What type of fiber cabling is required for this 100G-FR optic, and will it bridge a 1.8km link with multiple patch panels?

This module requires standard single-mode fiber (SMF, OS2/G.652D) terminated with a standard Duplex LC connector operating at 1310nm. It is designed to cover distances up to 2km (1.24 miles). With a typical optical link budget of 4dB to 5dB, it can comfortably accommodate standard fiber attenuation (~0.35dB/km at 1310nm) plus 3 to 4 intermediate patch panel mating connector insertion losses.

We need to deploy these in roadside NEMA outdoor cabinets. Can you provide an industrial wide-temperature (I-Temp -40°C to +85°C) version of this 100G-FR module?

The standard LQ-SM31100-FR1C is rated for commercial operating temperatures (C-Temp: 0°C to +70°C, typical power ~3.5W). However, for harsh outdoor environments, smart city junctions, or unconditioned telecom edge shelters, LINK-PP can manufacture an Industrial Temperature (I-Temp: -40°C to +85°C) hardened variant. Please consult our technical sales team for tailored lead time and custom P/N details.

Can we use the LINK-PP LQ-SM31100-FR1C in a mixed-vendor network with Cisco Nexus 9000 and Arista 7050X switches without tripping third-party transceiver alarms?

Yes, absolutely. LINK-PP transceivers are individually pre-coded and EEPROM-matched to your specific switch hardware. When placing your order, simply specify your target host platforms (e.g., Cisco, Arista, Juniper, Dell, NVIDIA/Mellanox, Extreme). The module reports full vendor IDs and serial strings to the host OS, ensuring seamless plug-and-play operation without port-locking or non-genuine optic error messages.

How does this single-lambda 100G-FR module compare to original OEM brand transceivers in terms of performance and reliability?

The LQ-SM31100-FR1C utilizes industry-grade 1310nm EML CW lasers and PIN receivers with advanced DSP PAM4 modulation, delivering exact 1:1 optical link budget, low Bit Error Rate (BER < 1×10⁻¹² and full DDM/DOM real-time monitoring parity with Tier-1 OEM optics. You receive equivalent enterprise-grade performance and a comprehensive 5-year warranty at a fraction of OEM OEM list prices.

Is this 100G QSFP28 FR1 transceiver compliant with global safety directives and MSA interoperability standards?

Yes. The transceiver strictly complies with the 100G Lambda MSA, IEEE 802.3cd/cu 100GBASE-FR1 specifications, and SFF-8636/SFF-8665 physical form-factor standards. Furthermore, manufacturing facilities are certified under ISO9001 and ISO14001, and every optic carries CE, FCC, RoHS (EU Directive 2015/863), and UL safety certifications.
