We are budgeting for an ISP municipal fiber project requiring 500+ units. Do you provide tiered volume discounts?

Yes, we offer transparent tiered wholesale pricing for B2B bulk orders. Tiered discounts apply automatically at checkout for quantities of 100, 1,000, 3,000, and 6,000+ pieces, lowering the per-unit cost significantly. You can also contact our sales engineering team directly to get customized B2B quotes, formal proforma invoices, and project net terms.

We run a mixed switch environment with Cisco Catalyst, Juniper EX, and MikroTik routers. Will this 1G BiDi 60km module be recognized without vendor lock-in errors?

Yes. The LS-BL31551G-60C module is fully compliant with the standard SFP MSA and SFF-8472 protocols. We also offer custom EEPROM coding for specific vendors (such as Cisco, Juniper, Arista, Dell, HPE, MikroTik, etc.). Just specify your switch hardware and OS version when requesting compatibility or ordering, and each module will be pre-coded and lab-tested to ensure plug-and-play interoperability without triggering unsupported transceiver alarms.

How does the optical performance and reliability of this transceiver compare to original OEM brand optics?

This module delivers equivalent carrier-grade optical performance and link budget specifications to major OEM brands at a fraction of the cost. It integrates a high-precision DFB laser transmitter (-5 to 0 dBm TX power) and a sensitive PIN receiver (-24 dBm sensitivity), supporting high-reliability 1.25Gbps Gigabit Ethernet transmission up to 60km with integrated Digital Optical Monitoring (DOM/DDM).
