Will this 1G SFP BiDi module plug and play with our existing Cisco Catalyst and Juniper switches, or do we need specific OEM coding?

Yes, it's fully MSA compliant and highly interoperable across multi-brand switches. For absolute certainty, you can select your specific OEM brand (like Cisco, Juniper, HPE, etc.) before purchasing, and we will flash the EEPROM to ensure flawless plug-and-play compatibility.

Is this 40km single-mode SFP compliant with standard Gigabit Ethernet and Fibre Channel protocols for our enterprise data center?

Yes, the module strictly adheres to IEEE 802.3z standards for Fast and Gigabit Ethernet, and is fully compliant with 1G Fibre Channel protocols. This guarantees industry standard compliance and safe integration into strict enterprise network environments.

The specs show a 0 to 70°C operating temperature. Do you have an industrial wide-temperature version for outdoor telecom cabinets?

Yes, the LS-BL31491G-40C is our commercial-grade indoor version. If you are deploying in harsh outdoor environments, we offer the corresponding industrial-grade model (LS-BL31491G-40I), which is engineered to operate safely in extreme temperatures ranging from -40°C to 85°C.

We're dealing with tight project deadlines. What is the standard delivery cycle for a bulk order of 500+ LS-BL31491G-40C modules to the US?

We maintain stable inventory levels to ensure supply chain reliability. An order of 500+ units is typically processed within 3 days. With standard express delivery, they will arrive at your US facility in approximately 3 to 5 business days.

Can I use a standard SC patch cord with this transceiver, or is it strictly limited to LC connectors?

This specific module features a Simplex LC optical interface to support high-density switch ports. You must use a Simplex LC-to-LC single-mode fiber patch cord. If you are connecting to older legacy equipment with SC ports, you will need a specialized LC-to-SC adapter cable.
