BlueOptics BO15C4931620D Compatible Synology SFP-BXD43-20KM SFP Transceiver, LC Simplex, 1000BASE-BX, 20 km

The BlueOptics BO15C4931620D is a high-performance SFP transceiver designed to be fully compatible with Synology SFP-BXD43-20KM. It operates at 1.25 Gbps over single-mode fiber, supporting 1000BASE-BX Ethernet standards. With a reach of up to 20 km and LC simplex connector, this BiDi transceiver uses 1490 nm for transmit and 1310 nm for receive wavelengths. It supports Digital Diagnostic Monitoring (DDM/DOM) for real-time performance monitoring and is hot-pluggable for easy installation. Ideal for Gigabit Ethernet networks, this MSA-compliant module ensures reliable connectivity in enterprise and data center environments.

Advantages

Cost-effective alternative to OEM modules with guaranteed compatibility. Low power consumption (<1.0 W) reduces energy costs. DDM/DOM support enables proactive network management. Hot-pluggable design minimizes downtime during upgrades or replacements.
