Arista QSFP-100G-PLRL4 | 100G QSFP28 Transceiver, Single-Mode, 1310nm, 2km, MPO

Q: Can the QSFP-100G-PLRL4 be used for breakout applications?
A: Yes, this transceiver supports breakout to 4x 25GBASE-LR for connections up to 2km, as well as 4x 10G breakout. Care must be taken to use the same forward error correction (FEC) mode on both ends to establish link-up.

Q: What type of fiber cable is required for the QSFP-100G-PLRL4?
A: This module requires parallel single-mode fiber (SMF) with an MPO-12 APC connector. The connector uses guide pins to ensure proper alignment with the transceiver receptacle.

Q: Is the QSFP-100G-PLRL4 compatible with all Arista 100G platforms?
A: The QSFP-100G-PLRL4 operates at 3.5W and is supported on all Arista 100G QSFP ports, which are designed to handle transceivers drawing up to 4.5W. Consult the Arista Transceivers and Cables Guide for specific platform compatibility.

Q: What is the difference between QSFP-100G-PLRL4 and QSFP-100G-PSM4?
A: The QSFP-100G-PLRL4 supports 2km reach over single-mode fiber, while the PSM4 variant supports up to 500m. Both use 1310nm wavelength and MPO connectors, but PLRL4 offers extended distance for larger data center deployments.

Q: Does this transceiver support InfiniBand protocols?
A: Yes, the QSFP-100G-PLRL4 is compliant with InfiniBand EDR, FDR, and QDR interconnects in addition to 100G Ethernet applications, making it suitable for both networking and high-performance computing environments.
