Description

The Arista QSFP-100G-SR4 is a 100GBASE-SR4 QSFP28 optical transceiver designed for high-density 100G deployments across data centre top-of-rack, campus core, and enterprise distribution environments. Operating at 850nm over parallel multimode fibre with an MPO-12 UPC connector, it delivers reliable 100Gbps connectivity at up to 70m on OM3 or 100m on OM4 MMF. Support for 4x25G breakout mode adds deployment flexibility, while Digital Optical Monitoring (DOM) enables real-time visibility into transceiver health.

Compliant with IEEE 802.3bm 100GBASE-SR4 and the QSFP28 MSA (SFF-8665), this hot-pluggable module integrates directly with all Arista 100G QSFP switch ports. An E-Series variant (QSFP-100G-SR4-E) is also available for enhanced low-latency applications without FEC requirements. Order now at iptrading.com.au — trusted by Australian IT professionals.

FAQs

Q: What fibre type and maximum distance does the QSFP-100G-SR4 support?
A: The Arista QSFP-100G-SR4 operates over parallel multimode fibre (MMF) using an MPO-12 UPC connector, reaching up to 70m on OM3 and up to 100m on OM4 fibre at 850nm.

Q: Can the QSFP-100G-SR4 be used in breakout configurations?
A: Yes. The module supports 4x25G breakout mode via a CAUI-4 electrical interface, allowing a single 100G port to connect to four individual 25G ports using an MPO-12 to 4x LC breakout cable.

Q: Is the QSFP-100G-SR4 compatible with non-Arista switches?
A: The module is fully compliant with the IEEE 802.3bm 100GBASE-SR4 standard and QSFP28 MSA (SFF-8665), ensuring optical interoperability with any standards-compliant 100G QSFP28 device from other vendors.

Q: What is the difference between QSFP-100G-SR4 and QSFP-100G-SR4-E?
A: The E-Series (QSFP-100G-SR4-E) is an enhanced variant designed for low-latency applications that do not require Forward Error Correction (FEC), making it well-suited for latency-sensitive workloads in data centre environments.

Q: Does the QSFP-100G-SR4 support Digital Optical Monitoring?
A: Yes. The module includes Digital Optical Monitoring (DOM), enabling real-time reporting of TX/RX optical power levels, temperature, supply voltage, and bias current through the management interface.

Q: Can I purchase the Arista QSFP-100G-SR4 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) stocks Arista optic modules and supplies Australian businesses, including enterprise IT teams and data centre operators. Order online or contact the team for volume pricing and availability.
