### 4. Functionality
The SFP100B3-SS20-I operates as a bi-directional optical transceiver that enables full-duplex data communication over a single strand of single-mode fiber. It uses wavelength-division multiplexing (WDM) technology to separate transmit and receive signals on different wavelengths—transmitting at 1310 nm and receiving at 1550 nm.
Working Principle:
- The module converts electrical Ethernet signals from the host device (switch, router, or media converter) into optical signals for transmission over fiber.
- At the remote end, a complementary BIDI SFP module (e.g., SFP100B5-SS20-I, TX: 1550 nm / RX: 1310 nm) receives the optical signal and converts it back to electrical form.
- This pairing enables two-way communication over a single fiber core, reducing cabling complexity and cost.
Use Cases and Applications:
- Industrial Ethernet networks
- Intelligent transportation systems (ITS)
- Power substations and utility networks
- Oil and gas field communications
- Factory automation and process control
- Outdoor surveillance and security systems
- Remote monitoring and SCADA systems
Compatibility:
- Compatible with ORing industrial switches, media converters, and routers supporting SFP slots.
- Interoperable with other standard-compliant SFP devices from major vendors.
- Requires pairing with a complementary BIDI SFP module (TX/RX wavelength reversed) for proper operation.
