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

The BlueOptics Fiber Optic Transceiver CBO QSFP28-100G-LR4 100G LR4 is a QSFP28 form-factor module designed for 100 Gbps LR4 transmission over single-mode fiber. It provides long-reach optical connectivity for switches, routers and dedicated optical equipment in data centers, carrier networks and enterprise backbone links. The module supports standard QSFP28 electrical interfaces and LR4 wavelength division multiplexing to deliver four 25 Gbps lanes aggregated to a single 100 Gbps link, enabling reliable high-speed links over single-mode fibers.

Advantages

This transceiver delivers stable 100 Gbps performance for long-distance single-mode links while maintaining compatibility with QSFP28 ports. Its LR4 design uses coarse wavelength division multiplexing to transport four 25 Gbps channels over a single fiber pair, reducing cabling complexity for uplinks and interconnects. Compact QSFP28 packaging offers straightforward installation and hot-pluggable replacement in standard networking equipment. The module is intended to meet typical temperature and optical budget requirements for carrier and data center environments.

Suitable for

• Data center uplinks and aggregation switches
• Carrier and telecom long-haul links on single-mode fiber
• Enterprise backbone connections between buildings or campuses
• High-capacity interconnects between routers and optical transport equipment

Key specifications

• Form factor: QSFP28 (quad small form-factor pluggable)
• Nominal data rate: 100 Gbps (4 × 25 Gbps lanes)
• Transmission type: LR4 (long reach, four-wavelength multiplexing)
• Fiber type: single-mode fiber (SMF)
• Connector type: duplex LC
• Optical reach: designed for long-reach single-mode links (typical carrier/data center distances)
• Hot-pluggable: yes

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 slot on a switch, router or optical transport device while the host port is powered and supporting 100G QSFP28 modules. Connect the duplex LC single-mode fiber cable between transceiver ports and the remote endpoint, observing proper fiber handling and connector cleanliness. Ensure the host equipment is configured for a 100 Gbps LR4 optical interface and verify link status and optical diagnostics through the device management interface. When replacing modules, remove the transceiver by disengaging the latch and gently pulling it from the port.

Recommendations

To ensure consistent performance, use single-mode LC patch cords with appropriate attenuation and maintain clean connectors. Verify compatibility with the host device's supported transceiver list and confirm optical power budgets for the intended link distance. Monitor transceiver diagnostics for temperature and optical levels during commissioning and routine operation.
