Compared to conventional fiber optic cables, 9/125 m OS2 single mode bent insensitive fiber optic cables decay less when bent or twisted, which makes the installation and maintenance of fiber optic cables more efficient.

It also saves more space for data centers, enterprise networks, telecommunications rooms, farms, cloud storage networks, and high-density cabling wherever fiber jumpers are required. This 9/125 OS2 single-mode fiber optic cable is ideal for connecting 1G/10G/40G/100G/400G Ethernet connections. It can transmit up to 10 km of data at 1310nm or up to 40km at 1550nm.

G.652D is the fiber-optic fiber model in fiber optic cable, representing the non-dispersion displacement single-mode fiber, is currently the most widely used single-mode fiber. Commercially launched in 1983, its scattered wavelength at 1310nm, at 1550nm at the minimum attenuation, but there is a larger positive dispersion, about 8ps (nm/km), the working wavelength can be selected 1310nm, can also choose 1550nm.

This fiber is the most widely used fiber, most of the fiber has been laid, fiber optic cable is most of this kind of fiber. In the late 1970s, attempts were made to replace light-emitting diode light sources with developed long-life semiconductor lasers to obtain longer communication distances and greater communication capacity, but pattern noise occurs when lasers are transmitted in multimode optical fibers. In order to overcome the mode noise, in 1980 successfully developed a single-mode fiber (non-dispersive displacement single-mode fiber), referred to as standard single-mode fiber, which ITU-T recommends as G.652 fiber. Because the design idea of single-mode fiber is to transmit only one mode, there is no mode noise that occurs when transmission occurs in multimode fiber. Therefore, in the mid-1980s, 140Mbit/s optical fiber communication system consisting of laser light source and standard single-mode fiber, in which the relay distance and transmission capacity far exceeded the transmission system of coaxial cable, so that the optical fiber communication system gradually replaced the copper cable communication, becoming the main communication mode adopted in the telecommunications industry.

The G.657 access network with bending attenuation insensitive single-mode fiber optic cable characteristics” is the standard that ITU-T issued in November 2006.

G.657 Fiber is the latest fiber variety developed based on G.652 fiber to achieve the goal of fiber-to-the-home. The main characteristic of this type of fiber is its excellent bending resistance, which achieves a bending radius of 1/4 to 1/2 of the conventional G.652 fiber. G.657 fiber sub-A, B two subcategories, in which G.657A fiber performance and its application environment and G.652D type fiber similar, can be in the 1260 to 1625nm wide wavelength range (i.e. O, E, S, C, L5 working bands) work The G.657B fiber mainly works at 1310nm, 1550nm and 1625nm 3 wavelength windows, which is more suitable for the transmission of FTTH information, installation in the interior or building and other narrow places.

OS2 fiber jumper has a single-mode simplex fiber optic jumper and single-mode duplex fiber jumper two kinds, they are mainly different in the fiber level, wherein the single-mode duplex fiber jumper application range is wider, can be applied to data center, CATV, FTTH, WDM/DWDM, passive optical network and other fields of high-density cabling environment. Os2 single-mode duplex fiber jumper’s outer sheath is mostly yellow, wavelength and maximum attenuation values of 1550nm and 0.4dB/km, it allows data to be transmitted in both directions at the same time, and requires both the sending and receiving devices to have independent reception and transmission capabilities.

Os2 single-mode duplex jumpers provide better performance and are more cost-effective in long-distance data transmission than regular multimode fiber jumpers. OS2 single-mode duplex fiber jumper according to cable material can be divided into PVC (OFNR) OS2 single-mode duplex fiber jumper, LSZH OS2 single-mode duplex fiber jumper and OFNP OS2 single-mode duplex fiber jumper these three types, according to grinding method can be divided into UPC/UPC.

OS2 single-mode duplex fiber jumper has UPC and APC connector types. In addition, the OS2 single-mode duplex fiber jumper with LC connector can be compatible with the SFP optical module, the SFP (BIDI SFP plus) optical module, and the XFP optical module, while the OS2 single-mode duplex fiber jumper with SC connector can be compatible with the BIDI SFP optical module, GBIC optical module, The X2 module and the XENPAK light module are compatible.

All OS2 single-mode duplex fiber jumpers are made of RoHS-compliant G652D fiber and are rigorously tested at the factory to ensure that the end surface is spotless, and that the insertion and echo losses are in line with international telecommunications standards. In addition, Huihongfiber offers a full range of fiber jumper customization services such as fiber connection head, length, color, fiber grade, specifications, materials, packaging, etc.
