BlueOptics BO15C4931640D compatibele Synology SFP-BXD43-40KM SFP-transceiver, LC Simplex, 1000BASE-BX, 40 km

The BlueOptics BO15C4931640D is a high-performance SFP transceiver designed for compatibility with Synology SFP-BXD43-40KM and MSA compliant devices. It enables reliable Gigabit Ethernet connectivity over single-mode fiber at distances up to 40 km. This BiDi (Bi-directional) transceiver uses LC simplex connectors and operates at 1490 nm transmit / 1310 nm receive wavelengths, making it ideal for point-to-point fiber optic networks.

Advantages

Cost-effective alternative to OEM modules with full compatibility and MSA compliance. Hot-pluggable design simplifies installation and maintenance. Supports Digital Diagnostic Monitoring (DDM/DOM) for real-time performance monitoring. Low power consumption (<1.0 W) reduces energy costs. Robust DFB laser and APD receiver ensure stable performance over long distances.

Suitable for

• Gigabit Ethernet networks requiring 1000BASE-BX standard
• Single-strand fiber applications (BiDi technology)
• Long-haul connections up to 40 km
• Synology NAS systems and other MSA-compatible switches/routers
