### 4. Functionality

The SFP100B5-MM-I operates as a bi-directional optical transceiver, enabling simultaneous transmission and reception of Ethernet data over a single optical fiber. The module integrates a 1550 nm laser transmitter and a 1310 nm photodiode receiver within a compact SFP housing. When paired with a complementary transceiver (such as SFP100B3-MM-I, which transmits at 1310 nm and receives at 1550 nm), the two modules form a full-duplex optical link.

Typical Use Cases:
- Industrial Ethernet switches and routers
- Media converters and fiber extenders
- Transportation and railway communication systems
- Outdoor surveillance and control networks
- Factory automation and SCADA systems
- Power substation communication links

Compatibility:
- Fully compatible with standard SFP slots in ORing and third-party networking devices.
- Interoperable with other 100 Mbps BIDI SFP modules using complementary wavelength pairs.
- Supports plug-and-play installation with automatic link detection.
