We have outdoor telecom cabinets and edge computing enclosures. Is an industrial wide-temperature (-40°C to +85°C) version available for this 2km CWDM4 transceiver?

Yes, while the standard unit operates under commercial temperature ranges (0°C to 70°C), we also supply industrial-grade (I-Temp, -40°C to 85°C) customized versions specifically built for harsh outdoor telecom base stations and non-temperature-controlled edge cabinets.

We are upgrading our enterprise datacenter spine-leaf fabric and need over 120 units. Do you provide tiered bulk discount pricing and project quotation support?

Yes, we offer tiered volume pricing, dedicated corporate account managers, and formal B2B invoicing for high-density datacenter rollouts. Feel free to submit your bill of materials (BOM) to our enterprise sales desk for custom project pricing.

Can we use this 100G CWDM4 QSFP28 module to interconnect a Cisco Nexus 9300 on one end and an Arista 7050X3 on the other without EEPROM vendor-lock errors?

Yes, absolutely. We provide vendor-specific EEPROM customization for Cisco, Arista, Juniper, Dell, Mellanox, and generic MSA architectures. Both ends will recognize the transceivers natively without CLI compatibility warnings or port shutdown issues.

How does the optical performance and bit error rate (BER) of this CWDM4 transceiver compare to original OEM modules like Cisco QSFP-100G-CWDM4-S?

The transceiver utilizes high-grade 4-channel uncooled DFB laser arrays (1271/1291/1311/1331nm) and high-sensitivity PIN receivers that strictly match original OEM electrical and optical specifications. You achieve the same line-rate 100Gbps throughput, low latency, and real-time DOM monitoring at a fraction of the OEM cost.

Is this transceiver fully compliant with international datacenter standards, CWDM4 MSA, and environmental regulations for North America and Europe?

Yes, the module complies fully with CWDM4 MSA, IEEE 802.3ba 100GBASE-CWDM4, SFF-8665, and SFF-8636 standards. It carries CE, FCC, and RoHS certifications, manufactured under ISO9001, ISO14001, and ISO45001 certified facilities.

Deployed fifty LQ-CW100-FR4C units for our datacenter interconnect fabric. Power draw averaged 3.1W per transceiver, DOM reporting perfectly matched our Calnex test gear, and Arista EOS recognized the EEPROM coding immediately without warning flags.
