Hello, will this 1.25G BiDi module work with a mix of Cisco Catalyst and Juniper EX switches?

Absolutely! This transceiver is fully MSA compliant and has been rigorously tested for seamless interoperability across major OEM brands, including Cisco, Juniper, and HPE. Just plug it in and you're good to go.

Just double-checking, does this transceiver meet standard CE and RoHS compliance for our EU facilities?

Yes, absolutely. All our optical transceivers strictly adhere to international quality standards, including CE, FCC, RoHS, and Class 1 FDA Laser Safety, ensuring full industry compliance for global enterprise deployments.

We're planning a data center mass deployment. Do you offer tier pricing if we grab 500+ units?

Yes, we highly support enterprise B2B procurement. For bulk orders over 500 units, we offer significant volume discounts. You can also contact our sales team directly to arrange custom net terms for your project.

Can I use multimode fiber with this transceiver, or is it strictly for single-mode?

This specific 1310nm-TX/1490nm-RX module is optimized strictly for Single-Mode Fiber (SMF) using a Simplex LC connector to achieve the 20km distance. Using multimode fiber will cause severe signal degradation and is not supported.

Tested in our outdoor cabinet for cell tower backhaul. Even though it's 0 to 70°C rated, it handles the summer heat fine. Great Simplex LC SMF optical transceiver for the price. ☀️
