-
100 Gigabit performance with 100GBASE-SR4: Ideal for modern data centres, spine-leaf architectures and high-performance core networks with high data throughput.
-
Up to 100 m range: Optimised for multimode fibres (OM4 up to 100 m, OM3 up to 70 m) – perfect for structured high-speed cabling within racks or data centres.
-
4x25Gb/s at 850 nm (VCSEL array): Four parallel channels, each with 25.78 Gb/s, ensure stable and efficient 100G transmission via an MPO-12 interface.
-
Digital Diagnostic Monitoring (DDM): Precise real-time monitoring of temperature, voltage, TX/RX power and bias current via I²C interface – for maximum transparency during operation.
-
MSA and IEEE compliant: Compatible with QSFP28 MSA, IEEE 802.3bm and SFF-8636 – making it widely usable with commercially available 100G switches and routers.
The InLine® QSFP28-100G-SR4 module provides reliable 100 Gigabit Ethernet connections via multimode fibre. With an aggregate data rate of 100 Gb/s (4x25.78 Gb/s), it is ideal for high-performance applications in data centres, enterprise core networks and high-performance server environments.
Transmission is via an 850 nm VCSEL array with PIN receiver structure. Thanks to parallel 4-channel technology, a range of up to 100 metres on OM4 and 70 metres on OM3 fibres is achieved. Connection is via an MPO-12 interface.
With a power consumption of less than 2.5 W, the module remains energy-efficient despite its high bandwidth. Power is supplied via 3.3 V. The operating temperature range of 0 °C to +70 °C makes the module suitable for typical data centre environments.
Digital Diagnostic Monitoring (DDM) enables continuous monitoring of important operating parameters such as temperature (±3 °C), supply voltage (±3 %) and TX and RX power. This allows network conditions to be detected at an early stage and maintenance measures to be planned in a targeted manner.
The module is hot-pluggable and can be inserted or replaced during operation – a clear advantage for high-availability IT infrastructures.
