Q: Our deployment includes roadside telecom enclosures and outdoor cabinets. Do you offer an industrial wide-temperature (-40°C to +85°C) version of this SR4 optic? By R***l on 2026-06-01
A: The standard LQ-M85100-SR4C is designed for commercial operating temperatures (0°C to +70°C / 32°F to 158°F) in standard data center and indoor server environments. However, industrial wide-temperature (-40°C to +85°C) custom configurations are available upon request for outdoor cabinets and harsh edge environments. Please reach out to our engineering team before ordering to request the industrial-grade version. By admin on 2026-06-01
Q: How does the LQ-M85100-SR4C compare to OEM brand optics (like Cisco QSFP-100G-SR4-S or H3C QSFP-100G-SR4-MM850) in terms of bit error rate and long-term reliability? By J***z on 2025-11-27
A: The LQ-M85100-SR4C delivers 100% equivalent optical performance to OEM parts at a fraction of the cost. Built with tier-1 850nm VCSEL transmitters and PIN receivers, each unit undergoes strict optical spectrum, eye pattern (mask margin > 20%), and BERT testing (< 1×10⁻¹²). It fully supports standard DDM/DOM real-time diagnostic monitoring and includes an industry-leading 5-year warranty. By admin on 2025-11-27
Q: What fiber patch cable types, polarity, and connector configurations are required to achieve the full 100-meter reach? By C***a on 2025-11-25
A: This module requires standard Multimode Fiber (MMF) terminated with an MTP/MPO-12 connector (Female, UPC polish, using the outer 8 fibers for 4x Tx and 4x Rx). Maximum reach is up to 70 meters on OM3 multimode fiber and up to 100 meters on OM4 multimode fiber when Host Forward Error Correction (FEC) is enabled. Standard Type-B (Key-Up to Key-Up) polarity trunk cables are recommended for switch-to-switch direct interconnects. By admin on 2025-11-25
Q: Can we use this 100G QSFP28 SR4 module to link a Cisco Nexus switch on one end and an Arista or Mellanox switch on the other without vendor-lock issues? By B***z on 2025-10-08
A: Yes, absolutely. We provide custom EEPROM vendor coding before shipment. You can specify the exact host switch models (e.g., Cisco, Arista, NVIDIA/Mellanox, Juniper, Dell, etc.) during checkout or via direct message, and each transceiver will be custom-coded and host-tested to guarantee seamless cross-platform interoperability without triggering unsupported transceiver alarms. By admin on 2025-10-08
Q: Does this transceiver comply with standard industry MSA specifications and international regulatory certifications? By C***g on 2025-08-01
A: Yes. The module strictly complies with QSFP28 MSA, SFF-8636, IEEE 802.3bm (100GBASE-SR4), and CAUI-4 electrical interfaces.
