## Summary description

BlueOptics QSFP28 fiber assembly BO282803L7M is a 100G 850 nm multimode optical transceiver designed for high-speed short-reach data links. Compatible with QSFP28 ports, it supports 100 Gigabit Ethernet over multimode fiber (typ. OM3/OM4) for data centers, switches and servers. Provides plug-and-play connectivity for aggregated links, low-latency transmission and straightforward deployment in rack environments.

## Long description

BlueOptics QSFP28 fiber assembly BO282803L7M is a 100G multimode optical transceiver operating at 850 nm and designed for short-reach, high-bandwidth connections. The module fits QSFP28 ports and provides plug-and-play connectivity for 100 Gigabit Ethernet links over multimode fiber typically used in OM3 and OM4 cabling infrastructures. It is suitable for installation in data center switches, aggregation devices and server network interfaces where low-latency, high-throughput links are required.
Advantages
The transceiver delivers 100G data rate over multimode fiber with low latency and straightforward integration into existing QSFP28-capable hardware. Its 850 nm optics are optimized for short-range multimode links and are compatible with OM3 and OM4 fiber standards, enabling high-density aggregation and linking in rack environments. The plug-and-play form factor reduces deployment time and simplifies replacement or scaling of optical connections.
Suitable for
100 Gigabit Ethernet links between switches and core aggregation points in data centers
High-throughput server interconnects and top-of-rack uplinks
Short-reach multimode fiber runs using OM3 or OM4 cabling
Key specifications
Form factor: QSFP28 multimode optical transceiver
Data rate: 100 Gigabit Ethernet
Wavelength: 850 nm
Fiber type: multimode fiber; compatible with OM3 and OM4
Reach: short-reach multimode links (data center/aggregation distances)
Connectivity: hot-pluggable QSFP28 interface for 100G ports
How to use
Install the transceiver into a compatible QSFP28 port until it seats firmly; handle the module by its housing and avoid touching the optical interface. Use compatible multimode fiber patch cords (OM3 or OM4) with appropriate LC or MPO/MTP connectors depending on the assembly. After insertion, allow the host device to recognize the module; verify link status and correct port configuration on the switch or server. For replacement, power down the port if recommended by the hardware vendor, remove the module by the housing, cover the optical interface when not in use and insert the new module following the same steps.
Usage recommendations
Maintain clean fiber endfaces and use dust caps when modules are not connected. Use OM3 or OM4 multimode patch cords of appropriate length to minimize bend loss and avoid exceeding recommended link distance for 850 nm short-reach optics. Verify compatibility with the host equipment vendor’s supported transceiver list when deploying at scale.
