I'm looking to roll out around 300 units for a new campus network upgrade. Do you guys offer volume discounts for bulk data center deployment?

Absolutely. We have tiered pricing tiers tailored for bulk purchases. For a 300-piece rollout, please hit up our sales team via Live Chat or email, and we’ll get you a solid customized quote to ensure you get the best price-per-port value.

Hi guys, we run a mixed rack of Cisco Catalyst and Arista switches. Will this LS-SC31491G-20C module trigger any "unsupported transceiver" warnings?

No worries there! This 1G BiDi SFP strictly complies with SFP MSA standards and is thoroughly tested for multi-vendor interoperability. It’s truly plug-and-play on Cisco, Arista, Juniper, and most major switch brands without throwing any OEM vendor lock-in errors.

Is the DOM feature fully compliant with SFF-8472? We need accurate real-time diagnostic readings for our central monitoring system.

Yes, it is fully SFF-8472 compliant. The built-in Digital Optical Monitoring (DOM/DDM) accurately reports real-time telemetry on temperature, voltage, laser bias current, and TX/RX optical power, integrating smoothly with your NMS for proactive maintenance.
