Does this duplex LC transceiver support multi-mode fiber (MMF), or is it strictly for single-mode fiber (SMF) setups?

This module utilizes LAN-WDM technology (1295.56nm to 1309.14nm) and is designed specifically for Single-Mode Fiber (SMF) connections to reach up to 10km. If you are looking for MMF optics for short-distance server racks, we recommend checking out our 100G SR4 modules.

Does this optical module perform identically to the official Mellanox or Huawei OEM ones? We want to lower costs but cannot risk signal drops.

You get the exact same tier-1 performance at a fraction of the cost. This transceiver utilizes a premium DFB laser and high-sensitivity PIN receiver, supporting 112Gbps throughput with strict OTU4 standards to ensure zero packet loss and identical signal integrity compared to expensive OEM optics.

The 0-70°C operating temperature is great for our indoor data center, but do you have an industrial wide-temperature version for outdoor telecom cabinets?

Currently, this specific LQ-LW112-LR4C model is commercial grade (0°C to +70°C). However, we do manufacture industrial-grade transceivers (-40°C to +85°C) designed for extreme outdoor environments. Please contact our technical support team, and we will quote you the exact industrial equivalent!

Our telecommunication infrastructure requires stringent compliance. Does this 100G/112G dual-rate module meet global MSA and Ethernet networking standards?

Yes, it is fully MSA (Multi-Source Agreement) compliant and adheres strictly to IEEE 802.3ba 100GBASE-LR4 as well as OTN OTU4 4I1-9D1F standards. It passes all global quality and compliance testing for safe telecom rollouts.

Will this LQ-LW112-LR4C QSFP28 transceiver work seamlessly in a mixed Cisco and Arista core switch environment?

Yes, absolutely! Our 100G/112G QSFP28 modules are rigorously tested for multi-vendor interoperability. They are fully compatible with Cisco, Arista, Dell, and Juniper switches without triggering any vendor lock-in warnings, making them perfect for complex enterprise architectures.
