## Summary description

The BlueOptics N-QSFP28-LR4-BO is a fiber optic network transceiver module designed for high-speed data transfer up to 100000 Mbit/s. It features a QSFP28 interface, metal housing, and a lightweight design at 40 g. Ideal for data centers and high-performance networking applications.

## Long description

The BlueOptics N-QSFP28-LR4-BO network transceiver module is a QSFP28 fiber optic module designed for high-speed data transmission up to 100000 Mbit/s. Housed in a metal enclosure and weighing approximately 40 g, this silver-coloured transceiver supports single-mode fiber links with LC duplex connectivity and follows common MSA form-factor conventions for QSFP28 modules.
Advantages
The module provides 100G-class data rates through a QSFP28 interface and is built in a compact metal housing to support rack-mounted networking equipment. Its lightweight construction and standard form factor make integration into switches, routers and other networking hardware straightforward. The design supports long-reach fiber transmission typical for LR4 optics and includes diagnostic capabilities when used with compatible host hardware.
Suitable for
Core and aggregation links in data centers
High-performance networking between switches and routers
Long-reach single-mode fiber connections for storage and compute clusters
Replacement or upgrade of QSFP28 LR4 ports in compatible equipment
Key specifications
Interface type: QSFP28
Maximum data transfer rate: 100000 Mbit/s (100 Gbit/s)
Connector: LC duplex (single-mode fiber)
Housing: metal
Weight: 0.04 kg
Product colour: Silver
How to use
Install the transceiver into a compatible QSFP28 port on your network device following the equipment manufacturer’s hot-plug procedures. Connect an appropriate single-mode LC duplex patch cable to the module and the remote device. If your hardware supports Digital Diagnostics Monitoring (DDM/DOM), enable and query the diagnostics via the host interface to monitor supply voltage, laser bias current, optical output and input power, and temperature in real time. Ensure firmware and software on the host device support third-party QSFP28 modules where required.
Usage recommendations
Use single-mode LC duplex fiber and verify compatibility with the host platform for LR4 optics. Keep firmware updated on the host device and handle the module by its edges to avoid contamination of optical interfaces. Store and operate the transceiver within the manufacturer-recommended environmental ranges and use protective dust caps on unused connectors.
