We run a mixed environment with Cisco Catalyst and Juniper EX series switches. Will this 1G BiDi SFP work smoothly across different OEM brands?

Absolutely! The LS-BL55491G-10C is fully MSA compliant and programmed for broad OEM compatibility. It seamlessly interoperates with Cisco, Juniper, Ubiquiti, and other major brands right out of the box without any software lockouts.

Will this transceiver work with multimode fiber, or is it strictly for single-mode fiber (SMF)? Can it use standard LC patch cords?

This specific module is engineered strictly for Single-Mode Fiber (SMF) to ensure reliable, high-speed transmission up to 10km. It features a Simplex LC interface, meaning you just need a standard Simplex LC single-mode patch cable to connect this DOM optical transceiver successfully.

Our data center needs to deploy over 500 units for a massive network upgrade. Do you offer volume discounts for bulk procurement?

Yes, we definitely do. While our single-unit price is highly competitive, we provide tiered pricing. For orders over 100 units the price drops automatically, and for 500+ units, please contact our sales team directly for an exclusive bulk discount quote to maximize your project budget.

Does this transceiver meet standard industry regulations for enterprise telecom environments?

Yes, it strictly adheres to Fast Ethernet and Gigabit Fibre Channel standards, complies with the IEEE 802.3ah protocol, and is fully RoHS compliant. It's built for commercial-grade network reliability, making it perfectly safe and compliant for any telecom backhaul or enterprise backbone.

This module operates from 0 to 70°C. We have some outdoor cabinets in harsh weather. Do you offer an industrial-grade version with a wider temperature range?

Yes! While the LS-BL55491G-10C is commercial grade (0 to 70°C), we also manufacture the LS-BL55491G-10I, which is the exact industrial equivalent. It supports extreme temperatures from -40°C to +85°C, making it perfect for outdoor enclosures, cell towers, and rugged environments.

Squeezing more capacity from existing single-mode fiber was crucial. Dropped these 1550nm DFB transceivers into our remote base station links. 10km reach is perfectly accurate with fantastic TX/RX optical power margins.
