SC/APC to SC/APC SX SM Coupler
SC/APC to SC/APC Green Adapter with Flange, Simplex Singlemode 9/125 Female to Female Fiber Optic Coupler

This SC/APC female to SC/APC female Singlemode 9/125 Fiber Optic Adapter, is a mating sleeve that is designed for connecting together SC male connectors when we need to connect together fiber optic cables with this type of connectors.

SC/APC to SC/APC Adapter Singlemode Simplex Fiber Optic Coupler Female to Female with low 0.2dB insertion loss. The combination of a ceramic / phosphor bronze alignment sleeves and a precision mould polymer housing provides consistent long-term mechanical and optical performance.

Fiber optic adapter, sometimes also called coupler, is a small device designed to terminate or link the fiber optic cables or fiber optic connectors between two fiber optic lines. By linking two connectors precisely, fiber optic adapters allow the light sources to be transmitted at most and lower the loss as much as possible. At the same time, fiber optic adapters have the merits of low insertion loss, good interchangeability and reproducibility. it is widely applied in cable television network, LAN & WAN, fiber optic access network and video transmission.

The fiber optic adapter or coupler is designed to mate two ends of the fiber optic cable with high precision. The adapter uses a simple design: the ends of two separate fiber optic cables with fiber optic connectors fit into two slots opposite each other. The slots are comprised of a polymer/metal outer body and inner assembly fitted with a precision alignment mechanism to precisely align the two ends so that there is minimal to signal loss. It provides a great solution to meet the growing demand for small form factor, high-density fiber optic connectivity.

This SC Simplex Adapter allows you to patch together SC connectors or SC fiber patch cables quickly. The SC coupler is particularly suitable to connect two simplex SCs for a fast, precisely, quality field connection. The SC APC adapters feature ceramic / phosphor bronze alignment sleeves which provide precision mating for singlemode applications.

Additional useful information:
Adapters are designed for multimode or singlemode cables. The singlemode adapters offer more precise alignment of the tips of the connectors (ferrules). It is ok to use singlemode adapters to connect multimode cables, but you should not use multimode adapters to connect singlemode cables. This can cause misalignment of the small singlemode fibers and loss of signal strength (attenuation).
When connecting two multimode fibers, you should always make sure they are the same core diameter (50/125 or 62.5/125). A mismatch here will cause attenuation in one direction (where the larger fiber is transmitting light into the smaller fiber).
Fiber optic adapters are typically connecting cables with similar connectors (SC to SC, LC to LC, etc.). Some adapters, called “hybrid”, accept different types of connectors (ST to SC, LC to SC, etc.). When the connectors have differing ferrule sizes (1.25mm to 2.5mm), as found in LC to SC adapters, the adapters are significantly more expensive because of a more complicated design/manufacturing process.
Most adapters are female on both ends, to connect two cables. Some are male-female, which typically plug into a port on a piece of equipment. This then allows the port to accept a different connector than for which it was originally designed. We discourage this use because we find the adapter extending from the equipment is subject to being bumped and breaking. Also, if not properly routed, the weight of the cable and connector hanging from the adapter may cause some misalignment and a degraded signal.
Extending Fiber Connection with Adapters
With high-precision components and tool-less design, the adapters allow two devices to communicate from a distance through a direct connection with the fiber optic line.

SC/APC to SC/APC Green Adapter

Color-coded Adapters Simplify Fiber Management
The adapter housing colors follow the TIA/EIA-568-C.3 suggested color identification scheme, effectively helping technicians make better cable management and reduce human errors. They come is 5 color options to indicate the fiber type as following: Single Mode adapters come in Blue for UPC or Green for APC and Multi Mode adapters come in Beige for OM1/OM2, Aqua for OM3 and Violet for OM4.
*Note: Adapters may be specially ordered in other colors depending on the color management needed, e.g all adapters used might be LC/APC but ordered in different colors for better management.

OPDCS0009 can be purchased in the standard Green color or the Optional Blue color.

It is used to connect two fiber optic cables with SC (Square Connector) APC (Angled Physical Contact) connectors. It can be used with fibre optic patchcords, which send high-speed data through a network. The adapter is a part of optical path, it guarantees stability of transmission parameters, and high quality ceramic ferrule, that is polished at an 8-degree angle, assures lower return loss. Openable clips ensure easy assembly and disassembly. Cable Simplex which has application in this adapter, is used in cable ducts, cubicles and pipes with low mechanical pressure.

SC connectors are mostly used in telecommunication. It is also used in active equipment such as video converters and media. It ensures easy, quick connection and it is resistant for connection defects. The shape of connector assures easy and stable assembly. Beside usage in telecommunication, SC connector is also used in LAN, WAN and CATV networks, measuring techniques and on the railway.
