Transceiver CBO AT-QSFPLR4 Fiber Optic 100G SFP28 / QSFP28 compatible

The Transceiver CBO AT-QSFPLR4 Fiber Optic 100G SFP28 / QSFP28 compatible from BlueOptics is a fiber-optic module engineered for 100 Gigabit Ethernet links. It provides a compact optical interface compatible with equipment that supports QSFP28 or SFP28 form factors, enabling high-speed data transmission for enterprise and data center networks. The module is intended for creating reliable fiber connections between switches, routers and servers where 100G bandwidth and low-latency performance are required.

Advantages

This BlueOptics transceiver supports 100G transmission rates while maintaining compatibility with common QSFP28 and SFP28-capable ports, offering flexible deployment options across different network devices. The module is built to deliver stable optical signals for long-duration operation and provides consistent throughput for high-bandwidth applications. Compact design and standard electrical/optical interfaces simplify installation and integration into existing network racks and optical links.

Suitable for

• Data center interconnects and spine-leaf architectures
• Core and aggregation switch uplinks requiring 100G capacity
• High-performance server and storage network connections
• Scalable network upgrades where QSFP28/SFP28 compatibility is needed

Key specifications

• Nominal data rate: 100 Gigabit Ethernet
• Form-factor compatibility: QSFP28 and SFP28 compatible physical interface
• Connector type: fiber-optic duplex interface (LC-compatible or QSFP28 optical mating depending on host port)
• Optical medium: single-mode fiber (typical for 100G long-reach deployments)
• Operating environment: designed for standard telecom and data center ambient conditions

How to use

Install the transceiver into a compatible QSFP28 or SFP28 slot on your network device following the host vendor’s guidelines for hot-swap modules. Ensure the module is fully seated and the latch or ejector is secured, then connect the appropriate single-mode fiber patch cable between devices. Verify link status and transceiver recognition through the switch or router management interface, and configure network ports for 100G operation as required by your topology and VLAN/settings policies.

Usage recommendations

For reliable operation, use high-quality single-mode fiber and LC (or manufacturer-recommended) connectors, maintain proper fiber cleanliness, and follow ESD-safe handling procedures when inserting or removing the module. Confirm compatibility with the host device’s transceiver support list and monitor optical power and link statistics during deployment to ensure expected performance.
