Q: How does the optical performance and bit error rate (BER) of this BiDi module compare to OEM original Cisco or Arista 100G optics? By N***s on 2026-07-11
A: The LQ-BLA100-L21C is built with high-grade EML lasers, sensitive PIN photodetectors, and onboard KP4 FEC, fully compliant with IEEE 802.3bm and 100G Lambda MSA standards. It delivers the exact same optical budget (>6.5dB), insertion loss tolerance, latency, and pre-FEC/post-FEC BER performance as OEM optics at a fraction of the cost, backed by a comprehensive 5-year warranty.

Q: What type of fiber patch cord do I need, and can two LQ-BLA100-L21C modules connect directly to each other? By C***l on 2025-11-30
A: You will need a standard Single-Mode Fiber (OS2 SMF, 9/125µm) with a Simplex LC/UPC connector. Note that you cannot connect two identical A-end (LQ-BLA100-L21C) units together. A bidirectional link requires one LQ-BLA100-L21C (TX 1291nm / RX 1311nm) at Site A and one LQ-BLB100-L21C (TX 1311nm / RX 1291nm) at Site B to complete the optical circuit on a single fiber strand. By admin on 2025-11-30
Q: We need to deploy these in non-climate-controlled roadside cabinets. Do you offer an industrial wide-temperature (-40°C to +85°C) version? By A***s on 2025-11-22
A: The standard LQ-BLA100-L21C is rated for commercial operating temperatures (0°C to 70°C). However, for outdoor telecom enclosures, 5G fronthaul/backhaul poles, and rugged industrial plants, we offer an Industrial Temperature (I-Temp, -40°C to +85°C) build upon request. Please contact our support team before placing your order to specify the industrial-grade requirement. By admin on 2025-11-22
Q: Can this 100G QSFP28 BiDi transceiver interoperate between a Cisco Nexus switch on one side and an Arista 7050 on the other? By D***s on 2025-10-12
A: Yes, absolutely. We can custom-code the EEPROM for each end—encoding one unit for Cisco (e.g., Nexus 9000 series) and the complementary unit for Arista. As long as you pair the LQ-BLA100-L21C (1291nm-TX/1311nm-RX) with the complementary LQ-BLB100-L21C (1311nm-TX/1291nm-RX), the physical optical link and 100GBASE-BX20 signaling will interoperate seamlessly with full DDM support across multi-vendor hardware.
