See tables 1 to 5 of the Standard Tables for other standard fiber sizes Fiber Patchcord Inline Fixed Attenuator: Connector Code: 3S = Super NTT-FC/PC 3U = Ultra NTT-FC/PC 3A = Angled NTT-FC/PC 8 = AT&T-ST SC = SC SCA = Angled SC See Table 6 of the Standard Tables data sheet for other connectors Wavelength: Specify in nanometers (Example: 1550 for 1550nm) Fiber Core/Cladding size in microns Example: 9/125 for 1300/1550nm SMF. See tables 1 to 5 of the Standard Tables for other standard fiber sizes Fiber Jacket Type: 1 = 900 micron OD hytrel jacket 3 = 3mm OD Kevlar reinforced PVC cable See Table 7 of the Standard Tables data sheet for other jacket sizes PFA-XY-W-a/b-JD-L-F-N Patchcord Attenuation: 5 for 5dB 10 for 10dB 15 for 15dB 20 for 20dB 25 for 25dB Fiber type: M = Multimode S = Singlemode P = Polarization maintaining Fiber length, in meters, on each side of the device. Example: To order 1 meter of fiber at the input and 7 meters at the output, replace " L" with 1,7 Example: A 20dB fixed attenuator is required for 9/125 singlemode fiber, with an operating wavelength of 1300nm. The input connector is to be a female receptacle for angled FC connectors, while the output connector is a male SC connector. OZ part number: FA-300-3ASC-1300/1550-9/125-S-20.
