BlueOptics Q28-100G-ESR4-BO network transceiver module Fiber optic 40000 Mbit/s QSFP

The BlueOptics Q28-100G-ESR4-BO is a QSFP fiber optic transceiver module designed for high-speed multimode optical links with a maximum data transfer rate of 40000 Mbit/s. Housed in a compact silver QSFP form factor and weighing approximately 0.04 kg, the module implements 100GBASE-ESR4 signaling with MPO/MTP connectivity and supports simultaneous transmit and receive operation on 850 nm optical channels. It follows MSA-compliant QSFP/QSFP28 mechanical and electrical interfaces for use in compatible network hardware.

Advantages

The transceiver provides a standardized QSFP interface that enables straightforward integration into switches, routers and storage systems that accept QSFP/QSFP28 modules. Built and tested to meet MSA specifications, the module uses industry-grade optical and electronic components to ensure compatibility, predictable behavior and extended service life. Integrated digital diagnostics (DDM/DOM, SFF-8472 compliant) supports real-time monitoring of parameters such as supply voltage, optical power and temperature to simplify troubleshooting and maintenance.

How to use

Install the BlueOptics Q28-100G-ESR4-BO by inserting the QSFP module into a compatible QSFP/QSFP28 cage on a switch, router or other network device following the vendor's hot-swap procedure. Connect an MPO/MTP multimode patch or trunk cable to the module's MPO/MTP receptacle, ensuring correct fiber polarity and that the cable and patch panels are rated for 100GBASE-ESR4 multimode operation. Configure the host device port as required for 100G operation and verify link status. If available and supported by the host, use the DDM/DOM interface to read real-time module parameters for diagnostics and monitoring.

Recommendations

Use high-quality multimode MPO/MTP fiber assemblies and ensure proper cable management to maintain signal integrity. Verify host device compatibility with 100GBASE-ESR4 MPO/MTP QSFP modules and enable DDM/DOM support on the host to leverage remote diagnostics. Follow manufacturer guidelines for insertion/removal and observe electrostatic discharge (ESD) precautions when handling the transceiver.
