Transceptor CBO QSFP28-100G-LR4 módulo de fibra ótica 100G LR4

The Transceiver CBO QSFP28-100G-LR4 100G LR4 fiber optic module is a QSFP28 form-factor 100 Gigabit Ethernet transceiver designed for long-reach single-mode links. It supports 4-lane LR4 transmission over single-mode fiber, enabling high-capacity connections between data center equipment and carrier-grade networks. The module is intended for use in server uplinks, aggregation switches and metro interconnects where long-distance single-mode performance and a compact QSFP28 footprint are required.

Advantages

This QSFP28 LR4 module provides 100G aggregated bandwidth in a compact, hot-pluggable QSFP28 package compatible with standard LR4 interfaces. Its single-mode LR4 design delivers extended reach for inter-rack, inter-data center and metro links while maintaining industry-standard alignment for straightforward installation. The transceiver's multi-lane architecture and compact form factor reduce port density constraints and simplify upgrades from 10/40G to 100G infrastructure without requiring significant chassis changes.

Suitable for

• 100 Gigabit Ethernet server uplinks
• Aggregation and core switches in data centers
• Metro and long-reach carrier links over single-mode fiber
• Interconnects between sites and data center fabrics

Key specifications

• Form factor: QSFP28
• Nominal data rate: 100 Gbps (4 × 25 G lanes)
• Optical interface: LR4, 4-lane single-mode fiber transmission
• Wavelength: coarse wavelength-division multiplexing across four lanes
• Reach: designed for long-reach single-mode links suitable for metro and data center interconnects
• Connector type: compatible with standard single-mode fiber connectors (LC with breakout/fanout as required)
• Hot-pluggable QSFP28 package for easy insertion and removal

How to use

Insert the QSFP28 module into a compatible QSFP28 port on a switch, router or server NIC while the host is powered on or according to the host vendor's recommendations for hot-plug operation. Connect appropriate single-mode fiber cabling and any required LC duplex or MPO-to-LC breakout assemblies depending on the port wiring. Verify link status and negotiated rate through the host device management interface and confirm correct lane mapping if the system requires per-lane configuration. Follow standard handling precautions for optical transceivers, including dust caps for connectors and ESD protection during installation.

Recommendations

Use factory-tested single-mode fiber and clean connector end-faces to maintain optimal optical loss budgets. Match the module with LR4-capable ports and verify compatibility with the host vendor's supported transceiver list when possible. For long-distance deployments, plan for fiber attenuation and connector/splice loss in the link budget and monitor link performance through device diagnostics.
