FAQ About 100G QSFP28 SR4 Optical Transceiver
The Fibrecross 100G QSFP28 SR4 module offers 100Gbps data rate, 850nm wavelength, up to 100m reach over OM4 fiber, MTP/MPO connector, and supports Digital Optical Monitoring (DOM).
A 100G QSFP28 SR4 data center interconnect solution uses a QSFP28 SR4 hot-pluggable module to create a high-bandwidth, low-latency link between racks or rooms in the data center. It leverages four parallel 25 Gbps lanes over OM4 multimode fiber to reach up to 100 m, fully compliant with IEEE 802.3bm 100GBASE-SR4 standards.
To achieve QSFP28 SR4 top-of-rack switch connectivity, install the QSFP28 SR4 module in the TOR switch uplink port and connect it via an MTP/MPO-12 multimode fiber cable. Servers connect to the TOR switch via SFP+ or SFP28 links, while the SR4 module aggregates traffic upstream, simplifying cabling and improving density.
Yes—100G QSFP28 SR4 DOM monitoring support is built-in. The module provides Digital Diagnostics Monitoring (DOM) via an I²C interface, allowing real-time visibility into transmit bias current, receive optical power, temperature, and supply voltage for proactive maintenance.
All standard QSFP28 SR4 modules are hot-pluggable 100G QSFP28 SR4 module devices. They can be inserted or removed without powering down the switch, minimizing downtime. These modules comply with the QSFP28 MSA and IEEE 802.3bm for broad interoperability.
Fibrecross is a leading optical transceiver manufacturer in China, provides QSFP28 SR4 transceivers with DDM support and global shipping.
