### 4. Functionality

The SFP1G‑EZX120 functions as a modular optical transceiver that converts electrical Gigabit Ethernet signals into optical signals for transmission over single‑mode fiber. It uses a 1550 nm laser transmitter and a high‑sensitivity photodiode receiver to achieve long‑distance communication.

Operating Principle:
- The transmitter (TX) converts electrical data signals from the host device into optical pulses at 1550 nm wavelength.
- The receiver (RX) detects incoming optical signals and converts them back into electrical signals for the host interface.
- The module interfaces with the host system via a standard SFP electrical connector, supporting hot‑swap capability.

Use Cases and Applications:
- Long‑haul Gigabit Ethernet backbone links between data centers or campuses.
- Metropolitan area networks (MAN) and telecom aggregation nodes.
- Industrial automation networks requiring extended fiber runs.
- Surveillance and transportation systems with remote network nodes.
- Utility and energy sector communication backbones.
- Compatible with Ethernet switches, routers, and media converters supporting SFP slots.

Compatibility:
- Fully compatible with ORing industrial switches and media converters.
- Interoperable with third‑party SFP‑compliant devices from Cisco, HP, Juniper, and others.
- Supports standard LC duplex single‑mode fiber patch cords (9/125 µm).
