FAQs

Q: What is the difference between QSFP-100G-PLRL4 and QSFP-100G-LR4?
A: The PLRL4 uses an MPO-12 connector for parallel single-mode fiber with a 2km reach, while the LR4 uses a duplex LC connector and supports up to 10km reach. The PLRL4 also supports breakout to 4x 25G-LR configurations.

Q: Can this transceiver be used in a breakout configuration?
A: Yes, the QSFP-100G-PLRL4 supports breakout to 4x 25G-LR and is dual-rate capable for 100G/40G operation over parallel single-mode fiber.

Q: What platforms support the QSFP-100G-PLRL4 transceiver?
A: This transceiver is compatible with Arista 100G QSFP28 ports on platforms designed to handle transceivers drawing up to 4.5W. Consult the Arista Transceivers and Cables Guide for specific platform compatibility.

Q: Does this transceiver support digital diagnostics monitoring?
A: Yes, the QSFP-100G-PLRL4 supports DDM/DOM functionality via the I2C interface, providing real-time access to operating parameters such as temperature, voltage, optical power, and more.

Q: What type of fiber cable is required for this transceiver?
A: The QSFP-100G-PLRL4 requires parallel single-mode fiber (SMF) with an MPO-12 APC connector, rated for operation up to 2km distance.
