L-Band Erbium Doped Fibre
YOFC's L-band erbium doped fibre (EDF) is designed to meet the major demand for DWDM
optical amplification in L-extended band communication system trunk lines. It provides a high
tail-wave gain at 1,627 nm, along with low noise and high reliability in its gain spectrum. Through
precise flow and temperature control technology, advanced material composition, and coating
design and processing techniques, we have enhanced the stability of the gain spectrum under
high phosphorus doping. This results in industry-leading gain spectrum stability within groups of
products, between groups of products, and under long-term fibre operating conditions, ensuring
consistent performance and reliability for our customers' products.
