Kuitulähetin-vastaanotin CBO QSFP28 BO28L859S1D 100G QSFP441-BO

The Fiber optic transceiver CBO QSFP28 BO28L859S1D 100G QSFP441-BO is a QSFP28 form-factor module designed for 100 Gigabit Ethernet links. It provides a compact, hot-pluggable optical interface for high-bandwidth network equipment and data center interconnects. The module supports multi-lane operation to deliver aggregate 100G throughput and is suitable for upgrading switches, routers and servers to higher-speed optical links when paired with compatible fiber cabling and optics.

Advantages

This QSFP28 transceiver offers a standardized QSFP28 footprint that simplifies installation in compatible ports and enables hot-swap replacement without interrupting system operation. The module supports high-density deployments thanks to its small form factor and multi-lane 100G capability, allowing efficient use of rack space and port count. Built for interoperability with common 100G Ethernet equipment, it provides reliable optical connectivity for short- and longer-distance links depending on fiber and transceiver subtype used.

Suitable for

• Upgrading data center switches and spine/leaf fabrics to 100G links
• Interconnects between routers and aggregation devices in enterprise networks
• High-performance server uplinks and storage network connections
• Optical trunks for campus and metro network segments (with appropriate fiber)

Key specifications

• Form factor: QSFP28
• Nominal data rate: 100 Gbps aggregate
• Interface type: fiber optic multi-lane QSFP28
• Hot-pluggable design for in-service replacement
• Compatibility: designed for use with 100 Gigabit Ethernet equipment
• Typical application: short- to long-haul optical links depending on fiber and optics chosen

How to use

Install the transceiver into an empty QSFP28 port on a compatible switch, router or server until it seats and the retention latch engages. Connect the appropriate optical fiber cable (compatible with the transceiver subtype and link distance requirements) and verify link status through the network device management interface. For multi-lane operation, ensure connected equipment is configured for 100G operation or for lane breakout if supported. Remove the module by disengaging the retention mechanism and pulling the transceiver straight out while the host port is in a safe state for removal.

Recommendations

Use certified fiber cabling and follow manufacturer guidance for link distance, wavelength and duplex/multi-mode requirements. Confirm compatibility with your network equipment and firmware, and handle the transceiver by the housing to avoid contaminating optical interfaces. Clean connector end-faces before mating and store unused modules with protective caps.
