## Long description

The BlueOptics 100G-QSFP28-SR4-EN-BO is a QSFP28 multimode fiber transceiver designed for 100GBASE-SR4 applications in data centers and high-density network environments. It supports an aggregate data rate of 100000 Mbit/s over parallel multimode fiber using an MPO/MTP connector and operates at an 850 nm wavelength. The module is compact and lightweight (approximately 40 g), conforms to QSFP28 MSA mechanical and electrical specifications, and provides hot-pluggable 100 Gigabit Ethernet connectivity for switches, routers and optical aggregation equipment that accept QSFP28 SR4 optics.
Advantages
The transceiver delivers standardized QSFP28 connectivity compatible with equipment that supports 100GBASE-SR4, enabling high-bandwidth links up to typical multimode distances. Built to MSA guidelines, it supports digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmitted power, received power and temperature. Using MPO/MTP connectivity and proven optical components, the module offers predictable performance, low electromagnetic susceptibility inherent to fiber optics, and a small form factor suitable for high-density racks.
Suitable for
 100 Gigabit Ethernet trunk links in data centers
 Switch-to-switch connections in campus and enterprise networks
 High-speed interconnects between servers, storage arrays and aggregation devices
 Short-reach multimode fiber links (up to typical OM3/OM4 distances for SR4)
Key specifications
 Interface type: QSFP28 (MPO/MTP connector)
 Data rate: 100000 Mbit/s aggregate (100G)
 Wavelength: 850 nm (transmit and receive)
 Fiber type: Multimode fiber, 4-lane parallel optics (SR4)
 Form factor: QSFP28, hot-pluggable
 Weight: approximately 0.04 kg
 Digital diagnostics: DDM/DOM support (MSA SFF-8472 compatible)
How to use
Install the QSFP28 module into a compatible QSFP28 port until the module seats securely and the retention latch engages. Connect an MPO/MTP multimode patch cable to the transceiver, ensuring correct polarity and matching fiber type (OM3/OM4 as applicable). Verify that the host device recognizes the module and, if required, enable or confirm DDM/DOM monitoring in the network equipment management interface to access diagnostics data. For safe hot-plugging, follow the host vendor’s guidelines for insertion and removal and ensure electrostatic discharge precautions during handling.
Usage recommendations
Use certified multimode MPO/MTP patch cords and appropriate breakouts or patch panels to preserve signal integrity. Match the cabling grade (OM3/OM4) and maintain correct polarity when connecting SR4 lanes. Verify that the network hardware supports 100GBASE-SR4 QSFP28 modules and DDM/DOM features for monitoring. For optimal link performance, minimize bends and stress on fiber runs and perform link testing after installation.
