LOGILINK SFP transceiver-module 1.25G SM 20 km LC

Extending Gigabit Ethernet over single-mode fiber for up to 20 kilometres, the LOGILINK SFP002 is a reliable and cost-effective SFP transceiver that delivers consistent performance in enterprise networks, campus backbones, and metropolitan-area links. Its LC duplex interface and 1310 nm FP laser make it a direct fit for network switches, routers, and media converters equipped with standard SFP cages.

Highlights

• 1.25 Gbps data rate, compatible with IEEE 802.3z 1000BASE-LX/LH
• Single-mode fiber support (OS1/OS2) with 20 km maximum distance
• LC duplex connector, hot-pluggable SFP MSA form factor
• Digital diagnostic monitoring (DDM) for real-time optical parameters
• Wide operating temperature range (0°C to 70°C) and low power consumption (<1W)

In daily use

The SFP002 is ideal for connecting distant network segments where multimode fiber would be ineffective or where repeaters add unnecessary cost and complexity. Insert it directly into an SFP cage, and it will automatically negotiate with the switch fabric. DDM-capable equipment can track temperature, voltage, and optical power to ensure stable operation. For fibre-to-the-office or inter-building links, this module provides a clean, cost-efficient upgrade path from 100 Mbps to 1 Gigabit per second.
