Q: We are upgrading our campus network and need about 200 pairs. Do you offer B2B bulk pricing for large batch deployments? By A***s on 2026-05-17
A: Yes, we provide tiered volume discounts for enterprise procurement. For orders over 200 pairs, the price drops significantly, and we offer flexible Net Terms to help manage your IT budget. Please contact our live sales team for a custom quote. By admin on 2026-05-17
Q: Does this require OS2 single-mode fiber, and what connector type should my patch cords have? By S***n on 2026-04-01
A: Correct. You will need standard 9/125碌m Single-Mode Fiber (OS1 or OS2) to achieve the 120km maximum transmission distance. Make sure your fiber patch cords are terminated with a Simplex LC connector to match the optical interface of this transceiver. By admin on 2026-04-01
Q: Will this 1G BiDi SFP work if I mix Cisco Catalyst switches on one end and Juniper on the other? By M***l on 2026-03-30
A: Absolutely. Our LS-BL55491G-A2C is 100% MSA compliant. As long as you use the complementary 1490nm-TX/1550nm-RX module on the opposite end, it bridges multi-vendor equipment like Cisco, Juniper, Dell, and HPE seamlessly. By admin on 2026-03-30
Q: Are these optics compliant with standard Gigabit Ethernet and Fibre Channel protocols? I need DOM support for my SNMP monitoring. By S***z on 2026-03-14
