I'm looking at a massive machine room batch deployment and need around 500 units. Do you offer any volume discounts for B2B procurement?

We sure do! For large-scale fiber network deployments, we provide tiered B2B pricing. You can apply our bulk coupon codes at checkout or contact our sales team directly for a custom quote.

Our enterprise requires strict adherence to industry standards for data center interconnects. Is this 1550nm-TX/1310nm-RX optic fully compliant with SFF-8472 and standard safety protocols?

Definitely. It fully complies with the SFF-8472 standard for Digital Diagnostic Monitoring, along with strict RoHS, CE, and FCC global compliance, ensuring safe and standardized integration into your network.

Can you confirm the exact fiber interface? We want to make sure it matches our existing campus single-mode fiber runs.

This module uses a Simplex SC connector interface. Since it utilizes WDM technology for bidirectional transmission, you only need one single-mode fiber (SMF) strand per link to reach the full 3km distance.

Hi guys, we run a mix of Cisco, Juniper, and Ubiquiti gear in our server rooms. Will this 1G BiDi SFP module play nice with all of them without throwing third-party optic errors?

Yes, absolutely! This transceiver is strictly SFP MSA compliant and designed for seamless multi-brand switch compatibility. Just plug it in, and it’s recognized instantly like the OEM optic.
