How do SC/UPC and SC/APC patch cords differ - can they be mixed?

UPC and APC are different types of connector end-face polishing. The SC connectors are physically identical, but APC has an angled bevel and a green housing. They cannot be mixed: connecting UPC with an APC adapter will result in huge signal loss. When working with GPON networks, use exclusively APC.

Which patch cord should I choose for connecting an SFP transceiver in a switch?

Most SFP transceivers use an LC Duplex connector. The fiber type (SM or MM) depends on the transceiver type: single-mode SFPs work only with single-mode cable, multimode ones - with multimode. Check the transceiver marking before ordering a patch cord.

How much does an optical cross-connect and its installation cost in Tashkent?

The cost depends on the capacity (number of ports), the type of adapters and the completeness. A fully assembled cross-connect for 8 LC Duplex ports in a 19-inch design is a ready-made solution for rack mounting. For a calculation of the full cost including installation and splicing, request a commercial proposal from SAT Solutions managers.

Can multimode OM4 patch cords be used for new server installations?

OM4 (50/125 microns) supports 40G and 100G speeds over distances up to 150 meters and is the current standard for data centers. For connections with MPO connectors (bundles of 12 fibers), OM4 is preferable thanks to its low attenuation and wide bandwidth.

Do you carry out the supply and installation of optics outside Tashkent?

Yes, SAT Solutions works throughout Uzbekistan. Delivery is carried out by transport companies or our own transport, and installation crews travel to the regions. Check the terms and deadlines when placing an order.

Fiber & accessories — guide & FAQ

Optics and accessories are a category of passive network equipment without which it is impossible to build modern fiber-optic infrastructure. It includes patch cords, mounting cords, adapters, optical cross-connects and auxiliary mounting units. It is precisely these components that provide the physical connection of fiber-optic lines: from backbone cables to the terminal switching equipment. Buying optics and accessories in Tashkent today is easier than a few years ago - the market is saturated, however, the correct selection of components still requires engineering expertise.

The category covers a wide range of products: single-mode and multimode patch cords with LC, SC, FC and MPO connectors, adapters for cross-connect panels, optical cabinets (ShKOS) in a 19-inch design, adapter strips and mounting fixtures. Each element performs a strictly defined function in the optical signal transmission path, and the replacement of even a single incompatible component can lead to a loss of signal level or a complete break in the line. The choice of equipment for Uzbekistan is complicated by the fact that facilities differ in scale: from small offices to large industrial enterprises and government agencies.

The key parameter when forming an order is the fiber type (single-mode SM or multimode MM) and the connector type (LC, SC, FC, MPO). An error in these parameters makes the component unusable. Therefore, before purchasing, it is important to have design documentation or at least the specification of the existing line. The SAT Solutions catalog features 242 items, which makes it possible to select a complete set of accessories for most standard and non-standard configurations.

How to choose

Fiber type: single-mode (SM, 9/125 microns) is used over long distances and in backbone lines; multimode (MM, 50/125 or 62.5/125 microns) - inside buildings and on short sections up to several hundred meters. They cannot be mixed up: the equipment simply will not work.
Connector type: LC Duplex - the standard for active equipment (switches, transceivers); SC - common in telecommunication nodes and passive optical networks; FC - used in measuring equipment and some industrial systems; MPO - for high-density server installations with bundles of 8, 12 or 24 fibers.
End-face polishing type: UPC (Ultra Physical Contact) gives return loss no worse than 50 dB and is suitable for most applications; APC (Angled Physical Contact) with an 8-degree angled polish provides return loss over 60 dB and is mandatory in passive optical networks PON (GPON/EPON).
