This module operates at 0 to 70°C, but we need optics for outdoor cabinets in harsh winters. Do you have an industrial wide-temperature version of this 40km BiDi SFP?

Yes, we do! For extreme environments, we manufacture an industrial-grade version (model LS-BL55311G-40I) which operates flawlessly in temperatures ranging from -40°C to 85°C. It is perfectly suited for cell tower backhaul and unconditioned outdoor enclosures.

We run a mixed environment with Cisco Catalyst and Juniper EX series switches. Will this LS-BL55311G-40C module require any special CLI commands to bypass vendor lock-in?

No special CLI commands are needed. This 1G BiDi SFP is strictly MSA compliant and rigorously tested for seamless interoperability across major network equipment brands, including Cisco and Juniper, providing a true plug-and-play experience.

I want to upgrade our legacy network. Can I use OM3 multimode fiber with this specific 1G optic, or is it strictly for single-mode fiber?

This LS-BL55311G-40C module is designed specifically for Single Mode Fiber (SMF) to reliably achieve the 40km transmission distance. Using multimode fiber like OM3 is not recommended, as it will cause severe modal dispersion and drastically reduce your link distance.

I'm planning a data center mass deployment and need about 1K units. Do you offer any tiered discounts for bulk purchasing on these 40km SMF optics?

Absolutely! We offer highly competitive tiered pricing for bulk B2B procurement. For an order of 1K units, our per-unit cost drops significantly compared to the standard retail price. Please contact our sales team directly to lock in your discount.
