Will this 1G BiDi module play nice with a mix of Cisco Catalyst and Ubiquiti EdgeSwitches?

Absolutely! The LS-BL31491G-40I is 100% MSA compliant. We've extensively tested it for cross-brand interoperability, so you can seamlessly link your Cisco and Ubiquiti gear without throwing any frustrating "unsupported transceiver" errors.

We have outdoor telecom enclosures that hit 80°C in the summer and -30°C in winter. Can this optic survive without active cooling?

Definitely. This is a true industrial-grade module specifically engineered for extreme outdoor environments. It supports a wide operating temperature range of -40°C to 85°C, making it perfect for unventilated cabinets and harsh cell tower deployments.

We're looking to deploy about 300 of these for a city-wide campus network. Do you guys offer any volume discounts?

Yes, we provide tiered pricing for bulk rollouts! For a procurement batch of 300 units, you'll see a significant drop in the per-unit cost. Just hit up our sales team via live chat or email to get a custom wholesale quote.

Does this transceiver support standard DDM/DOM for SNMP monitoring? Need to ensure it meets our data center compliance.

Yes, it fully supports DDM (Digital Diagnostic Monitoring) per the SFF-8472 standard. Your network management system can easily pull real-time data on optical TX/RX power, voltage, and laser temperature via SNMP to maintain industry compliance.
