I'm an IT procurement manager looking to deploy these in 50+ outdoor cabinets. Do you offer net terms or volume discounts for orders over 100 units?

Absolutely. For bulk data center deployments or large enterprise procurement, we offer scaled discounts, and we also support Net terms to help manage your budget. Please contact our sales team for a custom quote.

Can I use this 1310nm-TX/1550nm-RX optic with Multimode Fiber (MMF), or is it strictly for Single Mode Fiber (SMF) connections?

This particular transceiver module is engineered specifically for Single Mode Fiber (SMF) up to 10km. Using it with Multimode Fiber (MMF) is not recommended, as it will cause significant signal loss and severely limit your transmission distance.

We've had major delays with other vendors recently. If we order 500 pcs for our European data center, what is the expected lead time and supply stability?

We maintain robust inventory for our industrial SFP modules. An order of 500 pcs typically processes and ships within 3 days. Transit time to Europe via standard express shipping is usually 3 to 6 business days, ensuring stable and fast delivery for your project deadlines.

For our government contract, we need to ensure all optical transceivers meet environmental and safety regulations. Are these CE, RoHS, and FDA certified?

Yes, all our transceivers undergo a strict qualification process. They meet Class 1 FDA laser safety standards and are fully certified for CE, RoHS, REACH, and FCC. They are completely safe and compliant for global enterprise and government deployments.

Hi supplier, we are running a mix of Cisco Catalyst and Huawei switches. Will this 1G BiDi SFP work across both brands without throwing unapproved transceiver errors?

Yes! Our modules are 100% MSA compliant, and we rigorously test OEM compatibility in our lab. They provide a plug-and-play experience on both Cisco and Juniper gear without any coding headaches or system warnings.
