A blade arrangement for use in a bladed chassis system includes a splice module coupled to a blade. The splice module includes a splice region, a storage region, a first enter/exit region at the first side, and a second enter/exit region at the second side. Either of the enter/exit regions can be faced towards a rear of the blade when the splice module is mounted to the blade. The splice allows unterminated optical cables routed to the rear of the blade to be optically spliced to connectorized pigtails that are received at rear ports of optical adapters on the blade.
