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

The Transceiver CBO QSFP28-100G-SR4 Fiber Optic 100G by BlueOptics is a short-reach QSFP28 module designed for 100G Ethernet links over multimode fiber. It aggregates four 25G lanes into a single QSFP28 form factor, providing high-density connectivity for switches, routers and data center equipment. The module is suitable for short-distance multimode fiber connections and fits QSFP28 ports for straightforward installation and network upgrades.

Advantages

This QSFP28 transceiver supports 100G data rates with four independent 25G lanes, enabling efficient bandwidth aggregation in a compact form factor. Its compatibility with standard multimode fiber systems simplifies deployment in existing infrastructures. The module’s plug-in QSFP28 design allows quick installation and replacement without special tools, while maintaining signal integrity for short-reach links in enterprise and data center environments.

Suitable for

• 100G Ethernet connections in data center top-of-rack and leaf-spine architectures
• Short-reach multimode fiber links between switches and routers
• High-density aggregation ports where QSFP28 form factor is required
• Upgrades from lower-speed transceivers to 100G-capable hardware

Key specifications

• Form factor: QSFP28 (quad 25G lanes)
• Data rate: 100 Gbps aggregate
• Media type: Multimode fiber (short-reach SR4)
• Optical interface: MPO/MTP connector for 4-channel parallel optics
• Typical reach: optimized for short distances on multimode fiber
• Application: 100G Ethernet networking

How to use

Install the transceiver by inserting the QSFP28 module into a compatible QSFP28 port on a switch or router until it latches. Connect the multimode MPO/MTP fiber trunk cable to the module’s optical interface, ensuring correct polarity and channel mapping. Verify link status and speed on the host device and monitor port diagnostics if supported. For removal, disengage the latch and pull the module straight out to avoid damaging the host port.

Recommendations

Use multimode fiber certified for short-reach 100G applications and maintain clean connector endfaces to ensure optimal performance. Match fiber type and cable structure to the module’s SR4 specification, and follow equipment vendor guidance for interoperability and firmware compatibility checks.
