The SRC-9-SCLC-M serves as a single-mode test reference cord (TRC) with a length of 2 meters. It features 9 µm SC, LC terminated fibers and Fluke's robust Metal LC connector for precise measurements. The cord is color-coded for easy identification and is an essential part for fiber optic testing.

Test Reference Cords (TRC)

TRCs, terminated with reference grade connectors, are used for certifying cabling systems to ANSI/TIA, ISO/IEC, and IEEE standards, with multimode connectors having a mated loss of ≤ 0.10 dB and singlemode connectors found in ISO/IEC 14763-3 having a mated loss of ≤ 0.20 dB. They are essential when installing low loss connectors with a loss of ≤ 0.15 dB, as using a connector with a higher loss for testing could yield pessimistic results and potentially fail a perfectly good link. TRCs also ensure consistent and predictable results, addressing a common complaint among installers during system certification.

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. SM fiber is ideal for higher performance, longer distances and data centers where the higher cost of supporting electronics is not an issue.

SC - Common 2.5mm Connectors

SC, FC and ST fiber optic connectors all feature a 2.5mm ferrule size and can therefore be mixed and matched using special hybrid adapters. Developed by Nippon Telegraph and Telephone (NTT), the SC connector is easily recognized by its square shape. It features a snap-in design that mates using a push-pull action with a spring-loaded ferrule. Available as simplex or duplex, the SC is covered by TIA-604-3 (FOCIS-3), and due to its excellent insertion loss performance and fast deployment, it dominated as the connector of choice well into the 1990s. It still likely remains the second most common fiber connector type for simplex and duplex applications.

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 intermateability 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.
