ʻO ke kiʻekiʻe o ka wai haʻahaʻa non-dispersive displacement single-mode fiber i kūpono no ka hoʻouna ʻana i ka ʻōnaehana o ka hui piha 1280nm ~ 1625nm, ʻaʻole ia e mālama wale i ka haʻahaʻa haʻahaʻa o ka hui kuʻuna 1310nm, akā he haʻahaʻa haʻahaʻa ma 1383nm, e hana ana i ka E band. (1360nm ~ 1460nm) hoʻohana piha. ʻO ka nalowale a me ka hoʻopuehu ʻana o ka hui holoʻokoʻa mai 1260nm a i 1625nm ua hoʻemi ʻia, a ua hoʻemi ʻia ka nalo ʻana o ka nalu 1625nm, e hāʻawi ana i nā kumuwaiwai bandwidth no ka ʻupena iwi kuamoʻo, MAN a me ka pūnaewele komo.
