This is an article introducing tow of the important fiber optic equipments, fiber patch cable and optical transceiver.
As the staff working for fiber optic telecommunication project, you must be very interested in the working life of fiber optic patch cable and optical transceiver. In the next text, I will introduce their working lifetime for you.
Fiber patch cable, or fiber jumper is the most used fiber optic cable plant equipments in the modern communications industry. Due to its long connection distance, low inset loss, good reproducibility and less return loss. It is able to support multiple devices work with features of interfix performance, not heat, good temperature stability. Fiber jumpers apply to cable networks, telecommunications networks, computer fiber optic network and optical test equipment.
Due to maintenance needs of transferring fiber optic jumper and normal testing, fiber optic connectors is always to be plugged. This makes the plug life the maximum pluggable times. This leads.
This problem is proposed based on the premise that: fiber optic connectors, under normal working conditions, by the provisions of the number of mating, each component mechanical damage, the additional loss does not exceed the limit value (usually the limit of the provisions of 0.2 dB). The optical connector plug life is generally determined by the mechanical wear of the components.
Optical fiber connector plug life can generally achieve greater than l000, the additional loss does not exceed 0.2dB. To the optical connector using slotted ceramic coupling sleeve, since the ceramic material is present to crack growth, the static fatigue will cause the sleeve to rupture. According to the information, the unscreened such sleeve, 20-year probability of rupture are 10-4. If the screening test force increase 2.6 times, then in 20 years will not rupture.
Fiber optic transceiver, as one of the important optical fiber transmission equipments, the working lifetime are closely related with the optical modules insides. The average service life is about five years. The long-term use of fiber optic transceivers, after five years, the main device, optical module, will not working properly because of the loss is too large and the laser damage.
