🧰 Key Features
Form Factor: SFP (hot-pluggable) — easily inserted or removed from network switches, routers, or media converters without powering down.
Data Rate: Up to 1.25 Gbps (1000BASE-LX Ethernet).
Wavelengths:
• Transmit (TX): 1550 nm
• Receive (RX): 1310 nm — over a single fiber cable.
Connector Type: Simplex LC (BIDI LC) — uses only one fiber strand for both TX and RX.
Maximum Reach: Up to 20 km over single-mode fiber (SMF).
Digital Diagnostics (DDM/DOM): Supported — allows real-time monitoring of optical power, temperature, and other operating parameters.
Power Consumption: Low power use — typically ≤ 1.5 W.
Standards & Compliance: Compliant with IEEE 802.3z Gigabit Ethernet and SFP industry standards (SFF-8472, SFF-8431, SFF-8432, RoHS).
🚀 How It Works
BiDi SFP modules like this send and receive optical signals over a single fiber strand by using two different wavelengths — in this case, 1550 nm for transmission and 1310 nm for reception. To establish a working link, you pair this module with its counterpart (GE-SFP-LX20-SM1310-BIDI) at the other end of the fiber.
📍 Typical Uses
✔ Gigabit Ethernet links between buildings, data centers, or campuses
✔ Long-distance fiber uplinks where fiber count is limited
✔ Network environments where using only one fiber strand reduces cabling cost and complexity
