We are planning a campus-wide fiber retrofit and need over 100 units. Do you offer tiered pricing or bulk discounts?

Absolutely. We provide tiered B2B volume pricing directly on the page starting from 100 pcs, with progressive discounts for enterprise project orders up to 6,000+ units. You can also contact our sales team directly for customized wholesale quotes, net payment terms, and official commercial invoices.

What fiber optic cable type and connector interface are required for a 10km link with this transceiver?

The LS-SM312G-10I uses a standard Duplex LC optical receptacle and is designed for standard 9/125µm Single-Mode Fiber (SMF, OS1/OS2). Using standard duplex LC-LC single-mode patch cords, it supports point-to-point optical transmission distances up to 10 kilometers (6.2 miles) at 1310nm.

Does this transceiver comply with international safety, environmental, and industry telecom standards?

Yes. The transceiver complies fully with SFP MSA, IEEE 802.3 2.5GBASE optical specifications, RoHS environmental directives, CE, FCC, and Class 1 FDA/IEC 60825-1 laser eye safety standards, meeting all compliance criteria for enterprise IT, telecom, and industrial networking deployments.

Will this 2.5G SFP module work directly in switches from brands like Cisco, Ubiquiti, MikroTik, and TP-Link without vendor lock-in errors?

Yes. The LS-SM312G-10I is built to standard multi-source agreement (SFP MSA) specifications and features universal EEPROM coding. It auto-negotiates cleanly at 2.5Gbps and provides broad plug-and-play interoperability across major enterprise switch, router, and media converter brands without requiring vendor unlock commands.

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

This module delivers identical optical link performance to original brand transceivers at a fraction of the cost. It is equipped with a high-grade 1310nm DFB laser transmitter and PIN photodiode receiver, offering precise TX power (-6 to +1 dBm), -18 dBm sensitivity, real-time DOM diagnostics, and a full 5-year warranty.
