## Long description

The Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G SR4 by BlueOptics is a QSFP28 form-factor module designed for short-range multimode fiber links. It supports 100 Gbps data rates using four parallel lanes and is intended for use in data centers and network aggregation where high-bandwidth, short-reach connectivity is required. The module is hot-pluggable and fits standard QSFP28 ports to simplify upgrades and scalable deployment of 100G links.
Advantages
This QSFP28 100G SR4 transceiver provides compact, high-density fiber connectivity for short-reach multimode environments. The module’s four-lane parallel architecture allows reliable 100 Gbps throughput while maintaining compatibility with common QSFP28 interfaces. Hot-pluggable design reduces maintenance downtime and enables flexible replacement or scaling. The device is appropriate for deployments that prioritize space efficiency and straightforward integration into existing optical infrastructure.
Suitable for
 Short-range multimode fiber links within data centers
 Aggregation switches and spine-leaf network architectures
 Interconnects between racks and server clusters
 High-density 100G port deployments in networking equipment
Key specifications
 Form factor: QSFP28
 Data rate: 100 Gbps aggregate (four 25 Gbps lanes)
 Optical type: Multimode fiber (SR4)
 Transmission distance: short-range multimode links (designed for campus and data center reaches)
 Connector type: MPO/MTP parallel connector interface
 Installation: Hot-pluggable
 Power consumption: typical for QSFP28 transceiver class (refer to device datasheet for exact values)
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port on a switch or optical device while the host is powered as supported by the hardware. Connect multimode fiber using an MPO/MTP trunk or harness appropriate for SR4 parallel transmission. Ensure the connected end equipment and cabling support 100G SR4 operation and that lane mapping and transceiver settings on the host device match the intended link configuration. Use standard network management tools to verify link status and performance after installation.
Usage recommendations
Use high-quality multimode fiber and MPO/MTP connectors rated for SR4 applications, follow ESD precautions during handling, and validate compatibility with the host device firmware. For reliable operation, maintain proper fiber bend radius, secure connections to prevent loss, and consult the system vendor’s guidance for optical power budget and lane configuration.
