The new fibers round out Lightera’s CPO fiber portfolio by adding 80 µm cladding options alongside existing 125 µm class solutions, giving device and system designers greater flexibility to optimize packaging density, routing, and alignment in next-generation optical engines and switch architectures.

The Micro Connect 1310 fibers are optimized for 1310 nm O-band operation, balancing higher-order mode suppression and very low bend loss to maintain signal fidelity in tight routing environments. While primarily designed for co-packaged optics, the fibers are also well suited for compact O-band pluggables and miniaturized photonic devices.

To support high-density attach schemes, the coating diameter is set at 125 µm, enabling compatibility with 127 µm pitch devices while avoiding the complexity of interleaving fibers in dense arrays.

“Co-packaged optics platforms push fiber performance and dimensional control to a new level,” said Rasmus Jensen, Product Market Manager, Specialty, Global Marketing & Sales, Lightera. “With our new Micro Connect 1310 80/125 SMF and PMF, we are delivering fibers specifically optimized for O-band CPO environments — combining tight bend performance, modal control, and array-friendly geometry. This launch complements our CPO fiber suite and gives customers both 80 µm and 125 µm cladding options to match their integration strategy.”

Key features include:

• O-band optimization for CPO and short-reach high-speed links
• Low bend loss for tight routing environments
• Higher-order mode suppression for improved signal integrity
• Available in SMF and PMF variants
• 125 µm coating diameter for 127 µm pitch compatibility
• Designed for high-density fiber attach arrays and compact modules

Micro Connect 1310 80/125 SMF and PMF fibers are available for customer qualification.
