Q: Will these 100G QSFP28 100km optical transceivers work seamlessly in our Cisco Nexus 9000, Arista 7050X, and Juniper QFX switches without vendor lock-in warnings? By A***z on 2026-03-23
A: Yes, absolutely. Each LINK-PP LQ-LW100-A04C module is custom-coded with OEM-specific EEPROM tables for Cisco, Arista, Juniper, Dell, Brocade, Extreme, and generic MSA switches. They deliver seamless plug-and-play compatibility, full SFF-8636 compliance, and native CLI recognition with accurate DOM diagnostics. By admin on 2026-03-23
Q: What type of fiber cable and patch cord interface is required to reach the full 100km distance without intermediate optical amplification? By S***g on 2026-01-21
A: The module requires standard Duplex LC single-mode fiber (SMF, ITU-T G.652). Thanks to the integrated high-gain SOA receiver and 1310nm LAN-WDM lanes (1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm), it transmits over unamplified optical links up to 100km, provided total link insertion loss remains within the transceiver's optical power budget. By admin on 2026-01-21
Q: Does this transceiver comply with formal optical industry standards, IEEE specifications, and environmental safety regulations? By P***z on 2025-09-18
A: Yes. The transceiver fully complies with QSFP28 MSA, IEEE 802.3ba 100GBASE Ethernet standards, SFF-8636 management protocols, and RoHS-10 / CE / FCC environmental directives. It is also backed by our 5-year hardware warranty and 30-day return policy. By admin on 2025-09-18
Q: How does this LQ-LW100-A04C module compare to original brand 100GBASE-ZR4+ optics in terms of transmission reliability and signal integrity? By J***l on 2025-06-08
A: The transceiver utilizes high-grade EML lasers, integrated LAN-WDM MUX/DEMUX filters, dual CDRs, and a high-sensitivity SOA+PIN receiver. It provides the exact same aggregate 103.125Gbps line rate, tight optical eye-diagram compliance, and ultra-low Bit Error Rate (BER) as Tier-1 OEM optics, but at a fraction of the cost. By admin on 2025-06-08
Q: We have outdoor roadside cabinets and edge cell sites. Do you provide an industrial wide-temperature (-40°C to +85°C) version of this 100km transceiver? By D***n on 2025-02-13
A: The standard LQ-LW100-A04C model is engineered for commercial operating temperatures (0°C to +70°C). We also manufacture industrial-grade (-40°C to +85°C) long-haul optical transceivers for hardened outdoor cabinets, telecom base station backhaul, and harsh environments upon customer specification.
