Arista QSFP-100G-SRBD-Arista | 100G BiDi Transceiver, 850nm, 100m OM4, Duplex LC

Q: What is the key advantage of the QSFP-100G-SRBD BiDi transceiver?
A: The BiDi design allows 100 Gbps transmission over standard duplex multimode fiber, eliminating the need for expensive parallel fiber infrastructure while reusing existing 10G/40G duplex cabling. Each LC port transmits and receives simultaneously at 50 Gbps per fiber.

Q: Can this transceiver interoperate with 400G platforms?
A: Yes, the QSFP-100G-SRBD interoperates with Arista 400G BiDi transceivers (OSFP-400G-SRBD and QDD-400G-SRBD) in breakout configurations, where a single 400G BiDi module can support 4x 100G SRBD connections. However, it must be deployed in book-ended configurations with matching SRBD or SR1.2 optics on both ends.

Q: What fiber types and distances does this support?
A: The QSFP-100G-SRBD supports OM3 multimode fiber up to 70 meters and OM4 multimode fiber up to 100 meters, making it suitable for short-reach data center, campus, and enterprise core deployments.

Q: Is this compatible with all Arista 100G QSFP ports?
A: Yes, the QSFP-100G-SRBD is supported on all Arista QSFP 100G ports. It is hot-pluggable and complies with QSFP28 MSA standards for broad platform compatibility.

Q: Does this transceiver include diagnostic monitoring?
A: Yes, DDM (Digital Diagnostics Monitoring) is supported, allowing real-time monitoring of operating parameters such as optical power, temperature, and voltage for proactive network management.
