The SMC-9-LCAPC/LCAPCM serves as a single-mode OTDR Launch Cord with a length of 160 meters. Specifically, it features 9 µm LCAPC terminated fibers and robust Metal LC connectors for precise measurements. The cord is color-coded for easy identification and is an essential part for fiber optic testing.

OTDR Launch Cords

Launch cords are long fiber links that allow an Optical Time Domain Reflectometer (OTDR) to properly measure the performance of the first and last connector on a fiber optic link. The reflection from the OTDR port effectively blocks the OTDR from seeing the first part of the cable, so using a launch fiber allows the OTDR to separate the reflection from the port and the first connector in the link. Fluke's launch cords use reference grade fiber and connectors to minimize the impact of the cord on the measurements. When used in sets of three, these cords also support the OptiFiber Pro OTDR’s SmartLoop that tests two fibers in both directions and averages the measurements as required by TIA-568.3-D in seconds - without taking the OTDR to the far end.

Single-Mode (SM) Fiber

Single-mode fiber has a small core that is typically 9µm wide, and a cladding diameter of 125 µm. Single-mode fiber allows for only one type of light mode to be propagated through the fiber. The transmission is therefore laser-focused and efficient, resulting in minimal signal loss and allowing for high-bandwidth applications over long distances. Thanks to this combination of specialized layers, light can travel largely unimpeded throughout the cable network. A receiver then receives the signal at the end of a link. SM fiber is ideal for higher performance, longer distances and data centers where the higher cost of supporting electronics is not an issue.

Angled Physical Contact (APC)

APC fiber end face finishes are color coded green and are found in single mode fiber applications. The end face is slanted 8 degrees. The slight angle reduces back reflections in the core because the reflections are absorbed into the cladding, thereby offering superior return loss performance. Other face finishes are: Flat, PC (Physical Contact), UPC (Ultra Physical Connector).

Rugged Metal LC Connectors

Fluke Networks Test Reference Cords and Launch Fibers with LC connectors feature a unique metal latch design hat offer pull-proof stability (Similar to that of an RJ45 copper connector). The LC latching system uses a multi-piece metal design with a spring located between the latch and connector body. Since this latch is not part of the body and does not flex, the life of the latching mechanism is greatly improved, thereby extending the life of the LC connector and therefore the TRC's and launch cords.

The Metal LC connector is compliant with IEC 61754-20 and TIA-604-10B intermate ability standards. That latch has also been tested for up to 10,000 insertions with no degradation in performance and passes all Telecordia GR-326-CORE durability tests including thermal, humidity, vibration, flex, impact, and salt spray. While the connector itself is the most rugged available, the glass fiber endface is still susceptible to damage, so it’s important to inspect the endface to make sure it’s contaminant-free and to properly clean it if necessary.
