BlueOptics JNP-QSFP-100G-SR4-BO network transceiver module 40000 Mbit/s QSFP28 850 nm

The BlueOptics JNP-QSFP-100G-SR4-BO is a QSFP28 fiber optic transceiver module designed for high-speed short-reach links. It supports a maximum data rate of 40000 Mbit/s and operates at an 850 nm wavelength over multimode fiber using an MPO/MTP connector. The compact metal housing and a weight of approximately 40 g make the module suitable for installation in compatible QSFP28 ports on switches, routers and storage systems. The module is RoHS, CE and FCC compliant and implements MSA-defined electrical and mechanical interfaces for interoperability with devices that accept Juniper-compatible 100GBASE-SR4 QSFP28 modules.

Advantages

This QSFP28 transceiver provides a standardized 100GBASE-SR4 short-reach interface that enables simultaneous transmit and receive over multimode fiber. Digital diagnostic monitoring (DDM/DOM) is available for real-time monitoring of supply voltage, laser bias current, optical transmit and receive power and temperature when supported by host hardware. The product follows MSA specifications for QSFP28, ensuring electrical and mechanical compatibility with a wide range of network equipment. Compliance with CE, RoHS and FCC standards confirms regulatory conformity for professional network deployments.

Suitable for

• Short-reach 100G Ethernet links in data centers (up to ~100 m on multimode fiber)
• High-speed interconnects between switches and routers
• Fiber uplinks for storage systems and aggregation switches
• Environments requiring digital diagnostics (DDM/DOM) for optical link monitoring

How to use

Install the BlueOptics QSFP28 module into an empty QSFP28 port on supported network equipment, ensuring the module is fully seated and latched. Connect an MPO/MTP multimode fiber patch cord between the transceiver and the corresponding remote transceiver or patch panel, observing correct polarity and fiber type. If the host platform supports digital diagnostics, monitor DDM/DOM parameters through the device management interface to verify optical power and temperature. Follow the equipment vendor’s guidelines for hot-plugging and firmware compatibility when installing third-party transceivers.

Recommendations

Use high-quality OM3/OM4 multimode fiber and MPO/MTP patch cords to achieve expected short-reach performance. Verify that the target hardware supports Juniper-compatible QSFP28 modules and enable DDM/DOM monitoring if remote diagnostics are required. For troubleshooting, check optical power levels and module temperature via diagnostics and ensure firmware on host devices is up to date.
