Product Description
SC UPC Female to Female Fibre SM Fixed Flanged Attenuator

Technical Information:

PUNO's SC/UPC attenuator with push-pull latching mechanism, its keyed, molded housing provide optimum protection. The products are available by both single mode and multimode versions, single mode SC have two types, one is SC UPC and the other is SC APC, multimode only has SC UPC connectors. They fit typical 1310nm and 1550nm single mode fiber applications. Attenuation range is from 1dB to 30dB.

Features:

Fully compatible with SC fiber optic connectors;
Precise attenuation values Industry standard attenuation levels;
Low PDL and insertion loss;
Precision polishing for reduced back reflection Highly;
Reliable Physical Contact Connectors;
Compartmentalized case provides safe component storage and simple organization;
Small, durable case for easy portability;
RoHS compliant.

Application:

Fiber sensors;
CATV;
Test Equipment;
Fiber-to-the-home;
Telecommunications.

Does Multimode or Single-mode Systems need attenuators?

Generally, multimode systems do not need attenuators. Multimode sources, even VCSELs, rarely have enough power output to saturate receivers. Single-mode systems, especially short links, often have too much power and need attenuators. For a single-mode applications, especially analog CATV systems, the most important specification, after the correct loss value, is return loss or reflection! Many types of attenuators (especially gap loss types) suffer from high reflection, so they can adversely affect transmitters just like highly reflective connectors.

Choose a type of attenuator with good reflectance specifications and always install the attenuator ( X in the drawing) as shown at the receiver end of the link. This is because it's more convenient to test the receiver power before and after attenuation or while adjusting it with your power meter at the receiver, plus any reflectance will be attenuated on its path back to the source.

Test the system power with the transmitter turned on and the attenuator installed at the receiver using a fiber optic power meter set to the system operating wavelength. Check to see the power is within the specified range for the receiver. If the appropriate attenuator is not available, simply coil some patchcord around a pencil while measuring power with your fiber optic power meter, adding turns until the power is in the right range. Tape the coil and your system should work. This type of attenuator has no reflectance and is very low cost! The fiber/cable manufacturers may worry about the relaibility of a cable subjected to such a small bend radius. You should probably replace it with another type of attenuator at some point, however.
