The LUCENT ALLWEAVE BARE SINGLE MODE FIBER 30Km is a single-mode optical fiber engineered for long-distance data transmission over distances up to 30 km. This bare fiber incorporates AllWave technology, which minimizes OH ion concentration in the fiber core to virtually eliminate the water peak at 1385 nm. This design enables operation across the entire wavelength range from 1260 nm to 1625 nm, including the fifth window (1350–1450 nm), delivering expanded information capacity and flexible system configurations.
