We are planning a regional substation network upgrade. Do you offer volume tier pricing or project discounts for bulk orders over 500 units?

Absolutely. We offer tiered bulk pricing directly on the product page (ranging from single-unit pricing down to tiered volume discounts for 100, 1,000, and 3,000+ units). For enterprise rollouts or tender bids requiring customized packaging and scheduled batch shipments, our B2B sales team can provide formal commercial quotes and net payment terms.

Will this 1G BiDi SFP transceiver work seamlessly with our existing Cisco Catalyst, Juniper, and MikroTik switches without triggering unsupported transceiver alarms?

Yes. The LS-BL55491G-A5I is built strictly to standard SFP MSA specifications and comes pre-coded for universal multi-vendor interoperability. It supports full hot-swapping and communicates transparently via SFF-8472 digital diagnostics across Cisco, Juniper, Arista, MikroTik, Ubiquiti, and other mainstream networking equipment without throwing proprietary locking errors.

Which fiber patch cable and matching mating transceiver do I need to establish a complete 150km BiDi connection?

This module requires standard Single Mode Fiber (OS2 SMF, 9/125μm) terminated with a Simplex LC connector. Because it transmits at 1550nm and receives at 1490nm (1550nm-TX / 1490nm-RX), the remote end of your fiber link must be fitted with the complementary mating transceiver: LINK-PP part number聽LS-BL49551G-A5I聽(1490nm-TX / 1550nm-RX 150km Industrial).

Does this optical module comply with international telecom standards, laser safety classifications, and environmental directives?

Yes. The transceiver strictly adheres to IEEE 802.3ah 1000BASE-BX, SFP MSA, and SFF-8472 standards. It is certified Class 1 Laser Safety compliant under IEC 60825-1, as well as CE, FCC, and RoHS compliant, fulfilling all enterprise compliance and data center deployment prerequisites.
