Transceptor óptico Zyxel QSFP28 100G QSFP100G-LR4-ZZ0101F 1310nm Long Range

The Zyxel QSFP28 100G QSFP100G-LR4-ZZ0101F 1310nm Long Range optical transceiver is a 100 Gigabit QSFP28 multimode module designed for long-range single‑mode fiber links. It delivers 100GbE connectivity over optical transport at 1310 nm wavelength and is intended for installation in QSFP28-compatible switches and routers. The module supports LR4-class optics for extended reach, enabling high-capacity links between data centers, aggregation nodes and metropolitan backbone sites while maintaining protocol transparency for Ethernet and related transport formats.

Advantages

This transceiver provides high-density 100GbE bandwidth in a compact QSFP28 form factor, enabling efficient space and power usage in rack environments. Operating at 1310 nm with LR4 optics, it supports long-distance single-mode fiber transmission suitable for backbone and metro links. The device is interoperable with standard LR4-compatible equipment, supports hot-plug installation in QSFP28 ports, and is designed for stable optical performance and low error rates across supported distances.

Suitable for

• Data center interconnects and fiber links between server rooms
• Aggregation and core network links in carrier and service provider networks
• Metropolitan area backbone and long-haul campus connections
• Upgrading existing infrastructure to 100GbE without replacing switching platforms

Key specifications

• Interface: QSFP28 form factor for 100 Gigabit Ethernet
• Wavelength: 1310 nm optical transmission
• Fiber type: Single-mode fiber (SMF)
• Optical class: LR4 long-range transmission
• Supported link distances: long-reach single-mode fiber spans (vendor-specific reach depends on fiber and channel conditions)
• Hot-pluggable operation for in-service installation

How to use

Install the transceiver into a compatible QSFP28 port on switches or routers following the host equipment manufacturer’s insertion procedure. Connect single‑mode fiber using appropriate LC duplex or MPO cabling as required by the LR4 interface and ensure proper fiber routing and bend radius to maintain signal integrity. Verify link status via the host device management interface and monitor optical levels and error statistics during initial commissioning and regular operation.

Recommendations

Use certified single‑mode fiber with controlled connector cleanliness and compliant patching practice to ensure reliable long‑range operation. Confirm compatibility with the target switch or router and review optics support matrices for LR4 modules. Monitor SFP diagnostics where available and perform routine inspection of connectors and fiber paths to minimize attenuation and maintain stable 100GbE links.
