12-Fiber OP (MPO) to OP MPO Single-Mode Patch Cord-5.0 mm

1.Product Construction

1.1 OP (MPO) Hardened Connector End

The hardened end is an OptiTap-type outdoor connector with an MPO interface inside. It consists of a precision MT ferrule holding the twelve fibers, an environmentally sealed housing with an O-ring seal, a threaded (or bayonet) coupling nut for secure engagement with the hardened adapter, and a strain-relief boot. The hardened construction protects the MPO interface from moisture, dust and mechanical impact when exposed outdoors.

MPO Female Connectors	12 Fibers
Note: Female connector need to connect with male connector type.

The standard MPO end follows the MPO interface defined by IEC 61754-7-1 and ANSI/TIA-604-5 (FOCIS 5), with a spring-loaded MT ferrule, guide pins (male) or guide holes (female), a keyed housing and a push–pull latch. It mates with standard MPO adapters and MPO-based transceiver interfaces in protected indoor environments.

1.3 Cable Construction.

Table 3 — Cable cross-section layers

The patch cord uses a 5.0 mm round cable. Twelve 250 µm coated single-mode fibers are protected by aramid yarn strength members and an LSZH outer jacket, providing tensile strength, crush resistance and indoor fire safety.

2.Design Principle

2.1 Parallel-Optics Architecture

The MPO interface is the physical foundation of parallel optical transmission. A single 12-fiber connector carries twelve independent lanes in parallel, each transmitting one optical channel (e.g., 25 G, 50 G or 100 G per lane). This architecture directly matches the MPO-based interfaces of high-speed transceivers such as 100G PSM4, 400G DR4 and 800G DR8, and replaces multiple simplex connectors with one plug for high-density cabling.

2.2 Precision Alignment Mechanism

Fiber-to-fiber alignment is achieved by a passive precision mechanism. Guide pins of the male plug enter the precision guide holes of the female plug and center the two MT ferrules to micron-level accuracy, aligning all twelve fiber cores simultaneously. A compression spring behind the ferrule maintains physical contact between the end faces under controlled force, keeping insertion loss low and stable.

2.3 End-Face Polishing

For single-mode transmission, the ferrule end faces are polished at an 8° angle (APC). The angled end face directs Fresnel back reflections away from the optical path, achieving a return loss of 60 dB or higher. Combined with physical contact under spring load, the design ensures stable optical performance across repeated mating cycles.

2.4 Hardened Sealing and Coupling

The OptiTap (MPO) end is designed for outside-plant exposure: the O-ring-sealed housing and the locking coupling nut provide IP68 protection against rain, humidity and immersion, while the robust housing and strain relief tolerate field handling, pole and facade mounting. This makes the hardened end the weather-proof anchor of the link, with the standard MPO end kept in protected indoor spaces.
