How To Clean The Fiber Optic Connector

Fiber optic cleaning is one of the most important thing in the process of fiber optic system maintenance, which is required to keep quality connections between fiber optic equipment. As we know, the fiber optic connector consists of fiber optic plug and the adapter. The ends of the fiber optic cables are held in the core of ferrule in the plug. Keeping the fiber end face and ferrule absolutely clean is very essential, since any particles such as dust, oil or lint on the end face of the fiber, it will disrupt the light transmission trough the fiber and lead to the completeness of optical signals for the component or the entire system.
For proper performance of the SC fiber optic cable, you must keep the SC connector clean and free of dust. Small micro-deposit of oil and dust in the canal of the connector could cause loss of light, reducing signal power and possible causing intermittent problems with the optical connections. Below picture show the part of the end face of an unclean and clean ferrule of SC connectors.
What should be followed before the fiber optic cleaning
1.Before cleaning the fiber optic connectors, make sure to disconnect the fiber optic cables from both ends and then turn off any laser source.
2. Do not allow the end of the fiber optic cable to make contact with any surface including your fingers.
3.Never to bend the fiber cable, which will in turn cause internal breaks along the fiber and cause poor performance or instability.
4.Use the finger cots or powder free surgical gloves to handle the fiber optic cables.
5.Use fresh spectroscopic grade Methanol or Isopropyl Alcohol as the only cleaning solvent.
6. In the daily connection work, a connector housing should be used when plugging or unplugging a fiber. A protective cap should be used to cover the unplugged fiber connectors.
7. In the process of the fiber optic cleaning, the end face of the connector should never be touched and also the clean area of a tissue of swab should not be touched or reused.
Cleaning Procedure
At the beginning of cleaning job, a fiber microscope should be used to inspect the fiber end, if it is contaminated as either images shows below, it should be cleaned with the dry cleaning method.
1.Blow the fiber surface with a stream of Clean Dry Air (the so called CDA), which will dislodge larger, loose particles. Keep in mind, don’t tip the can of the CDA while blowing. Because the liquid may be released contaminant on the surface of the fiber.
2.Place 1-3 drops of spectroscopic grade methanol or isopropyl alcohol in the center of a lens tissue. Do not use Acetone as a cleaning solvent on the fiber optical surfaces. Besides, to ensure the purity of the methanol or alcohol, you should never insert the lens tissue or swabs into the liguid.
3.Hold the fiber by the connector. Place the wet portion of the lens tissue on the optical surface and slowly drag it across. At this step, don’t use lens paper to dry it because the dry lens paper is extremely abrasive.
4.Examine the surface of the fiber under high density light using a magnifier, an optical loop, or a video inspection tool. If streaks or contaminants still remain, repeat the process using a fresh lens tissue.
5.Immediately install a protective cover over the end of the cable to avoid re-contamination or insert the fiber for immediate use.

Pluggable Fiber Optic Transceivers

An optical transceiver can best be described as a device that converts high-speed data from a cable source to an optical signal for communication over optical fiber. Optical transceivers are used to update the communications networks to manage broadband, to update the data center networks to make them manage traffic with higher speeds, to implement the backbone network for mobile communications.
For transceivers that plugs into Gigabit Ethernet and links to a fiber optic network, the Gigabit Interface Convertor is the standard and SFP is for small form factor pluggable transceiver. The GBIC transceiver operates as an input and output transceiver and is linked with the fiber optic network generally through the optic patch cords. GBIC transceivers are deemed to be ideal for any interconnections over the Gigabit Ethernet centers and for switches environment. The converters are virtually intended for high performance and continuing interactions that have need of gigabit or fiber channel interconnections. From SFP, users are able to generate connections utilizing the multi or single mode fiber optic ports along with the copper wiring.
The GBIC transceiver and the Cisco SFP offer companies with the opportunity to set up a Fiber Channel and Gigabit Ethernet connection effortlessly within their network. However, many Cisco GBIC transceivers would be the Cisco GLC-SX-MM, GLC-T, GLC-LH-SM, GLC-ZX-SM, and so much more. There are also 155M/622M/1.25G/2.125G/4.25G/8G/10G SFP optical transceivers, among which 155M and 1.25G are used widely on the market.
GBIC, SFP, SFP+, SFP, 1×9 covers low rate to 10G products, and is fully compatible with the global mainstream vendor equipment. And 10G SFP+ technology is becoming mature, with rising trend development of demand. 10G SFP optical module has been through development of 300Pin, XENPAK, X2, XFP, ultimately achieving to transmit 10G signals by the same size with SFP, and this is SFP+. SFP+, by its virtue of small size and low cost, meets the high-density requirements of devices to optic modules. Since 2010, it has replaced XFP and become the main stream in 10G market.
The SFP+ modules support digital diagnostics and monitoring functions, which are accessed through a 2-pin serial bus and provide calibrated, absolute real-time measurements of the laser bias current, transmitted optical power, received optical power, internal QSFP transceivers temperature, and the supply voltage. Digital diagnostic functionality allows telecommunication and data communications companies to implement reliable performance monitoring of the optical link in an accurate and cost-effective way.
Optical transceiver market driving forces relate to the increased traffic coming from the Internet. The optical transceiver signal market is intensely competitive. There is increasing demand optical transceivers as communications markets grow in response to more use of smart phones and more Internet transmission of data. The global optical transceiver market will grow to $6.7 billion by 2019 driven by the availability of 100 Gbps devices and the vast increases in Internet data traffic.
A palette of pluggable optical transceivers includes GBIC, SFP, XFP, SFP+, X2 form factors are available at Fiberyes. These are able to accommodate a wide range of link spans. The 10Gbps optical transceivers can be used in telecom and datacom (SONET/SDH/DWDM/Gigabit Ethernet) applications to change an electrical signal into an optical signal and vice versa.
