Planning a massive campus fiber network upgrade. Do you guys offer volume discounts for bulk purchasing these 1.25Gbps modules?

Yes, we provide competitive tiered pricing for batch deployments. For enterprise procurement of the 1G SFP BiDi transceivers over 100 units, you can expect significant discounts. Please contact our sales team directly for a custom B2B quote.

Does this 1000BASE-BX SFP meet international telecom standards and safety compliance for enterprise networking?

Yes, the LS-SC31551G-20C strictly complies with IEEE 802.3z gigabit ethernet standards, alongside RoHS, CE, and FCC certifications. You can confidently deploy them knowing they meet global safety and reliability benchmarks.

We need to deploy these in outdoor telecom cabinets. The 0-70°C rating is fine for indoors, but do you have an industrial wide-temperature version?

For outdoor deployments with extreme temperatures, we highly recommend our industrial variant, the LS-SC31551G-20I. It operates flawlessly from -40°C to 85°C while maintaining the exact same 20km transmission distance and DOM diagnostic capabilities.

Will this Simplex SC DOM SMF transceiver play nice with our mixed HP and Netgear switch environment? We need seamless interoperability.

Absolutely! The LS-SC31551G-20C 1G SFP is fully MSA compliant and extensively tested for OEM compatibility across major brands, ensuring plug-and-play operation with HP, Netgear, Cisco, and other mainstream networking equipment.
