12F ODVA(mpo)-ODVA(mpo) 5.0mm cable New one
This specification covers a 12-fiber single-mode (SM) patch cord terminated with an ODVA (MPO) multi-fiber push-on connector at each end and assembled with a 5.0mm OD Double sheath round cable. The assembly integrates twelve OS2 single-mode fibers into one precision MT ferrule per connector, providing a compact, high-density and field-friendly interconnect for parallel optical transmission.
The product is designed for high-speed, high-density optical links in data center, AI and HPC clusters, campus and metro networks, as well as outdoor and industrial applications where the ruggedized ODVA connector system is adopted.
Please note 24F is available too. Just cable&connector is different.

3. Product Construction
3.1 Connector Assembly
Each end of the patch cord is terminated with an ODVA (MPO) plug. The plug consists of a precision-molded MT ferrule that holds the twelve fibers in a single row at a 0.25 mm fiber pitch, two precision guide pins (or guide holes for the female version) with a 4.6 mm pin pitch, a spring-loaded ferrule mechanism, a molded housing, and a strain-relief boot. The spring-loaded float of the ferrule ensures physical contact between the two end faces after mating, which is essential for stable optical performance.
| Parameter | Specification |
| Connector interface | ODVA (MPO), 12-fiber |
| Ferrule | MT, precision-molded, single row of 12 fibers |
| Fiber pitch | 0.25 mm |
| Guide pin pitch / pin diameter | 4.6 mm / Ø0.7 mm |
| Gender | Male (with pins) / Female (without pins) |
| End-face polish | APC 8° (standard); UPC optional |
3.2 Cable Construction
The patch cord uses a 5.0 mm double Sheath round cable. Twelve 250 µm coated single-mode fibers are positioned in the center, surrounded by aramid yarn strength members and protected by an LSZH outer jacket. The aramid yarn provides tensile strength and crush resistance, while the LSZH jacket offers flame retardance, low smoke and low toxicity emission in indoor environments.

4. Application Scenarios
4.1 Data Center and AI / HPC Networks
The 12-fiber SM patch cord is the standard building block for parallel single-mode optics in modern data centers: 100G PSM4, 400G DR4 and 800G DR8 links using QSFP28, QSFP-DD or OSFP transceivers with MPO interfaces. It is used for switch-to-switch, switch-to-server and compute-fabric patching in spine-leaf and AI/HPC clusters where high density and low latency matter.
4.2 High-Density Patching and Cabling
With twelve fibers in a single connector, the patch cord dramatically reduces port footprint and cable count in ODFs, fiber distribution frames, patch panels and pre-terminated trunk systems, simplifying cable management, airflow and moves-adds-changes (MAC) operations in constrained rack space.
4.3 Campus, Metro and Telecom Networks
Single-mode transmission supports long-reach links across campus backbones, metro rings and central-office patching at 10G/25G/100G and beyond, providing the reach and scalability that multimode solutions cannot achieve.
4.4 Outdoor and Industrial Applications
Where the ODVA connector system is specified, the ruggedized ODVA housing protects the MPO interface for outdoor, FTTA/5G fronthaul, industrial Ethernet and other harsh-environment deployments requiring reliable, weather-protected multi-fiber interconnection.
