Introduction

• FOSC650 is high high-capacity fiber splicing closure built on the industry-leading design of the FOSC family. It can be used in a variety of trunk and feeder applications for splicing a wide range of fibre cable types and sizes.
• The sealing system of the FOSC650 capitalizes on the well-established reliability of the FOSC450 and FOSC600 series, incorporating the versatile and widely acclaimed gel sealing technology. The dome system seamlessly seals to the closure’s base through four latches, eliminating the requirement for grease or lubricants when opening and re-entering the closure.
• FOSC650 can be deployed across a range of outdoor plant applications, serving various functions such as splicing nearly any cable type with diameters up to 1.6 inches and accommodating a remarkable 6,912 fibre splice capacity.
• The FOSC650 wide trays provide more space for spliced fibres and efficient fibre slack management. Moreover, they are fully backward compatible, enabling the utilization of FOSC-C and FOSC-D trays as well.
