Barnfind goal is to offer the most flexible and affordable infrastructure platform in the Video Business with the greenest technologies available at any time. Barnfind platform based on the universal SFP (Small Form Factor Pluggable) offerings. The equipment accept all kinds of SFP manufacturers following the MSA standard. Most competitors do non-standard pin layout and are extremely expensive.
The article describes a series of questions that allow the customer to choose optical cable of optimum design, to distinguish marketing gimmicks of suppliers from objective presentation of technical characteristics. The problems arising because of imperfect design of OC and its components are analyzed. We consider the well-known problem of fibers retracting in overhead optical cables of UT type. There are some tips on how to fix it.
The article details the features of optical measurements for networks PON: kinds of measurements, factors affecting the quality of transmission, measurement schedules and measurable parameters. The problems encountered at such measurements and their solutions are discussed. The necessary test equipment and its parameters important for application in PON are enlisted.
Sequence of operations for installation of bandage tape and tools required for that are as follows.
The article considers the equipment used to connect optical fibers by splicing, describes its operation principles, methods of optical fibers aligning during splicing, as well as characteristics of some models of splicing machines and cleavers.
Designation of the optical cable FinMark consists of several groups of letters and digits meaning the following;
With the growth of application range for optical fibers in different areas of telecommunication sphere, the fibers themselves were impoved gaining new parameters, optimized for different tasks. At the present time several types of optical fibers are used, their properties are specified by recommendations of International Telecommunications Union.
Here you can see visual connection diagrams for terminal and input-output (Add / Drop) CWDM multiplexers at different network topologies (bus, wye), single and bi-fiber connection.
The article considers the main types of instrumentation required for construction and operation of the optical cable networks. Their operating principles, main measurement schemes and parameters of devices are described. Helpful advice is given for entry-level meter-men. There are references to specific models of devices of various types.
Detailed, step by step optical connector quick assembly guide.
Provision of full “triple-play” service has nearly becomeпарогполо a standard practice for broadband operators. Traditional broadcast networks of digital cable TV allow the arrangement of data transfer and telephony with use of DOCSIS technology. However, due to limited frequency resource, there exists a problem of ensuring the high exchange rate during extension of subscriber base. Further upgrade of such utilities – in particular, transition to new DOCSIS 3.0 standard – requires the substantial financial investments.
