Are these single-mode fiber modules fully compliant with global telecom and industry networking standards?

Yes. The LS-BL55311G-02C is fully MSA (Multi-Source Agreement) compliant and meets strict IEEE 802.3z Gigabit Ethernet standards. It also complies with international safety and environmental regulations, ensuring safe, compliant, and reliable enterprise operation.

The specs mention an operating temperature of 0 to 70°C. Do you have an industrial-grade version for extreme outdoor cabinet deployments?

This specific LS-BL55311G-02C model is designed for commercial indoor or temperature-controlled environments (0 to 70°C). If your outdoor deployment experiences extreme weather, we offer an industrial version (-40°C to 85°C) with the exact same 2km reach and DDM features. Just search for the "LS-BL55311G-02I" suffix version on our site.

Our current patch panels are LC UPC. Is this 2km optical transceiver compatible with our standard LC patch cables?

Yes, this module features a standard Simplex LC interface. It perfectly matches standard LC UPC single-mode fiber (SMF) patch cables, ensuring secure physical connections with minimal insertion loss for your 1.25Gbps uplinks.

I'm planning a large campus fiber rollout and need about 500 units. Do you offer volume discounts for bulk procurement?

Yes, we provide aggressive tiered pricing for bulk orders. For an order of 500 pieces, you'll receive a significant discount off the standard unit price, greatly lowering your total deployment costs. Please contact our sales team directly for your custom B2B quote.

We run a mix of Cisco and Juniper switches in our data center. Will these 1G BiDi SFPs work seamlessly without triggering third-party optic warnings?

Absolutely! The LS-BL55311G-02C is strictly MSA compliant and undergoes rigorous multi-brand switch compatibility testing. It perfectly integrates with Cisco, Juniper, and other major OEM networking equipment without triggering unsupported transceiver errors.
