Description

Miray QSFP28-100G-LR4 is a QSFP28-form factor optical transceiver module designed for 100G Ethernet applications. It supports the 100GBASE-LR4 standard, enabling data transmission over single-mode fiber (SMF) for distances up to 10 kilometers. The module operates at a wavelength of 1310 nm and utilizes duplex LC connectors for optical interfacing. With a power consumption of 3.5W, it offers an energy-efficient solution for high-speed networking needs.

This transceiver is compliant with IEEE 802.3ba standards and the QSFP28 MSA, ensuring compatibility with a wide range of network equipment. It integrates LAN WDM TOSA and ROSA, facilitating reliable long-distance data transmission. The QSFP28-100G-LR4 is idea for data center interconnections, high-performance computing networks, and enterprise core networks that require robust and efficient 100G Ethernet connectivity.

Built for 100G Long-Reach Core Network Performance
This QSFP28-100G-LR4 transceiver is designed for organizations that need stable 100G uplinks across campus, metro, and data center environments, delivering dependable single-mode fiber transmission up to 10 km at 1310 nm. For buyers evaluating products from optical transceiver manufacturers or comparing options used alongside equipment from top network switch manufacturers, this module provides a practical balance of bandwidth, reach, and operational efficiency. Its QSFP28 form factor and duplex LC interface make it well-suited for high-density deployments where every port matters, helping enterprises, telecom operators, and large-scale IT teams expand network capacity without adding unnecessary complexity to the broader network switch and transceiver architecture.

Standards-Based Design with Diagnostics for Stable Operation
The module supports 100GBASE-LR4 transmission in compliance with IEEE 802.3ba, IEEE 802.3bm, and QSFP28 MSA requirements, giving procurement and engineering teams confidence in interoperability across qualified platforms. It uses LAN WDM TOSA and ROSA technology, DFB transmitters, and PIN with SOA receiver design to support data rates up to 103.125 Gbps over G.652 SMF, with power consumption below 3.5W and a bit error ratio of ≤1.00E-12. Integrated DOM/DDM functions provide real-time visibility into temperature, voltage, and optical power, which supports faster fault isolation and more controlled network maintenance. For infrastructure teams already working with an ethernet switch, poe switch, or adjacent optical platforms such as an sfp module, this QSFP28 unit offers a reliable optical layer for high-speed aggregation and backbone links.

Well-Suited for Data Centers, Telecom, and Industrial Network Expansion
In real-world deployment, this 100G LR4 module fits data center interconnects, enterprise core upgrades, telecom transport layers, and high-performance computing environments that require long-distance 100G connectivity with consistent signal quality. It is also relevant to buyers sourcing from industrial ethernet switch manufacturers that need dependable optical links between distribution layers, control networks, or remote facilities using single-mode fiber. By combining standards compliance, low power draw, and digital diagnostics, the module helps reduce operational risk while supporting scalable bandwidth growth in environments where uptime, port density, and predictable performance are key purchasing criteria. For OEMs, system integrators, and network operators, it is an efficient choice for extending 100G services across demanding infrastructure.

Key Advantages

Stable 100G Transport for Core Networks
This transceiver is built for 100GBASE-LR4 transmission over single-mode fiber up to 10 km, which gives network teams a practical way to extend backbone capacity without changing existing QSFP28-based platform design. For buyers comparing products from optical transceiver manufacturers and top network switch manufacturers, this matters because stable optical performance, IEEE compliance, and low bit error rate directly support predictable link behavior in data center, enterprise, and telecom environments where uptime and signal integrity are critical.

Practical Compatibility and Easier Maintenance
With QSFP28 form factor, duplex LC interface, and DOM support, the module is well-suited for structured deployment alongside a network switch, ethernet switch, or other high-density optical platforms. This is a real operational advantage because IT and engineering teams can monitor temperature, voltage, and optical power in real time, helping them identify link issues earlier and reduce maintenance effort. For projects that also involve products from industrial ethernet switch manufacturers, sfp module planning, or uplink design around a poe switch, this level of visibility and standards-based interoperability supports more stable long-term operation.

Use Scenarios

Data Center Interconnect and Aggregation
In data center rows, aggregation cabinets, and core switching areas, operators often need longer-reach 100G links between racks, rooms, or buildings while keeping port density high and power use controlled. This transceiver fits that requirement by providing 1310 nm 100G transmission over SMF up to 10 km through a QSFP28 interface, making it a practical choice for uplinks connected to a network switch from top network switch manufacturers. It is well-suited to this scenario because it combines long-distance optical reach, stable protocol compliance, and DOM-based monitoring for routine operations.

Enterprise Core and Industrial Network Expansion
In enterprise campuses, telecom equipment rooms, and industrial communication environments, network administrators may need to expand backbone bandwidth between control centers, server rooms, or remote buildings where copper links and short-range optics are not sufficient. This module serves as a reliable optical uplink for an ethernet switch deployment, especially when teams are evaluating components from industrial ethernet switch manufacturers or integrating access layers that include a poe switch. It fits this scenario because it provides stable long-distance SMF connectivity, works within common QSFP28 architectures, and offers maintenance-friendly diagnostics that help reduce troubleshooting time.
