This breakout cable is intended for structured single-mode cabling where one 16-fiber link must be split into two 8-fiber links without using a separate breakout cassette. It is suitable for high-density optical interconnect environments where lower insertion loss, simpler cable management, and direct breakout connectivity are preferred.
The cable uses MTP-16 APC female on one end and 2x MTP-8 APC female on the other, with OS2 9/125μm G.657.A1 bend-insensitive fiber, crossover polarity, 3.0 mm outer diameter, and 0.5 m breakout length. The listed optical performance includes 0.35 dB maximum insertion loss, 0.15 dB typical insertion loss, and return loss of at least 65 dB. The page also lists 1310 nm and 1550 nm operating wavelengths, 10 mm minimum bend radius, and OFNP plenum jacket.
For data center buyers comparing breakout options, the main selection points usually include connector type, polarity, transceiver mapping, insertion loss, fiber type, jacket rating, and whether a direct breakout cable is more suitable than a cassette-based solution. This structure is especially useful when one 800G link needs to be split into two 400G links in a compact cabling environment.

Product Description
This MTP-16 to 2x MTP-8 OS2 breakout cable is a practical choice for high-speed optical links that require direct breakout connectivity without adding cassette hardware. In dense cabling systems, this can help reduce connection points and simplify link structure while keeping fiber mapping clear for transceiver breakout use.
The APC female connector format is suitable for single-mode optical systems that require lower back reflection, while G.657.A1 fiber helps improve routing flexibility in tighter cabling paths. The listed yellow OFNP jacket also matches standard single-mode identification and supports plenum installation requirements.
For projects building 800G to 2x400G links, this cable is suitable when the transceiver and polarity design require direct MTP-16 to dual MTP-8 connectivity. In related single-mode cabling applications, it can also be evaluated alongside single mode fiber patch cord products and G.657.A1 single mode fiber pages when comparing cable structure and routing requirements.
Typical Applications
- 800G to 2x400G breakout links
- High-density single-mode data center cabling
- MTP trunk to breakout interconnection
- Direct breakout alternative to cassette-based links
- Plenum-rated optical cabling environments
How to Choose the Right Breakout Cable
Choose this structure when the link requires one MTP-16 interface to break out into two MTP-8 interfaces.
Choose APC female connectors when the optical system uses single-mode APC mating interfaces and lower back reflection is required.
Confirm crossover polarity before ordering so the cable matches the intended transceiver mapping and link architecture.
Confirm OFNP jacket requirement when the installation includes plenum spaces or building cabling areas that require plenum-rated fiber cable.

FAQ
Which transceivers use MTP-16 to 2x MTP-8 OS2 breakout cable?
This cable is suitable for link structures that require one 16-fiber interface to break out into two 8-fiber interfaces, including 800G QSFP-DD to dual 400G QSFP-DD or OSFP connectivity.
Is MTP-16 to 2x MTP-8 cable used for 800G to 2x400G breakout?
Yes. This structure is designed for 800G to 2x400G optical breakout links where one 16-fiber trunk is divided into two 8-fiber branches.
Should breakout cable or breakout cassette be used for 800G to 400G links?
A breakout cable is generally more suitable when direct connectivity, fewer connection points, and lower link complexity are preferred. A cassette may be more suitable when the cabling design requires modular patching architecture.
What polarity is required for MTP-16 to 2x MTP-8 OS2 breakout cable?
This product uses crossover polarity, so polarity should be confirmed against the intended transceiver mapping and link design before ordering.
Why use APC female connectors for this single-mode breakout cable?
APC female connectors are suitable for single-mode optical systems that require lower back reflection and compatible mating with APC optical interfaces.
Is G.657.A1 fiber important for breakout cable routing?
Yes. G.657.A1 bend-insensitive fiber helps improve routing flexibility in tighter cabling paths and high-density installation environments.
