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

The BlueOptics Fiber optic transceiver CBO QSFP28-100G-LR4 100G LR4 module is a QSFP28 form-factor module for single-mode fiber links that supports 100 Gigabit Ethernet LR4 transmission. It is designed to fit QSFP28 ports on switches, routers and data center equipment and to enable long-reach connections over single-mode fiber. The module converts electrical signals to optical LR4 signals and back, allowing reliable high-speed data transport for backbone, aggregation and inter-rack links.

Advantages

This 100G LR4 transceiver provides long-reach single-mode performance with a compact QSFP28 footprint, reducing the number of optical lanes required for high-bandwidth links. It supports interoperable QSFP28 interfaces for straightforward hot-plug installation and replacement, and its LR4 design uses four wavelength channels for single-mode transmission, enabling extended distance links while maintaining 100GbE throughput and low latency.

Suitable for

• Long-reach 100 Gigabit Ethernet backbone connections over single-mode fiber
• Aggregation and inter-rack links in data centers and campus networks
• High-speed uplinks between switches and routers supporting QSFP28

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gbit/s
• Optical type: LR4 (long reach, four-wavelength DWDM-style transmission over SMF)
• Fiber: single-mode fiber compatibility
• Connector type: compatible with standard LC duplex/quad or MPO variants depending on equipment interface (check host port compatibility)
• Use case: designed for long-distance links such as backbone and inter-rack connections

How to use

Install the transceiver into a compatible QSFP28 port on your switch or router while the device is powered on, following the host equipment instructions for hot-plug modules. Connect appropriate single-mode fiber patch cords and ensure transmit and receive fibers are correctly aligned. Verify link status through the host device management interface and monitor optical parameters if supported. For replacement, remove the existing module carefully by releasing the latch and sliding the module out, then insert the new module until it seats and locks.

Recommendations

Confirm that the host equipment supports QSFP28 LR4 transceivers and consult the switch or router compatibility list before installation. Use appropriate single-mode fiber cabling and clean connectors prior to mating. Observe electrostatic discharge (ESD) precautions during handling and avoid bending the fiber beyond recommended bend radii to preserve optical performance.
