Ricetrasmettitore QSFP28 BlueOptics QSFP28-100G-SR4-VA 100G 850nm

The BlueOptics QSFP28-100G-SR4-VA 100G 850nm is a fiber optic transceiver module engineered for short-reach, high-bandwidth links in modern network environments. Designed with a QSFP28 interface, this module supports 100 Gbit/s aggregated data rates and operates at an 850 nm wavelength, making it suitable for multimode fiber connections within data centres and high-performance computing racks. The compact QSFP28 form factor allows for dense port counts and hot-pluggable installation in compatible switches and network equipment.

Advantages

This transceiver provides 100G aggregate throughput over multimode fiber using an industry-standard QSFP28 connector, enabling scalable uplinks and server interconnects. Its 850 nm operation is optimised for short-range links, reducing latency and preserving signal integrity across typical data centre distances. The module’s compact, hot-pluggable design simplifies maintenance and deployment, while adherence to standard electrical and optical interfaces ensures wide compatibility with QSFP28-capable network devices.

Suitable for

• Short-range 100G links within data centre racks and between adjacent racks
• High-performance computing clusters requiring high-bandwidth server interconnects
• Aggregation and spine-leaf network topologies in enterprise and carrier environments
• Upgrading switch uplinks to 100G where multimode fiber is already deployed

Key specifications

• Interface type: QSFP28
• Maximum data transfer rate: 100 000 Mbit/s (100 Gbit/s aggregated)
• Wavelength: 850 nm
• Application range: Short-reach multimode fiber links
• Form factor: QSFP28, hot-pluggable

How to use

Install the QSFP28 module into a compatible QSFP28 port on a switch, router or server NIC while the host device is powered according to the vendor’s service instructions. Connect appropriate multimode fiber cables and verify link status using the network device management interface. Ensure that link settings and transceiver modes on both ends match for 100G operation. Follow standard electrostatic discharge (ESD) precautions when handling the module and cover the optical interfaces with dust caps until the cable is connected.

Recommendations

Use OM3/OM4 multimode fiber for best short-range performance and verify channel loss budget against link distance. Keep firmware and network device drivers up to date and consult equipment compatibility lists to confirm support for QSFP28 100G SR4 modules.
