A: You must use MPO-12/APC (Angled Physical Contact) fiber cables for this transceiver. The APC 8-degree polish minimizes back reflection, which is absolutely critical for maintaining signal integrity over 800G PAM4 modulation. Using UPC cables will cause severe insertion loss or potential physical damage to the optical lens. By admin
Q: Does this specific 800G module support industrial wide-temperature ranges? By W***n
A: This specific LQD-DM85800-SR8C module operates within the standard commercial temperature range of 0°C to +70°C, which is perfect for indoor, climate-controlled racks. If you require industrial wide-temp (-40°C to +85°C) versions for outdoor enclosures, please contact our support team for customized heavy-duty solutions. By admin
