Master LC Patchcord
We offer an extensive range of pre-terminated cable assemblies that are 100% tested to ensure conformance with your specifications. These assemblies are used for measuring and manufacturing of fiber optic components and optical network testing.
The Master patchcord is equipped with a Master connector according to the specifications below. The master connector is marked and specified with its Serial Number, which ensures traceability of transmission and geometrical parameters. The second connector is a standard type. For the hybrid patchcord version different types of master and standard connector types are also available.

Note: 1) RL ≥ 58 dB (UPC) and RL ≥ 78 dB (APC) measured with low coherence reflectometry (IEC 61300-3-6 method 3 OLCR)
2) Valid over 1260-1650 nm wavelength range and within operation temperature range -30 to +70°C, tested according to IEC 61300-3-12
3) AAA – second connector types according to relevant datasheets
4) Standard Master patchcord length – 2 m, other on demand
However in case of longer Master patchcord Rayleigh scattering in glass produces small levels of back reflections. Because of backscatter, a link will produce intrinsic reflections which are dependent on the length.
