Nortel N0108946 (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel N0108946 is a fixed fibre optic attenuator, LC/UPC terminated, rated at 5dB, built by Amphenol in the same 956-130-5xxx-R series as the 7dB variant Amphenol also supplies (956-130-5307), the same family, a different fixed attenuation value. Fixed attenuators like this one are inserted into a single-mode fibre link to reduce optical power reaching a receiver, which protects the receiver from saturation and keeps the link within its specified dynamic range on short runs or high-power transmitters where the natural fibre loss is not enough on its own. The LC/UPC termination matches the low-back-reflection connector standard used across most of this catalogue’s current-generation Nortel optical transport equipment. Genuine attenuators of a confirmed, fixed dB value such as this one are a routine requirement when commissioning or re-balancing an optical link, since guessing the wrong value risks either saturating the receiver or leaving the link under-attenuated.
