Arista QSFP-100G-LRL4-Arista | 100G QSFP28 Transceiver, Single-Mode, 2km, LC

Q: What is the difference between QSFP-100G-LRL4 and QSFP-100G-LR4?
A: The QSFP-100G-LRL4 is optimized for medium-reach applications up to 2km, while the QSFP-100G-LR4 supports longer distances up to 10km. The LRL4 variant offers a cost-effective solution for data center interconnects and campus networks where 2km reach is sufficient, with lower power consumption (4.0W vs 4.5W) compared to the standard LR4.

Q: Is this transceiver compatible with other vendor equipment?
A: Yes, the QSFP-100G-LRL4 adheres to QSFP28 MSA and IEEE 802.3ba standards, ensuring interoperability with multi-vendor 100G QSFP28 ports on switches and routers from various manufacturers. However, EEPROM programming may be vendor-specific, so ensure the module is coded for your equipment.

Q: What type of fiber cable is required for this transceiver?
A: This transceiver requires duplex single-mode fiber (SMF) cable with LC connectors, typically OS2 or G.652 standard fiber. The module supports transmission up to 2km over SMF with appropriate fiber quality and connector cleanliness.

Q: Does this module support digital diagnostics monitoring?
A: Yes, the QSFP-100G-LRL4 includes DDM (Digital Diagnostics Monitoring) or DOM (Digital Optical Monitoring) functionality, allowing real-time access to operating parameters such as temperature, voltage, transmit/receive optical power, and bias current for proactive network monitoring and troubleshooting.

Q: What applications is the QSFP-100G-LRL4 best suited for?
A: This transceiver is ideal for 100G data center interconnects within 2km range, campus backbone networks, metropolitan area network (MAN) connectivity, enterprise core and distribution layer applications, and high-performance computing environments requiring medium-reach 100 Gigabit Ethernet links over single-mode fiber.
