Arista QSFP-40G-LRL4-Arista | 40G QSFP+ Transceiver, Single-Mode, 1310nm, 2km, LC

Q: What is the maximum transmission distance for the QSFP-40G-LRL4?
A: This transceiver supports up to 2km over single-mode fiber (OS1/OS2) at 40 Gbps. It uses a 1310nm wavelength and duplex LC connectors, making it suitable for medium-reach data center and campus interconnects.

Q: Is this transceiver compatible with non-Arista network equipment?
A: Yes, the QSFP-40G-LRL4 is MSA-compliant and can work with other vendors' equipment that supports 40GBASE-LR4 standards. However, for best results and full compatibility, verify with your equipment manufacturer.

Q: Does this module support digital diagnostics monitoring?
A: Yes, the transceiver includes DOM (Digital Optical Monitoring) support via the I2C interface, allowing real-time monitoring of optical power, temperature, voltage, and other operating parameters for proactive network management.

Q: What type of fiber cable is required for this transceiver?
A: The QSFP-40G-LRL4 requires single-mode fiber (SMF) cable with duplex LC connectors. It is designed for use with OS1 or OS2 grade fiber to achieve the rated 2km distance at 40 Gbps.

Q: Can this transceiver be hot-swapped during operation?
A: Yes, this QSFP+ module is hot-swappable, allowing you to install or remove it without powering down the network equipment, minimizing downtime during maintenance or upgrades.
