• MPO and MTP Fiber Optic Connectors
MPO is short for Multi-fiber Push On, the first generation of multi-fiber optical connector developed by NTT Japan.
Its key industrial standards include IEC-61754-7, Chinese standard YD/T 1272.5-2009, and US standard TIA-604-5.
MTP stands for Multi-fiber Termination Push-on and is a registered trademark of US Conec.
It is a high-performance enhanced version of the MPO connector, with a number of patented design optimizations for better mechanical and optical performance.
MTP connectors fully comply with all standard MPO specifications and can be regarded as a premium grade of MPO connector.
• Key Differences Between MTP and MPO
1. Housing Marking
MTP connectors are clearly marked with US Conec on the outer housing. All unmarked multi-fiber push-on connectors are standard MPO types.

2. Pin Retainer Design
MTP patch cord connectors typically use metal pin retainers to securely hold guide pins, greatly reducing the risk of accidental breakage during installation and use.
Standard MPO connectors use plastic pin retainers, which are less durable and more likely to cause pin damage.

3. Guide Pin Structure
Unlike single-fiber connectors, multi-fiber connector adapters only provide rough alignment, making precision guide pins essential for accurate MT ferrule mating.
• MTP connectors use precision stainless steel round guide pins with tight fixation, minimizing debris accumulation on guide holes and ferrule end faces.
• Standard MPO connectors use common cylindrical guide pins, which tend to generate more debris during mating and use.
