What fiber cable type and optical attenuation budget are required to achieve the full 120km reach?

The LS-SM5506-A2I is engineered for standard 9/125µm Single-Mode Fiber (SMF, OS1/OS2) using Duplex LC connectors. It delivers an optical link budget of approximately 28dB to 33dB (TX 0~+5dBm, RX sensitivity -28dBm, overload -1dBm). Please note: on shorter test loops or spans under 40km, inline optical attenuators must be used to protect the high-sensitivity receiver from saturation.

Will the LS-SM5506-A2I work smoothly in our Cisco, Juniper, and Ciena SDH/SONET chassis without triggering vendor lock or unsupported transceiver alarms?

Yes. Our LS-SM5506-A2I transceivers are pre-coded and rigorously tested for full interoperability across tier-1 networking vendors including Cisco (ONS-SI-622-SR/LR equivalents), Juniper, Ciena, Huawei, and Alcatel-Lucent. Custom EEPROM encoding is available upon checkout to guarantee seamless plug-and-play recognition without needing CLI service bypass commands.

Does this transceiver comply with formal optical transport standards, MSA agreements, and environmental regulations?

Yes. The module is fully compliant with the standard SFP Multi-Source Agreement (MSA), SFF-8472 digital diagnostic interface, and ITU-T / SONET OC-12 / SDH STM-4 specifications. All hardware is RoHS compliant, CE/FCC certified, and covered by LINK-PP’s 5-year replacement warranty.
