I need to deploy about 500 of these for a campus upgrade. Any bulk B2B discounts available?

Yes, we offer heavy tiered discounts for enterprise bulk orders! While the base price is incredibly competitive, buying in volume drops the unit cost significantly. Just reach out to our sales team for a formal B2B quote and net terms.

Specs say 0 to 70°C. Do you guys make an industrial version for unheated outdoor enclosures?

This specific model is a commercial-grade module (0 to 70°C) designed for indoor server rooms. However, we do manufacture an industrial equivalent (part number LS-SC55311G-10I) that easily handles extreme -40 to 85°C temperatures for rugged outdoor network cabinets.

Just confirming the interface—this uses a Simplex SC connector, right? So I only need one fiber strand?

Spot on! This is a WDM BiDi module featuring a Simplex SC interface. You only need a single strand of Single Mode Fiber (SMF), as it multiplexes the 1550nm transmit and 1310nm receive signals over the exact same line.

Got a mixed rack with Cisco and Ubiquiti gear. Will this 1.25G SFP module interop with both?

Absolutely! Our LS-SC55311G-10C transceiver is fully MSA compliant. We can custom-code the EEPROM for multi-vendor interoperability, ensuring it runs seamlessly on both Cisco and Ubiquiti switches without any compatibility warnings.
