## Summary description

BlueOptics UACC-OM-QSFP28-SR4 is a QSFP28 optical transceiver for 100G Ethernet links using OM4 multimode fiber at 850 nm. Designed for short-reach connections, it supports QSFP28 interfaces and SR4 parallel optics for high-density data center and core switching applications. Practical for upgrading network ports to 100G and enabling multi-lane short-distance transmission.

## Long description

BlueOptics UACC-OM-QSFP28-SR4 100G OM4 850nm is a QSFP28 optical transceiver module engineered for 100 Gigabit Ethernet short-reach links over OM4 multimode fiber at a wavelength of 850 nm. The module implements SR4 parallel optics and a QSFP28 electrical interface to deliver four lanes of 25 Gbps each, providing a compact solution for high-density data center switching and aggregation. It is suitable for replacing or upgrading compatible QSFP28 ports to support 100G connectivity in short-distance network installations.
Advantages
The transceiver supports multimode OM4 fiber, enabling increased reach and higher modal bandwidth compared with lower-grade multimode types, which helps maintain signal integrity for short-reach 100G links. Its QSFP28 form factor and SR4 parallel optic design reduce port density and cabling complexity in rack environments, while offering compatibility with standard 100G Ethernet interfaces. The module is intended for straightforward hot-pluggable integration into QSFP28-capable equipment, facilitating upgrades without extensive hardware changes.
Suitable for
Data center spine and leaf switching where short-reach 100G links are required
Server and storage aggregation within the same or adjacent equipment racks
High-density switch-to-switch connections in core network segments
Upgrading existing multimode fiber infrastructure to 100 Gigabit capacity
Key specifications
Form factor: QSFP28
Application: 100 Gigabit Ethernet
Fiber type: OM4 multimode fiber
Wavelength: 850 nm
Optical architecture: SR4 parallel optics (4 lanes × 25 Gbps)
Reach: short-reach links over OM4 (optimized for data center distances)
Hot-pluggable design for in-service installation
How to use
Install the transceiver into a compatible QSFP28 port on network equipment while the port supports hot-plug operation. Connect the module to OM4 multimode fiber using appropriate MPO/MTP parallel trunk cables terminated to match the SR4 lane alignment. Verify link status and speed through the switch or host interface management to ensure the 100G link is established. Follow vendor guidance for optical budget and cable polarity to maintain proper signal mapping across lanes.
Usage recommendations
Use OM4-rated MPO/MTP cabling and maintain clean connector end-faces to ensure optimal signal performance. Confirm compatibility with your switch or transceiver partner list and observe recommended fiber channel layouts for SR4 parallel optics to avoid lane misalignment. For best results in data center environments, keep cable runs within the recommended short-reach distances for OM4.
