SFP transceiver module BlueOptics SFP-1G-LX-20KM-EN-BO 1250 Mbit/s Silver

The BlueOptics SFP-1G-LX-20KM-EN-BO 1250 Mbit/s Silver is a single‑port fiber optic SFP transceiver module designed for 1G Ethernet links. It supports a maximum data transfer rate of 1250 Mbit/s and is intended for optical transmission distances up to 20 km. The module has a compact SFP form factor and a lightweight metal housing in silver finish, making it compatible with a wide range of switches, routers and media converters that accept standard SFP modules.

Advantages

This transceiver provides stable single‑mode fiber connectivity for long‑reach links up to 20 km while maintaining low power consumption and a compact footprint. The SFP form factor allows hot‑swappable installation without powering down network equipment, and the metal casing contributes to mechanical durability and heat dissipation. With support for a 1250 Mbit/s line rate, the module is suitable for standard 1G fiber Ethernet deployments.

Suitable for

• Connecting 1G Ethernet switches and routers over single‑mode fiber
• Long‑distance backbone links up to 20 km
• Data center uplinks and campus network interconnects
• Replacing or upgrading existing SFP fiber ports

Key specifications

• Interface type: SFP (small form‑factor pluggable)
• Maximum data transfer rate: 1250 Mbit/s (suitable for 1G Ethernet)
• Optical reach: up to 20 km over single‑mode fiber
• Product colour: silver metal housing
• Weight: approximately 0.02 kg

How to use

Insert the BlueOptics SFP transceiver into an available SFP port on a compatible switch, router or media converter until it engages. Connect a single‑mode fiber patch cable with the appropriate connector type to the transceiver optical interface, ensuring correct transmit/receive alignment. The module is hot‑pluggable; most devices will detect and negotiate link parameters automatically. Verify link status and speed in the network device management interface after installation.

Recommendations

Use single‑mode fiber cables rated for long‑reach applications and keep connectors clean to ensure reliable optical performance. Confirm compatibility with the host device's SFP specifications and firmware; while the module follows standard SFP form factor and speed, checking vendor support reduces potential interoperability issues.
