## Summary description

CBO QSFP28-100G-SR4 is a fiber optic QSFP28 transceiver module supporting 100G SR4 transmission. Designed for short-reach multimode links, it fits QSFP28 ports to provide four-lane 25G parallel optics. Typical use cases include data center interconnects and high-speed network uplinks where compact, hot-pluggable 100G connectivity is required.

## Long description

The Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G SR4 is a hot-pluggable QSFP28 optical module designed for short-reach multimode fiber links. It delivers 100 Gbit/s aggregate bandwidth using four 25 Gbit/s parallel lanes and is intended for use in data center interconnects, spine-leaf fabrics and high-speed uplink ports. The module fits standard QSFP28 ports and supports compact, high-density 100G connectivity in environments where multimode OM3/OM4 cabling is deployed.
Advantages
The module provides four-lane 25G parallel optics in a QSFP28 form factor, enabling high-density 100G links with hot-pluggable convenience. Its design for short-reach multimode fiber supports lower cost cabling options in data center environments while maintaining industry-standard interfacing. The compact form factor reduces rack space per port and simplifies upgrades from 10G/40G to 100G where compatible QSFP28 ports are available.
Suitable for
 Data center server-to-switch or switch-to-switch interconnects over multimode fiber
 High-speed uplink ports in aggregation and core switches
 Environments using OM3 or OM4 multimode fiber for short-reach links
Key specifications
 Form factor: QSFP28
 Data rate: 100 Gbit/s aggregate (4 × 25 Gbit/s lanes)
 Optical interface: parallel multimode (SR4)
 Reach: short-reach multimode links (typical OM3/OM4 distances)
 Wavelength: parallel lanes optimized for multimode transmission
 Hot-pluggable: yes
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or host adapter while the device is powered according to the equipment manufacturer's instructions. Connect the multimode parallel fiber assembly (compatible MPO/MTP trunk or harness) to the transceiver's optical interface, ensuring correct polarity and secure termination. Verify link status and negotiate speed via the network device's management interface. Follow standard electrostatic discharge (ESD) precautions during handling and avoid touching optical interfaces.
Использование и рекомендации
If used in data center cabling, verify fiber type (OM3/OM4) and channel loss budget to ensure reliable 100G SR4 operation. Replace dust caps only when the transceiver is not in operation and clean connectors per recommended fiber handling procedures.
