✅SC/UPC Fiber Optic Attenuato: SC/UPC Male to SC/UPC Female, 10dB, Singlemode fixed, Ceramic Core material, 2 Pack. Provide SC adapters to ensure the connection between fiber patch cable..
✅Low Insert-loss & High Return-loss: Polarization dependent loss ≤0.2dB and Return Loss: ≥ 50dB. Using an attenuator to prevent over saturating an optical receiver when the optical power is too high and ensures low bit error rates preventing damage to receiving fiber optic equipment..
✅Good Repeatability & Intercalation: Widely used in Optical Fiber Distribution Frame, Optical Communication Network, Optical Fiber Broadband Access Network, Optical Fiber CATV, Optical Fiber Testers, FLAN, the performance is stable and reliable..
✅Feature: Light weight, small volume, high accuracy, good stability and convenient operation..
✅Attenuator Application: Optical attenuator is a passive device used to reduce the power level of an optical signal. It is generally used in single-mode long-haul applications to prevent optical overload at the receiver..

Measuring power range -75 ~ +16 dBm (external RF attenuator can be extended to 100dBm).

The OB-6 is a once-in-a-lifetime collaboration between two of the most influential synth designers in history — Dave Smith and Tom Oberheim.
It’s an all-analog, 6-voice poly synth with voltage-controlled oscillators, a state-variable filter, and voltage-controlled amplifiers, inspired by Tom’s original SEM design — the bedrock of his legendary 4-voice and 8-voice synthesizers.
Manufactured and sold by Dave Smith Instruments, the OB-6 features six discrete analog voices with two oscillators (plus sub oscillator) per voice, continuously variable waveshapes with triangle, sawtooth, and variable-width pulse waves, X-mod with 2 sources and 5 destination, a 64-step polyphonic step sequencer, dual digital effects that include faithful recreations of Tom’s acclaimed phase shifter and ring modulator, a full-featured arpeggiator, and a powerful, in-your-face, sonic signatur....
This analog powerhouse is packed into a four-octave, semi-weighted keyboard with velocity and channel aftertouch, making it perfect for stage or studio.
