For single-mode applications requiring large fiber counts, lightguide ribbon-type cable provides an extremely compact and rugged design. The fiber density is extremely high, allowing for up to 144 fibers in a sheath with a diameter of <0.5 in. The design provides excellent optical performance of 1310 and 1550 nm. For long-haul applications requiring maximum repeater spacing, minimum splice loss may be obtained through individual fiber splicing using bonding, fusion, or mechanical techniques. In most metropolitan trunk or loop applications, where splice loss requirements are less critical, splicing time can be greatly reduced by using factory installed array connectors. With array splicing, 144 singlemode fibers can be spliced in <3 h by craft personnel.
