5. FAQ

What is an LGX Optical TAP Module?

An LGX Optical TAP Module provides multiple optical monitoring channels within a compact module format. It enables access to optical power for monitoring or test equipment while minimizing disruption to live network traffic.

The GracyFiber version supports 4CH and 8CH configurations with MTP®/MPO interfaces.

Does the LGX TAP Module support both single-mode and multimode fiber?

Yes. According to the supplied parameter table:

• Single Mode: 1260–1650 nm
• Multimode: 850 ±50 nm

The listed multimode fiber options are OM3, OM4, and OM5.

What tap ratios are available?

The supplied specification includes the following ratio pairs:

• 5% / 95%
• 20% / 80%
• 30% / 70%
• 40% / 60%
• 50% / 50%

Insertion loss varies according to the tap ratio, optical mode, and whether the module is 4CH or 8CH.

What interface does the module use?

The supplied product specification lists:

MPO / MTP®

The exact connector gender, polish type, fiber count, and polarity are [Need confirmation].

Can the fiber length and connector configuration be customized?

Yes. The supplied documentation explicitly states that fiber length, coating, and connector options can be customized.

8. Detailed Product Description

The GracyFiber LGX Optical TAP Module integrates multiple optical monitoring channels into a compact rack-oriented module. It is designed for applications where several fiber links need to be monitored simultaneously without repeatedly disconnecting live network connections.

Available in 4CH and 8CH configurations, the product provides independent tap channels within a single 109 × 118 × 35 mm housing and uses MTP®/MPO interfaces for high-density fiber connectivity.

Both single-mode and multimode optical networks are supported. The SM version covers 1260–1650 nm, allowing monitoring across a broad telecom wavelength range. The multimode version operates at 850 ±50 nm and supports OM3, OM4, and OM5 fiber according to the supplied parameter sheet.

Several optical tap ratios are available. The choice of ratio determines how optical power is distributed between the monitored and remaining optical paths. For example, the supplied specification includes asymmetric 5/95, 20/80, 30/70, and 40/60 configurations as well as an equal 50/50 configuration.

The module is designed for integration with external monitoring and diagnostic equipment. The source specifically lists OTDR, OSA, and optical power meter integration, as well as monitoring of 100G, 400G, and 800G data center links.

This combination of multi-channel monitoring, high-density MTP®/MPO connectivity, and modular rack integration makes the LGX TAP Module relevant where continuous optical visibility is required across multiple links.

9. Application Scenario

Application 1 — 100G / 400G / 800G Data Center Monitoring

High-speed data center links may require continuous optical-power monitoring for commissioning, troubleshooting, or link-health analysis.

A 4CH or 8CH LGX TAP Module allows multiple optical paths to be monitored within a single compact module. The supplied documentation specifically identifies 100G / 400G / 800G data center monitoring as an application.

Application 2 — OTDR, OSA & Power Meter Integration

The monitoring ports can provide optical access for test and measurement equipment including:

• OTDR
• Optical Spectrum Analyzer
• Optical Power Meter

These integrations are explicitly listed in the source documentation.

Application 3 — 5G Fronthaul & Edge Networks

5G fronthaul and edge-network links may require optical power verification and ongoing diagnostics across several fiber channels.

The compact multi-channel module provides centralized optical access for these monitoring functions, and 5G fronthaul / edge networks are specifically listed as target applications.
