Description

The Arista QSFP-100G-LR4 is a QSFP28 optical transceiver delivering 100GbE over duplex single-mode fibre at distances up to 10km, making it an ideal solution for data centre interconnect, campus backbone, metro, and service provider deployments. Operating across four LAN WDM wavelengths (1295–1309nm) via an LC duplex connector, it delivers 103.1 Gb/s aggregate throughput using a 4 x 25.78 Gbps lane architecture. Compliance with IEEE 802.3ba 100GBASE-LR4 and QSFP28 MSA standards ensures broad interoperability with Arista 100G QSFP ports.

Built-in Digital Optical Monitoring (DOM) provides real-time visibility into optical power levels, temperature, bias current, and supply voltage — critical for proactive fault management in enterprise and carrier-grade networks. The hot-swappable design minimises downtime during maintenance, while FEC-enabled Arista switches can extend reach beyond the standard 10km limit. Power consumption is rated at ≤ 4.5W, and the module is RoHS compliant. Visit iptrading.com.au to secure your order — enterprise-grade hardware with expert support.

FAQs

Q: What fibre type and cable distance does the QSFP-100G-LR4 support?
A: The QSFP-100G-LR4 operates over duplex single-mode fibre (SMF) with an LC duplex connector and supports link distances of up to 10km. When used with FEC-enabled Arista switches, reach can be extended beyond the standard 10km limit.

Q: Which Arista switches are compatible with the QSFP-100G-LR4 transceiver?
A: This transceiver is compatible with any Arista switch or router equipped with a 100G QSFP28 port, including the Arista 7050, 7060, 7160, 7280, and 7500 series platforms. Always verify port compatibility against the specific switch datasheet.

Q: Does the QSFP-100G-LR4 support Digital Optical Monitoring (DOM)?
A: Yes. DOM is fully supported via the I2C interface, providing real-time diagnostics including transmit and receive optical power levels, module temperature, laser bias current, and supply voltage — enabling proactive network monitoring and fault isolation.

Q: Is the QSFP-100G-LR4 compliant with industry standards?
A: Yes. The module complies with IEEE 802.3ba 100GBASE-LR4, the QSFP28 MSA (SFF-8665 / SFF-8636), and RoHS environmental directives, ensuring interoperability with other standards-compliant 100G LR4 infrastructure.

Q: Can I purchase the Arista QSFP-100G-LR4 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller supplying Arista transceivers and networking equipment to enterprise, government, and service provider customers. Contact the team for volume pricing, availability, and expert pre-sales support.

Q: What is the power consumption of the QSFP-100G-LR4?
A: The QSFP-100G-LR4 consumes a maximum of 4.5W, making it suitable for high-density 100G deployments in switches and routers where thermal management and power budgets are critical considerations.
