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

CBO QSFP28-100G-LR4 100G LR4 is a fiber optic transceiver in QSFP28 form factor designed for long-reach single-mode fiber links. It supports 100 Gigabit Ethernet applications and is intended for high-speed data transmission in data centers, telecom trunks and campus networks. The module provides hot-pluggable installation and interoperability with LR4-compatible ports to enable reliable long-distance connectivity over single-mode fiber.

Advantages

This QSFP28 LR4 transceiver offers 100 Gbps aggregate bandwidth in a compact QSFP28 package, enabling high-density port deployment. The single-mode LR4 design extends reach for long-haul links while maintaining signal integrity and low power consumption. Hot-pluggable capability simplifies maintenance and replacement without powering down systems, and adherence to LR4 optical interface characteristics ensures compatibility with equipment that supports standard 100G LR4 optics.

Suitable for

• 100 Gigabit Ethernet links between data center switches and aggregation devices
• Long-reach single-mode fiber connections for metro and campus backbone networks
• Telecom trunk lines and service provider interconnects requiring LR4 optics

Key specifications

• Form factor: QSFP28
• Nominal data rate: 100 Gbps
• Optical interface: LR4 for single-mode fiber
• Reach: Designed for long-reach single-mode links (LR4 class)
• Connector type: LC (quad) compatible
• Hot-pluggable module for in-field replacement
• Power consumption: low-power QSFP28 class (typical for LR4 optics)

How to use

Install the CBO QSFP28-100G-LR4 into a compatible QSFP28 port on a switch, router or transponder while the system is powered on, using the module's latch mechanism to secure it. Connect single-mode fiber using LC duplex/quad connectors according to the host equipment's port labeling and ensure proper fiber polarity. Monitor link status via the host device management interface and verify 100G link negotiation. For initial deployment, check that connected equipment supports 100G LR4 optics and has matching optical budgets.

Recommendations

Use clean single-mode fiber and LC connectors to maintain signal quality. Verify optical power budget and link loss for the intended fiber path, and perform testing with appropriate optical test equipment after installation. Replace or reseat the module if the host reports faults, and avoid touching the optical interfaces when the fiber is connected.
