Environmental Adaptability: Works in -40°C to +75°C (operating) and -40°C to +85°C (storage), 5%-95% non-condensing humidity, compliant with IEC 60869-1 and Telcordia GR-910-CORE.
Main Applications: CATV/broadcast networks, FTTH/FTTx deployments, optical test setups, telecom/data center fiber links needing precise power leveling.
This is a fixed, bulkhead-style fiber optic attenuator adapter designed for single-mode fiber networks. It integrates a precision attenuation element within an SC/APC adapter housing, providing a fixed 5dB optical loss while enabling seamless fiber connection. The green housing indicates the APC (Angled Physical Contact) polish type
