Standard UPC matching with the secure handling of an FC body
This FC/UPC fixed fiber optic attenuator is used to reduce optical signal power in single-mode links while keeping the connector format consistent with FC/UPC equipment, patch cords, and test ports.
Compared with the FC/APC version, this page should not lead with angled-polish back-reflection language. The stronger buyer angle is standard UPC compatibility, threaded FC coupling, and practical fixed attenuation values for link adjustment.
The supplied files show a 3 dB sample in the main image and additional named samples from 4 dB to 8 dB, which gives the page a real SKU-evidence base before final attenuation options are confirmed from the datasheet.
Why this FC/UPC page is different from FC/APC
Both products use an FC-style threaded metal body, but the polish requirement is different. FC/UPC is the ultra physical-contact style, while FC/APC is the angled-polish style used when lower back reflection is the main concern.
The supplied FC/UPC photos use white and translucent protective caps rather than green APC coding. This visual difference should be kept in the final product gallery and page copy.
For buyers, the practical question is simple: does the link use FC/UPC ports, and what fixed attenuation value is needed to bring the receiver-side optical power into range?
Built for repeatable FC/UPC optical power reduction
Threaded FC coupling
The knurled metal sleeve and FC-style threaded design help the attenuator stay firmly mated during handling, testing, or cabinet maintenance.
01
UPC connector matching
The page is written for FC/UPC systems where the buyer needs a matching physical-contact connector rather than an APC angled-polish option.
02
Visible mid-range dB samples
The supplied images and filenames show 3 dB, 4 dB, 5 dB, 6 dB, 7 dB, and 8 dB examples, giving the page a more specific product-range story.
03
Compact male-female body
The inline male-female format lets users add a fixed attenuation point without changing the surrounding FC/UPC cable route.

Confirmed local details and safe external context
| Item | Page Value | Evidence Level |
|---|---|---|
| Product type | Male-female fixed fiber optic attenuator | Confirmed by local folder, photos, and product naming |
| Connector type | FC | Confirmed by FC UPC folder and threaded FC-style product appearance |
| Polish type | UPC | Confirmed by local folder name and non-APC visual presentation |
| Fiber type | Single-mode positioning | Supported by local datasheet filename including SM |
| Visible attenuation samples | 3 dB shown in photo; 4 / 5 / 6 / 7 / 8 dB shown in local filenames | Confirmed by local images and file inventory |
| Common FC/UPC attenuator range | External references show FC/UPC fixed attenuators commonly offered across broader 1-25 dB or 1-30 dB ranges | Use as industry context, not final FOCC SKU claim |
| Operating wavelength | Common references include 1310 / 1550 nm and wider single-mode operating bands | Confirm final FOCC value from datasheet |
| UPC return-loss context | External FC/UPC references commonly publish UPC return-loss values around 45-50 dB or higher, depending on product grade | Use only as reference context; confirm FOCC value before publishing |
Where FC/UPC fixed attenuators fit best
Test equipment links
FC connectors are often seen in test setups, making this product useful for controlled attenuation during lab or field checks.
Receiver input adjustment
The attenuator can be specified when a receiver-side signal is above the desired power range and needs fixed reduction.
CATV and communication systems
External datasheets for similar male-female attenuators list CATV, optical communication, access networks, and point-to-point systems as typical use cases.
Maintenance inventory
The clear dB label and compact FC body make the product practical for distributors and installers who stock multiple attenuation values.
How a buyer should select this FC/UPC attenuator
- Confirm the connector is FC/UPC. If the link is FC/APC, use the FC/APC page instead.
- Check the target receiver power. Choose the fixed dB value from the link budget, test result, or equipment input range.
- Confirm wavelength and test report needs. Use 1310 / 1550 nm or other required windows only after the order requirement is clear.
- Decide sample, stock, or project quantity. The visible 3-8 dB set is especially suitable for multi-value service inventory discussions.
Common questions for FC/UPC attenuator sourcing
Is FC/UPC interchangeable with FC/APC?
No. The connector family is both FC, but UPC and APC polish types should be matched correctly. Mixing UPC and APC can cause poor contact and unstable optical performance.
Which attenuation values are shown in the supplied files?
The supplied FC/UPC materials show a 3 dB product image and named files for 4 dB, 5 dB, 6 dB, 7 dB, and 8 dB. The final orderable range should be confirmed with FOCC's datasheet and stock list.
What is this product used for?
It is used to reduce optical power to a stable target level, protect receiver inputs, support test-equipment calibration, and balance optical links without changing the original fiber route.
Can this page publish return loss and tolerance values?
External FC/UPC references provide useful benchmark ranges, but FOCC's exact return loss, tolerance, temperature range, and wavelength window should be confirmed from the official datasheet before publishing as guaranteed specifications.
External references used without copying competitor specifications
The FC/UPC page uses FOCC local images as the primary product evidence. External manufacturer and technical sources are used only to support product-family context, connector-polish education, and sourcing logic.
