------------------------------------------------------------

6. INSTALLATION & SETUP
• Installation steps:
1. Ensure the host device is powered on or off (SFPs support hot-swapping).
2. Insert the module into the SFP port until it clicks.
3. Attach a single-mode simplex LC fiber patch cable.
4. Ensure the far-end device uses a complementary BIDI SFP (TX/RX reversed).
5. Verify link indicators on the host device.

• Requirements:
– 9/125 µm single-mode fiber
– Opposite wavelength transceiver at the far end (e.g., SFP1GB5-LX20-I)
– Clean fiber connectors for optimal performance

• Configuration:
– No configuration needed on the module itself
– Link speed auto-negotiated at 1Gbps depending on host device capabilities
– Recommended to add optical attenuators for short-distance fiber (<5km) to avoid receiver saturation, as noted in ORing’s documentation

------------------------------------------------------------

7. PERFORMANCE & CAPABILITIES
• Supports stable Gigabit Ethernet over long distances (20 km)
• Maintains reliable operation from -40°C to +85°C, making it suitable for harsh industrial environments
