Will this 1G BiDi SFP play nice with my Cisco Catalyst and Juniper switches? We need to mix brands.

Absolutely. It's fully MSA compliant and tested for cross-brand interoperability. You can seamlessly deploy it across major OEM switch brands without vendor lock-in issues.

Does this use a Simplex or Duplex LC connector? We are trying to cut down on fiber usage.

It features a Simplex LC connector. By using WDM technology (1490nm-TX/1550nm-RX), it transmits and receives over a single strand of Single Mode Fiber (SMF), which instantly doubles your existing fiber capacity.

We're planning a massive base station backhaul upgrade. Do you guys offer discounts if we order 1,000+ units?

Yes, we do! For bulk procurement and large-scale deployments, we offer tiered pricing. Please reach out to our sales team directly, and they’ll get you a custom quote that fits your project budget.

Does this optic meet industry standards like SFF-8472 for digital diagnostics?

Yes, it strictly complies with industry standards and supports SFF-8472. The built-in DOM/DDM allows your network admins to precisely monitor voltage, temperature, and optical power in real-time.
