Network transceiver module CBO BO28L859S1D QSFP28 100000 Mbit/s (optical)

CBO BO28L859S1D is a QSFP28 network transceiver module designed for 100000 Mbit/s optical links. The module provides a compact, hot-pluggable form factor for integration into QSFP28 ports on switches, routers and servers. Intended for high-density data center and enterprise network environments, this optical transceiver enables 100 Gb/s connections over compatible fiber infrastructure and supports typical use cases such as server uplinks, switch interconnects and aggregation paths.

Advantages

The transceiver offers a QSFP28 form factor that supports high port density and efficient rack-space utilization. Hot-pluggable design allows replacement or upgrade without powering down equipment, minimising maintenance downtime. The optical interface provides low-latency, high-throughput connectivity suitable for backbone links and uplinks. Built to industry form-factor standards, the module is interoperable with equipment that accepts QSFP28 optical modules.

Suitable for

• 100 Gb/s server uplinks in data centers
• Switch-to-switch optical interconnects and spine-leaf architectures
• Aggregation links between distribution and core switches
• High-bandwidth point-to-point optical connections

Key specifications

• Interface: QSFP28 optical transceiver form factor
• Data rate: 100000 Mbit/s (100 Gb/s)
• Media type: optical fiber link
• Hot-pluggable: yes
• Typical applications: server uplinks, switch interconnects, aggregation

How to use

Install the module into a compatible QSFP28 port following the host device manufacturer’s mechanical insertion procedure. Connect appropriate single-mode or multimode fiber patch cords according to the supported fiber type and link budget of your network. Verify link status through the host device management interface and ensure transceiver settings match the network topology and speed requirements. Replace or remove the module only when the host allows hot-swap or during scheduled maintenance to avoid disrupting active links.

Recommendations

For reliable operation, use fiber patch cords and duplex/parallel cabling that meet the transceiver’s optical requirements and maintain controlled bend radius and clean connectors. Confirm compatibility with the host equipment’s QSFP28 port and firmware, and perform link tests after installation to validate signal integrity and throughput.
