QSFP28 Transceiver BlueOptics BO28L859S1D 100G 850nm 100000 Mbit/s

The BlueOptics QSFP28 BO28L859S1D is a high-speed fiber optic transceiver module designed for short-reach 100 Gbit/s links. It implements the QSFP28 interface and uses an 850 nm multimode optical wavelength to support aggregated data transfer up to 100000 Mbit/s. With a compact QSFP28 form factor and silver housing, the module is suitable for installation in modern network switches, routers and servers in data center and high-performance computing environments where reliable 100G connectivity is required.

Advantages

This QSFP28 transceiver delivers a standardized 100G physical interface with compatibility for common multimode fiber infrastructures. The module provides high-density port options thanks to the compact QSFP28 form factor and supports low-latency, high-throughput links. Its 850 nm optical wavelength is widely used for short-range multimode connections and allows straightforward integration into existing fiber runs without the need for protocol-specific changes.

Suitable for

• Short-reach 100G links in data centers
• Interconnects between switches and aggregation devices
• High-performance computing clusters requiring 100G bandwidth
• Switch and server uplinks over multimode fiber

How to use

Install the BlueOptics QSFP28 module into a compatible QSFP28 port on a switch, router or server following the host device manufacturer’s hot-plug guidelines. Connect the module to a matching multimode fiber patch cable terminated for 850 nm operation and ensure correct polarity and connector type. After insertion, verify link status and data rate on the host device and configure the network interface as required by your environment. Follow standard ESD precautions while handling the transceiver and keep protective caps on the fiber interfaces until cabling is complete.

Usage recommendations

Use the module with multimode fiber rated for 850 nm short-reach connections and within the supported link distances for 100G SR applications. Confirm compatibility with your switch or server vendor and firmware when deploying in production networks. Store and handle the transceiver in a clean, dry environment and avoid exposing optical interfaces to dust or physical damage.
