No, the LS-SM552G-80I is a fixed 2.5Gbps rate optical transceiver designed specifically for 2.5G SFP / SFP+ ports or multi-rate ports manually configured for 2.5G operation. It does not support automatic rate fallback to 1000BASE-X 1.25G unless the host port explicitly supports manual rate forcing. by LINK-PP Technical Support
Yes, an optical attenuator is strongly recommended when bench testing this module over short fiber cables. Because the LS-SM552G-80I utilizes a high-gain APD (Avalanche Photodiode) receiver and a DFB transmitter outputting up to +3dBm, plugging it directly into a short patch cable without at least 10-15dB attenuation can saturate or permanently damage the sensitive APD receiver. by LINK-PP Technical Support
Industrial-grade modules are equipped with hardened components, internal thermal compensation algorithms, and industrial-rated laser diodes designed to handle extreme temperature fluctuations. This prevents optical frequency drift, laser degradation, and link dropouts when deployed in unconditioned outdoor cabinets, roadside enclosures, or industrial plants. by LINK-PP Technical Support
Yes, the module features built-in DDM/DOM functionality compliant with SFF-8472.
