Fiber GBIC module ProBase GBIC-DF-1310-20 1310 nm, dual fiber, 20 km

ProBase GBIC-DF-1310-20 is a dual-fiber GBIC optical transceiver operating at a wavelength of 1310 nm and designed for single-mode fiber links up to 20 km. The module provides gigabit connectivity for network equipment such as switches, routers and media converters and supports hot-pluggable installation to simplify upgrades and maintenance without powering down devices.

Advantages

The transceiver delivers stable gigabit transmission over long-distance single-mode fiber, with a form factor compatible with GBIC ports. Its dual-fiber design separates transmit and receive channels for reliable full-duplex communication. Hot-pluggable operation reduces downtime during replacement or expansion, while industry-standard optical parameters ensure interoperability with a wide range of compatible network devices.

Suitable for

• Long-distance links between network switches and routers within campus or metropolitan area networks
• Connecting media converters and fiber access equipment to switch uplinks
• Upgrading copper uplinks to gigabit fiber for higher bandwidth and lower latency
• Redundant fiber paths and link aggregation in enterprise networks

Key specifications

• Wavelength: 1310 nm
• Fiber type: single-mode (dual-fiber)
• Maximum transmission distance: up to 20 km
• Data rate: gigabit (1 Gbps)
• Connector type: duplex optical connector (compatible with standard LC/SC interfaces depending on cage/adapter)
• Interface form factor: GBIC (Gigabit Interface Converter)
• Operation: hot-pluggable

How to use

Install the GBIC module into a compatible GBIC slot on the network device by aligning the module with the slot and inserting it until it seats securely; no additional tools are required. Connect single-mode fiber patch cords to the transmit and receive connectors according to the device labeling. Verify link status using the device LEDs or management interface and configure the interface speed and duplex settings if necessary. To remove the module, power down the port if recommended by the device manual, unlock any retention mechanism and gently extract the module.

Usage recommendations

Use single-mode fiber patch cords and maintain proper connector cleanliness to ensure optimal optical performance. Observe manufacturer guidelines for supported devices and environmental conditions. For runs approaching the 20 km limit, verify link margin and consider using fiber testing tools to confirm signal quality before deployment.
