Fiber Optical Attenuator

Quantity

Fiber Optic Attenuator is a component installed in a fiber optic transmission system that reduces the power in the optical signal. It is often used to limit the optical power received by the photo detector to within the limits of the optical receiver. Sopto can provide female to male (plug type), Bulkhead-fixed value attenuator, in-line attenuator and variable attenuators.Feature● Low back reflection and Low PDL● High precision attenuation value● Precision control of attenuation range● Wide attenuation range● Precision ceramic ferrule● FC, SC, ST, LC … optional● PC,UPC and APC available● Plastic or metal housing materialItem | Unit | ParameterOperating Wavelength | Nm | 1310/1550Attenuation Range | dB | 1-10dB(1dB step), 15, 20, 25, 30dBReturn Loss | dB | PC:≥50 UPC: ≥55 APC: ≥60Attenuation Tolerance | dB | ≤1.0 (11-30dB)Working Temperature | ℃ | -25℃~+75℃Storage Temperature | ℃ | -40℃~+ 85℃Applications● Optical line distributing frame● Fiber-optical network system● Hi-speed fiber-optical transmission system● Dense Wavelength Division Multiplex (DWDM) system● Optical add-drop multiplexers (OADM)Related Articles● SC Fast Connector Assembly Instruction● The fiber optic connector common classification and characteristicsOrdering InformationOrdering Info. for Attenuator | Ordering Info. for AttenuatorPart Number： SPAT- FC F- FC F- U- 5 F M 1 2 3 4 5 6 7 8 Product Description：Attenuator FC Female/FC Female UPC 5DB SM Fixed Value Metal Shell | Part Number： SPAT- FC F- FC F- U- 5 F M 1 2 3 4 5 6 7 8 Product Description：Attenuator FC Female/FC Female UPC 5DB SM Fixed Value Metal Shell1 - Connector A | LC SC FC ST etc2 - Connector A Type | F:Female ; M:Male3 – Connector B | LC SC FC ST etc4 – Connector B Type | F:Female ; M:Male5 - Endface | U：UPC polish; P：PC polish; A：APC polish6 - Attenuation Value | 1:1DB ; 3:3DB; 5:5DB; etc 30;1-30DB7 - Variable | F:Fixed value; V:Variable; I:Inline Fixed ; S: Inline Variable8 -Shell Material | P:Plastic; PM:Half Plastic Half Metal; M;Metal9 -Structure 1 | E:with Ears; Null:without Ears10 - Structure 2 | S:with Spring strip; Null:without Spring stripDatasheetshttps://www.sopto.com.cn/upload/201906/03/201906031409027306.pdf
