PK56A series no boa asorɔkye tenten nhyehyɛe ason a ɛkata fiber nkitahodi asorɔkye tenten titiriw no so: 850nm (asorɔkye tenten tiawa ma multimode fiber), 1310nm (zero-dispersion asorɔkye tenten ma single-mode fiber), 1490nm (CATV downstream wavelength), 1550nm (lowest-loss wavelength ma single-mode fiber), 1610nm ne 1625nm (out-of-band sɔhwɛ asorɔkye tenten ma DWDM nhyehyɛe ahorow). Saa asorɔkye tenten ason yi kata spectrum no nyinaa so fi akwan tiaa multimode so kosi akyirikyiri single-mode so, efi access networks so kosi trunk networks so.
Mfaso a mfaso wɔ so a ɛwɔ asorɔkye tenten ason a wɔde kata so ne sɛ afuw mu mfiridwumayɛfo nhia OPM ahorow mma nhyehyɛe ahorow.

Fiber interface ahorow no gu ahorow — ahorow a wɔtaa de di dwuma no bi ne FC (threaded, wɔtaa de di dwuma wɔ CATV ne sɔhwɛ mfiri mu), SC (push-pull, wɔtaa de di dwuma wɔ telecom mfiri ne data centers), ST (push-pull, wɔtaa de di dwuma wɔ network mfiri dedaw mu), ne LC (push-pull nketewa, a wɔtaa de di dwuma wɔ high-density data centers). Nhyehyɛe ahorow de interface ahorow ahorow di dwuma. Sɛ OPM boa interface baako pɛ a, adapter nsakraeɛ bɛyɛ nea ɛtaa ba wɔ afuo no mu.
