Mini-GBIC Dual Wavelength Single‑Mode LC

The Mini-GBIC Dual Wavelength Single‑Mode LC is a compact, high‑performance transceiver module designed for use in fiber‑optic networks that require reliable data transmission over long distances. With its dual‑wavelength capability—1550 nm (RX) and 1310 nm (TX)—this module supports the 1000Base‑LX Gigabit Ethernet standard, as well as Fibre Channel applications. Its LC connector is engineered for single‑mode fiber, enabling signal propagation up to 20 km without significant loss.

Key Technical Specifications

• Connector Type: LC (single‑mode)
• Wavelengths: 1550 nm (receive), 1310 nm (transmit)
• Data Rate: 1 Gbps (1000Base‑LX)
• Maximum Distance: 20 km on single‑mode fiber
• Power Consumption: Low
• Operating Temperature: –25 °C to +70 °C
• Compliance: TAA, RoHS, and other industry standards

Design Features & Advantages

The module’s Mini‑GBIC form factor allows it to fit into a wide range of network equipment, including switches, routers, and media converters. Its dual‑wavelength design eliminates the need for separate transmit and receive modules, simplifying cabling and reducing cost. The LC connector provides a secure, low‑loss interface that is easy to terminate on standard fiber patch panels.

Applications

This transceiver is ideal for:

• Enterprise LANs requiring high‑speed connectivity over long distances.
Data centers where space efficiency and low power consumption are critical.
• Telecommunications infrastructure that demands reliable, single‑mode fiber links.
• Fibre Channel storage networks needing 1 Gbps throughput with minimal latency.

Compatibility & Integration

The module is fully compatible with any network device that supports the Mini‑GBIC interface and adheres to the 1000Base‑LX standard. It can be seamlessly integrated into existing fiber networks without requiring additional adapters or converters.

Installation Guidelines

1. Verify Compatibility: Ensure that the host device accepts Mini‑GBIC modules and supports 1000Base‑LX.
2. Prepare Fiber: Use single‑mode fiber with a core diameter of 9 µm. Clean the LC connector endface with lint‑free wipes before insertion.
3. Insert Module: Align the module’s gold pins with the host device’s slot and gently push until it clicks into place.
4. Tighten Connector: Secure the LC connector using a locking mechanism or spring clip to maintain signal integrity.

Maintenance & Troubleshooting

• Regular Inspection: Check for physical damage, dust accumulation, and proper seating of the module.
• Signal Monitoring: Use an optical power meter to verify that received power remains within acceptable limits (typically –5 dBm to +2 dBm).
• Temperature Checks: Monitor ambient temperature; extreme conditions can affect performance.
• Firmware Updates: If the host device supports firmware upgrades, keep it updated to maintain optimal compatibility.

Performance Highlights

The dual‑wavelength design ensures that the module can simultaneously transmit and receive data without interference. Its low insertion loss (0.5 dB) and high return loss (> 30 dB) guarantee minimal signal degradation over long distances. The 20 km reach makes it suitable for campus networks, branch office connections, and inter‑data‑center links.

Environmental & Safety Considerations

The module complies with TAA (Trade Agreements Act) and RoHS directives, ensuring that it contains no hazardous substances such as lead or mercury. Its low power consumption reduces heat generation, contributing to a more energy‑efficient network environment.

Conclusion

The Mini-GBIC Dual Wavelength Single‑Mode LC delivers reliable, high‑speed connectivity for modern fiber networks. Its compact form factor, dual‑wavelength capability, and long‑reach performance make it an essential component for enterprises seeking to build scalable, cost‑effective optical infrastructures.
