Mini-GBIC Dual Wavelength

Mini-GBIC Dual Wavelength

The Mini-GBIC Dual Wavelength is a high‑performance optical transceiver designed to deliver reliable, gigabit Ethernet connectivity over fiber optic links up to ten kilometers. Its compact SFP (Small Form‑Factor Pluggable) form factor makes it ideal for integration into switches, routers, and other networking equipment that requires efficient, low‑profile optical modules.

Key Technical Specifications

• Connector Type: LC – a small form factor connector that offers high density and easy cable management.
• Maximum Transmission Distance: 10,000 meters (10 km) – enabling long‑haul connections between buildings or across campus networks.
• Network Standards: IEEE 802.3 – fully compliant with the standard for Gigabit Ethernet over fiber.
• Maximum Data Rate: 1,000 Mbit/s (1 Gbps) – delivering full gigabit throughput for high‑bandwidth applications.
• Interface Type: SFP – a hot‑swappable module that can be inserted or removed without powering down the host device.
• Transceiver Type: Optical Fiber – utilizing light to transmit data, which provides superior bandwidth and immunity to electromagnetic interference compared with copper cabling.

Dual‑Wavelength Operation

The module operates on two distinct wavelengths: 1550 nm (TX) for transmitting signals and 1310 nm (RX) for receiving. This dual‑wavelength configuration allows the transceiver to function in a single‑mode fiber environment, ensuring minimal signal loss over long distances while maintaining high data integrity.

Compatibility and Integration

The Mini-GBIC Dual Wavelength is engineered to be compatible with a range of networking equipment that supports SFP modules. It can be seamlessly integrated into devices such as switches, routers, and media converters that accept LC‑type optical transceivers. The hot‑swap capability ensures that network administrators can replace or upgrade the module without interrupting service.

Applications

• Enterprise Campus Networks: Connects core switches to distribution layers across multiple floors or buildings.
• Data Center Interconnect: Provides high‑speed links between server racks or between data centers in close proximity.
• Telecommunications Backbone: Supports backhaul connections for telecom operators requiring reliable, long‑reach fiber links.
• Industrial Automation: Enables robust communication in environments where electromagnetic interference could compromise copper cabling.

Design and Build Quality

The module features a ruggedized housing that protects the internal optics and electronics from environmental stressors. Its compact SFP footprint allows for dense packing of transceivers on high‑density network gear, maximizing space efficiency while maintaining optimal airflow and cooling.

Performance Characteristics

With a 10 km reach, the module supports single‑mode fiber deployments that demand low attenuation. The dual‑wavelength design ensures that the transmitted signal at 1550 nm experiences minimal dispersion, while the received signal at 1310 nm benefits from lower chromatic dispersion characteristics of single‑mode fibers.

Installation Guidelines

1. Verify that the host device supports SFP modules and has an LC port available.
2. Power down the host equipment if required by its manufacturer’s guidelines (though most SFPs are hot‑swappable).
3. Insert the Mini-GBIC Dual Wavelength into the LC slot, ensuring a firm click and secure connection.
4. Reconnect power to the host device if it was powered down.
5. Configure any necessary settings on the host device (e.g., link speed, duplex mode) through its management interface.

Operational Considerations

When deploying over long distances, it is essential to use high‑quality single‑mode fiber that matches the module’s wavelength specifications. Proper cable handling—avoiding sharp bends and excessive tension—will preserve signal integrity and extend the life of both the fiber and the transceiver.

Conclusion

The Mini-GBIC Dual Wavelength delivers a blend of high data throughput, long‑reach capability, and compact form factor that is essential for modern networking infrastructures. Its dual‑wavelength operation on LC connectors ensures compatibility with existing fiber deployments while providing the performance required for demanding gigabit Ethernet applications.
