Arista QSFP-100G-XSR4-Arista | 100G QSFP28 Transceiver, Multi-Mode, 850nm, 300m, MPO-12

Q: What fiber types are compatible with the QSFP-100G-XSR4?
A: The QSFP-100G-XSR4 supports OM3 and OM4 multi-mode fiber with an MPO-12 connector. It achieves 200m over OM3 and up to 300m over OM4 fiber, making it suitable for intra-data center connections.

Q: Can this transceiver be used for breakout applications?
A: Yes, the QSFP-100G-XSR4 supports breakout to 4x 25GBASE-SR SFP28 connections, providing flexibility for network architectures requiring lower-speed links from a single 100G port.

Q: Is the QSFP-100G-XSR4 compatible with non-Arista equipment?
A: While designed for Arista platforms, this transceiver follows industry-standard MSA specifications and IEEE 802.3bm compliance, enabling interoperability with other vendors' equipment that support 100GBASE-SR4 standard.

Q: What is the power consumption of this module?
A: The QSFP-100G-XSR4 typically consumes 3.5W, which is within the power budget for standard QSFP28 ports. Arista platforms support QSFP modules drawing up to 4.5W under normal operating conditions.

Q: Does this transceiver support digital diagnostics monitoring?
A: Yes, the module includes Digital Optical Monitoring (DOM) support via I2C interface, allowing real-time access to operating parameters such as optical power, temperature, transmit bias current, and supply voltage.
