Network media converter EFB Elektronik XT-915A — 2-port 10G/1G SFP+ metal housing, blue

EFB Elektronik XT-915A is a compact 2-port network media converter that supports 10G and 1G BASE-X connectivity via SFP+ transceivers. Housed in a blue metal enclosure with compact dimensions (135 × 87.8 × 20 mm) and weighing 0.407 kg, the unit is designed for professional fiber-optic uplinks and media conversion between fiber segments. It is FCC and CE Class A certified for use in enterprise and telecom environments and provides management via web GUI, CLI and SNMP for remote configuration and monitoring.

Advantages

The XT-915A offers two SFP+ fiber ports that enable high-speed 10G links and can also operate at 1G, providing flexible media conversion between single-mode and multi-mode fiber or between PON and Ethernet. Built-in management and security features such as SNMPv3, SSHv2 and TLSv1.2 allow secure remote access and monitoring. Software-based redundant ring support with fast recovery and Link Fault Pass-through enhance network reliability, while SFP digital diagnostic monitoring simplifies transceiver troubleshooting.

Suitable for

• Extending fiber uplinks between switches and routers in enterprise networks
• Media conversion between fiber segments or between PON and Ethernet
• Remote or distributed network locations requiring secure managed devices
• Telecom access sites and FTTx edge deployments supporting IPv4 and IPv6

How to use

Install compatible SFP/SFP+ transceivers into the two SFP+ slots and connect fiber cables according to the network topology. Power the device with the provided 12 V DC adapter and mount the unit on a wall or DIN-rail if required. Use the web interface, CLI or SNMP to configure link speeds, VLANs, QoS and security settings. Enable Link Fault Pass-through and ERPS where needed to integrate the converter into resilient network rings. Monitor SFP parameters through the SFP-DDM feature and collect traps or logs centrally for fault detection.

Recommendations

Use single-mode SFP+ transceivers for long-reach links and multimode modules for short-range connections; verify transceiver compatibility with your fiber type and network equipment. Configure SNMPv3 and TLS/SSHv2 for remote management to reduce security risks. For redundant deployments, enable ERPS and test recovery behavior to confirm the ring recovers within the expected timeframe. Regularly monitor SFP-DDM readings and firmware versions to maintain stable operation.
