Lancom Systems SFP-BiDi1550-SC1 SFP fiber optic transceiver 1000 Mbit/s, silver

The Lancom Systems SFP-BiDi1550-SC1 SFP fiber optic transceiver is a compact module designed for 1 Gbps fiber applications. It supports single-fiber BiDi operation using an SC connector and is intended for use with devices that accept SFP modules, providing a silver metal housing and compatibility with Gigabit Ethernet links. The module enables flexible fiber connections for switches, routers, and firewalls that have SFP ports and require a BiDi SFP transceiver.

Advantages

This transceiver enables bidirectional data transmission over a single optical fiber by using two separate wavelengths. It supports full-duplex operation at up to 1000 Mbit/s and is hot-pluggable for in-service replacement without powering down the host device. The module is suitable for single-mode fiber links and includes support for digital diagnostic monitoring (DDM) to monitor operating parameters.

Suitable for

• Gigabit Ethernet uplinks and fiber backbone segments
• Switches, routers, and firewalls with SFP ports that require BiDi operation
• Single-mode fiber links where a single-fiber BiDi solution reduces cabling
• Network environments that benefit from hot-swappable transceivers

Key specifications

• Interface: SFP module form factor
• Data rate: up to 1000 Mbit/s (1 Gbps)
• Connector type: SC (single connector)
• BiDi operation: single-fiber transmit and receive on two wavelengths
• Fiber type supported: 9/125 µm single-mode fiber
• Typical link reach for single-mode fiber: up to 20 km (dependent on fiber and link conditions)
• Operational mode: full duplex
• Hot-pluggable: supports insertion and removal during system operation
• Monitoring: supports Digital Diagnostic Monitoring (DDM)

How to use

Install the SFP-BiDi1550-SC1 into a compatible SFP port on your switch, router, or firewall while the device is powered on or off; the module is hot-pluggable. Connect the SC-terminated single-mode fiber cable to the transceiver, ensuring correct fiber routing and bend-radius compliance. Configure the host device for a 1 Gbps SFP link as required by your network equipment and verify link status through the device management interface and the transceiver’s DDM readings if available.

Recommendations

Use single-mode 9/125 µm fiber with appropriate SC connectors and verify that the connected peer transceiver supports the complementary BiDi wavelength pair. Observe manufacturer guidelines for ESD protection during handling, maintain proper fiber cleanliness for optimal optical performance, and consult the host device documentation for supported transceiver models to ensure full compatibility.
