Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G, QSFP28 SR4 multimode

The Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G, QSFP28 SR4 multimode is a hot-pluggable 100 Gigabit Ethernet optical module designed for short-reach, high-density network links. It implements 4-lane parallel multimode transmission suitable for QSFP28 ports in data center switches, server uplinks and aggregation equipment. The module supports SR4 operation over multimode fiber, enabling compact and energy-efficient 100G connections where cable plant and transceiver density are priorities.

Advantages

This QSFP28 SR4 transceiver delivers four parallel optical lanes for reliable short-range 100G Ethernet with a small form factor compatible with existing QSFP28 interfaces. Its hot-pluggable design allows insertion and removal without powering down equipment, simplifying upgrades and maintenance. The module is optimized for data center environments, providing low power consumption and compatibility with standard multimode fiber cabling commonly used for short-range links.

Suitable for

• Top-of-rack and leaf-spine switch interconnects in data centers
• Server uplinks requiring 100G multimode connections
• Aggregation and distribution links in short-reach network segments
• Environments needing high-density QSFP28 port utilization

Key specifications

• Interface: QSFP28 form factor supporting 100G Ethernet
• Optical technology: 4‑lane parallel multimode (SR4)
• Reach: short-range multimode operation (designed for OM3/OM4 compatible links)
• Connector type: MPO/MTP multi-fiber connector (parallel multimode)
• Power consumption: low-power design suitable for high-density deployments
• Hot-pluggable: supports insertion and removal without system shutdown

How to use

Install the QSFP28 SR4 transceiver into a compatible QSFP28 port on a switch, router or network adapter until it latches. Connect appropriate multimode MPO/MTP fiber cabling aligned to the module’s parallel lanes, observing fiber polarity and connector orientation. After insertion and cabling, verify link status on the host device and configure network settings as required. For removal, disengage any latch mechanism and carefully extract the module. Protect fiber ends with dust caps when not in use.

Recommendations

Use this transceiver with certified OM3 or OM4 multimode fiber infrastructure and MPO/MTP trunk assemblies to achieve the specified short-range 100G performance. Verify compatibility with the host device firmware and QSFP28 port specifications before deployment. Maintain clean fiber connectors and follow ESD precautions during handling to ensure optimal link quality and module longevity.
