Hello, will this 1G BiDi SFP work smoothly with Cisco and Juniper edge switches? We need seamless interoperability for a multi-brand setup.

Yes! It is fully MSA compliant and extensively tested for OEM compatibility across major brands like Cisco, Juniper, and Arista, ensuring flawless multi-brand switch interoperability for your network.

does this require single-mode fiber, and do I need to pair it with a specific module on the other end?

Spot on! It requires Single-Mode Fiber (SMF) adapted to a Simplex SC interface. Because it transmits at 1310nm and receives at 1550nm, you must pair it with a complementary 1550nm-TX/1310nm-RX transceiver on the other side.

We are planning a massive campus fiber network upgrade. Do you offer bulk purchase discounts for these Simplex SC transceivers?

Absolutely. We provide tiered volume discounts specifically for enterprise procurement and large-scale server room bulk deployments. Just reach out to our sales team with your exact quantity for the best rates!

Is this 3km SMF SFP module fully compliant with IEEE 802.3ah and RoHS standards? We have strict industry compliance requirements.

Definitely. It fully meets IEEE 802.3z and 802.3ah gigabit standards and is 100% RoHS compliant, ticking all the necessary boxes for global industry regulations and safe environmental practices.
