exceed
100m, and the fiber distance does not exceed the maximum distance.
Verify that both nodes are running at the same speed.
2. UTP or Fiber Link LED is not lit: Check the power on the
network device connected to the converter, make sure it is
turned ON. Check the cables, make sure the UTP cable
complies with EIA/TIA 568 specification and fiber optic
cables comply with industry standards.
