Description

The Arista QSFP-100G-LRL4 is a 100GBASE-LRL4 QSFP28 optical transceiver delivering 100Gbps connectivity over duplex single-mode fibre (SMF) at reaches up to 2km via a standard Duplex LC connector. Based on the IEEE 802.3 100GBASE-LR4 standard in a shorter-reach variant, it is purpose-built for data centre interconnect, campus backbone, and enterprise core and distribution deployments — anywhere parallel fibre infrastructure is unavailable or impractical.

The module is hot-swappable and MSA-compliant, fitting all Arista 100G QSFP28 ports with no adapter required. With a low 4.0W power draw, Pull Tab latch for tool-free installation, and Digital Optical Monitoring (DOM) for real-time link diagnostics, it simplifies both deployment and ongoing operations. Available now at iptrading.com.au — competitive prices and local support.

Features

FAQs

Q: What is the maximum transmission distance of the QSFP-100G-LRL4?
A: The QSFP-100G-LRL4 supports up to 2km over duplex single-mode fibre (SMF) using a standard Duplex LC connector. This makes it well suited for intra-campus and data centre interconnect links where parallel fibre infrastructure is not available.

Q: How does LRL4 differ from standard LR4?
A: Both LRL4 and LR4 use the same 4-lane LAN-WDM wavelengths (1295nm–1309nm) over single-mode fibre with a Duplex LC interface. The LRL4 variant is optimised for a shorter maximum reach of 2km compared to the 10km reach of full LR4, typically resulting in lower power consumption and cost while meeting most enterprise and campus interconnect requirements.

Q: Which Arista platforms are compatible with the QSFP-100G-LRL4?
A: The QSFP-100G-LRL4 is compatible with all Arista switches and routers equipped with 100G QSFP28 ports, including the 7050X, 7060X, 7260X, 7280R, and 7500R series platforms. Always verify compatibility with your specific platform and EOS version.

Q: Does this transceiver support Digital Optical Monitoring (DOM)?
A: Yes. The QSFP-100G-LRL4 supports DOM, allowing network administrators to monitor real-time optical parameters such as transmit/receive power, temperature, and supply voltage directly from the switch CLI — simplifying troubleshooting and proactive maintenance.

Q: Can I purchase the Arista QSFP-100G-LRL4 in Australia from IP Trading?
A: Yes. IP Trading stocks the Arista QSFP-100G-LRL4 and ships Australia-wide. We offer competitive pricing, local technical support, and fast fulfilment for B2B and enterprise customers. Visit iptrading.com.au or contact our team for volume pricing and availability.

Q: Does the QSFP-100G-LRL4 require any special fibre cabling?
A: No. The module uses a standard Duplex LC connector over conventional duplex single-mode fibre — the same cabling used in most existing enterprise and data centre fibre plants. There is no requirement for specialised parallel (MPO/MTP) fibre infrastructure.
