4 Characteristics

 

4.1      The closure is used for splicing part of main fiber cable with branching fiber cable, and meanwhile splicing its rest part with pigtail, connecting optical exchange equipment via patchcord. Therefore it saves costs by eliminating splicing unit, distribution unit, distribution box and all the work between fiber optic splice closure and distribution box.

 

4.2      It is easy and fast to increase FOST. The SLIDE-IN-LOCK design of FOST with the opening angle 90⁰ makes expansion and maintenance convenient.

 

4.3     The distribution unit can have FC, SC, ST, LC adapter front panel to meet with customers various needs. The installation is very easy.

 

4.4    Inovative design, easy installation. Based on the advanced formula, the plastic part is made of injection-molded, high-strength engineering plastic PC. It ensures long-term reliability and usage under ambient temperature -40°C- +65°C.

 

4.5         The elastic intergrated seal fitting, our patented product, can be reused for many times, it ensures good-resealing performance

 

4.6          Multi-functional fiber optic splice closure can be used for wall-mounting and pole-mounting application. It saves the cost for FTTH application and improve quality of telecommunication.

4.7         The closure is used for splicing part of main fiber cable with branching fiber cable, and meanwhile splicing its rest part with pigtail, connecting optical exchange equipment via patchcord. Therefore it saves costs by eliminating splicing unit, distribution unit, distribution box and all the work between fiber optic splice closure and distribution box.

 

4.8       It is easy and fast to increase FOST. The SLIDE-IN-LOCK design of FOST with the opening angle 90⁰ makes expansion and maintenance convenient.

 

4.9          The distribution unit can have FC, SC, ST, LC adapter front panel to meet with customers various needs. The installation is very easy.

 

4.10       Inovative design, easy installation. Based on the advanced formula, the plastic part is made of injection-molded, high-strength engineering plastic PC. It ensures long-term reliability and usage under ambient temperature -40°C- +65°C.

 

4.11         The elastic intergrated seal fitting, our patented product, can be reused for many times, it ensures good-resealing performance

 

4.12      Multi-functional fiber optic splice closure can be used for wall-mounting and pole-mounting application. It saves the cost for FTTH application and improve quality of telecommunication.
