Modulo dual-rate QSFP28 LQ-LW112-LR4C: modulo da 10 km per DCI e OTN

★ Dual-Rate QSFP28 Transceiver Introduction

In the rapidly evolving landscape of data center architecture and metro networks, operators face a constant challenge: how to scale bandwidth efficiently while maintaining flexibility for different protocol standards. As traffic from cloud applications and AI workloads explodes, the need for robust 100G solutions is greater than ever.

Entra in scena il LQ-LW112-LR4C, a powerhouse optical transceiver designed to solve these exact challenges. This dual-rate QSFP28 transceiver offers a seamless bridge between Ethernet and Transport networks, providing a future-proof solution for high-speed connectivity.

★ The Power of Dual Rate: 100GBASE-LR4 and 112GBASE-OTU4 in One Module

The defining feature of the LQ-LW112-LR4C is its versatility. Unlike standard transceivers that are locked to a single protocol, this module is engineered to support A doppia velocità operation.

100GBASE-LR4: Ideally suited for standard Ethernet switches and router uplinks within data centers or campus backbones.
112GBASE-OTU4: Fondamentale per Reti ottiche di trasporto (OTN). The OTU4 rate includes the necessary overhead for correzione automatica degli errori (FEC) and management in long-haul transport systems.

By combining these two capabilities, the LQ-LW112-LR4C becomes a universal tool for network engineers, capable of acting as a client-side interface for both standard Ethernet switches and OTN WDM equipment.

★ Technical Deep Dive: Key Specifications for 10km Reach

Built on the industry-standard QSFP28 fattore di forma, this module is optimized for high density and low power consumption. It utilizes four lanes of LAN WDM wavelengths in the 1310nm range to achieve a reach of up to 10 km over Single-Mode Fiber (SMF).

Here is a quick look at the technical specifications:

★ Simplify Your Inventory with the Dual-Rate QSFP28 10km

From an operational standpoint, the 100G/112G dual-rate capability translates directly into cost savings. Instead of stocking separate SKUs for Ethernet links and OTN transponders, procurement managers can standardize on the LQ-LW112-LR4C.

This consolidation simplifies inventory management, reduces the risk of ordering the wrong part, and allows for easier sparing strategies. Whether you are lighting up a new QSFP28 DCI solution or expanding a metro ring, one module covers both bases.

★ Ensuring Reliability with Digital Optical Monitoring (DOM)

Network visibility is critical for maintaining Service Level Agreements (SLAs). The LQ-LW112-LR4C features integrated Monitoraggio ottico digitale (DOM), fully compliant with industry standards.

DOM allows network administrators to monitor critical parameters in real-time via the I2C interface, including:

Potenza di uscita del trasmettitore
Receiver input power
Temperatura del modulo
Corrente di polarizzazione del laser
Rispetta rigorosamente gli standard di settore:

This level of insight allows for proactive maintenance, helping teams identify degrading fiber links or potential hardware issues before they result in a network outage.

★ A Cost-Effective 100G/112G DCI and Metro Solution

Upgrading your optical infrastructure doesn’t have to be complicated. The LQ-LW112-LR4C delivers the perfect balance of performance, reach, and protocol flexibility.

Whether you are connecting data centers across a city or linking switches across a large campus, this 100GBASE-LR4 and 112GBASE-OTU4 transceiver ensures your network is ready for the bandwidth demands of tomorrow.
