## Summary description

The Digitus 100Gbs QSFP28 SR4 Optical Transceiver supports a maximum data transfer rate of 100000 Mbit/s. It is designed for high-speed fiber optic connections and is compatible with various brands. The transceiver operates at an input voltage of 3.3 V and has a typical power consumption of 3.5 W. Its compact dimensions make it suitable for various networking applications.

## Long description

The Digitus DN-81630 is a four-channel, hot-pluggable QSFP28 optical transceiver designed for parallel multimode fiber links. It supports four independent full‑duplex channels, each rated up to 26 Gbit/s for an aggregate throughput of up to 104 Gbit/s (commonly used for 100GBASE-SR4). The module uses an 850 nm VCSEL laser array, accepts MPO/MT-RJ style ribbon fiber connectors and is intended for short‑reach multimode fiber networks (OM3/OM4). It is powered from a 3.3 V supply, consumes less than 3.5 W, and operates in an ambient case temperature range of 0 °C to +70 °C. The transceiver conforms to RoHS 6 and provides integrated digital diagnostic monitoring.
Advantages
The QSFP28 SR4 form factor offers high port density and lower system cost per bit by providing four parallel 26 Gbit/s lanes in a single, hot‑pluggable module. Low power consumption (\<3.5 W) and a compact nickel-coloured package reduce thermal and space impact in data centers. Integrated digital diagnostic functions enable real-time monitoring of optical and electrical parameters.
Suitable for
100GBASE‑SR4 connections over multimode fiber (OM3/OM4)
40 Gigabit Ethernet or InfiniBand FDR/EDR deployments using parallel optical links
High‑density switch and server uplinks where port density and low power are required
Short‑reach data center fabric and aggregation links up to 70 m on OM3 and 100 m on OM4

How to use
Install the QSFP28 module into a compatible QSFP28 receptacle on a switch, router or host adapter while the host is powered or according to the equipment manufacturer’s hot‑plug guidance. Connect an MPO/MT‑style multimode fiber ribbon cable to the module’s receptacle, observing correct polarity and cable routing. Verify link status and monitor module diagnostics through the host device’s management interface to ensure proper operation and optical budget compliance.
Usage recommendations
Use OM3 or OM4 multimode fiber with appropriate MPO/MT connectors and ensure end-to-end multimode channel verification. Maintain proper cable bend radius and follow ESD handling precautions when inserting or removing the QSFP28 SR4 transceiver. For maximum reach, choose OM4 fiber and confirm transceiver and host firmware compatibility.
