회사 소식 Technical Aspects to Check Before Buying Hybrid FC-MPO Trunk Cables Fiber Type: Single Mode vs Multimode

Fiber Type: Single Mode vs Multimode

Decide based on distance and data rate. Single mode fiber allows longer reach and supports future upgrades. Multimode is often cheaper and sufficient for short links. Confirm that the trunk cable fiber type matches your testing or network requirements.

Fiber Count and Core Layout

Choosing 8 core or 12 core MPO depends on the transceiver or patch panel being used. Understand how many transmit and receive lanes are required. Excess core count may seem future-proof, but if unused cores are left floating, they may degrade temperature or reflectance performance.

Connector Quality and Loss Specification

FC connector performance in terms of insertion loss and return loss must be high quality. MPO connectors must align properly and maintain low skew. Loss specs should be provided in datasheets. Always verify values for both FC and MPO ends.

Jacket Material and Durability

Cable jacket and strain relief are important for mechanical stress, bend radius, environmental protection. Hybrid trunks that will be moved, tested, or used in labs must tolerate handling. Choose steel reinforced or tough jackets when needed.

Polarity and Connector Gender

Check whether MPO connector is male or female, check key up or key down orientation. FC connector type (single mode or multimode, angle polished or flat) also matters. Polarity must match equipment or patch panels.

Compatibility with Testing Standards and Tools

Ensure hybrid trunk cable can be used effectively with your measurement tools. Test sets, optical power meters, microscopes/inspection tools must support the connector types. Follow standard practices for permanent link or channel testing and adhere to insertion loss thresholds.
