Fiber is divided into two categories:
Fiber Optic Jumper Features:
Single-mode fiber: The general fiber jumper is indicated by yellow, the
connector and the protective cover are blue; the transmission distance
Multi-mode fiber: The general fiber jumpers are indicated by orange, and
some are gray, and the connectors and protections are beige or black;
the transmission distance is shorter.
Use of fiber attention!
Fiber optic jumper at both ends of the optical transceiver transceiver
wavelength must be consistent, that is, both ends of the fiber must be
the same wavelength of the optical module, a simple distinction is the
color of the optical module to be consistent. R> In general,
shortwave optical modules use multimode fiber (orange fiber), and
longwave optical modules use single mode fiber (yellow fiber) to ensure
the accuracy of data transmission.
Do not over-bend and circulate the fiber in use, which will increase the attenuation of the light in the transmission process.
Fiber optic jumper must be used after the protective cover to protect
the fiber optic joints, dust and oil will damage the coupling of the
fiber. (ADSS cable)
1. The use of a small concentricity error and the hole diameter of the
high-precision ceramic ferrule, to provide additional insertion loss and
return loss, to avoid the decline in transmission performance and
optical transceiver damage.
2. The use of advanced grinding technology and grinding equipment to
ensure that the center of the optical fiber grinding offset, optical
fiber sag and the radius of the ceramic surface radius of the technical
parameters are in line with the provisions of the standard.
3. In order to ensure the long-term use of the connector, the company
not only decapsulates the joint and back reflection test, but also uses
the precision interferometer to test the surface of the joint scratches
or flaws, measured FC, ST, SC, LC and MU type Curvature half by,
grinding offset, fiber depression and protrusion to ensure joint
4.100% optical full detection, each jumper are guaranteed to have good grinding quality and excellent performance indicators.
5. According to the needs of customers configured for single-core,
dual-core or multi-core and other different core types. Fiber products
and PVC and LSOH different fire rating, to provide design flexibility.
6. Insertion loss is small, return loss, interchangeability, repeat the excellent performance of plug, easy to use.
7. In line with ANSI / TIA / EIA and ISO / IEC for durability, moisture,
coupling stress, fiber tensile force and wet, extreme temperature, plug
force and cable tensile stress, impact and vibration and other harsh
environmental adaptability Claim.
8. Environmental stability, environmental testing by Telcordia standard.

"We are expecting a very full review of aluminum alloy profilethe impacts of this project.S., is known for its stunning scenery, access to the outdoors and eclectic mix of aging hippies, students and other residents. He said the company plans to follow the highest environmental standards."Two other projects are proposed in Oregon at Coos Bay and St.
Helens., before being loaded onto ships bound for Asia. coal producers has been running TV and newspaper ads to tout jobs, tax revenues and other economic benefits. Only some ports will be built, they say, and each has different circumstances."Several union leaders and some lawmakers say the region can't afford to turn down well-paying jobs. We need jobs," said Mike Elliott, chairman of the state's Brotherhood of Locomotive Engineers and Trainmen. But Bellingham resident Lynn Berman and others fear the increase in coal shipments -- about nine mile-long trains a day -- could threaten fisheries, create health problems and foul the area's natural resources. We're seen as a region that leads with innovation," said Kimberly Larson, with the Power Past Coal campaign.
This always has been a major fishing and harvesting site for our fishermen. "This site has been intended for this purpose," said Cole, a former Whatcom County Councilman. coal to Asia. Another in Grays Harbor County, Wash. "We're not saying yes and we're not saying no either.. Hearings in Seattle, Vancouver and Spokane are also expected to draw crowds.With so much at stake, critics and supporters have intensified their pitches in recent weeks, running TV and radio spots, doorbelling homes and turning to phone banks and social media to rally support for their side.
