*The body adopt modified plastic MPP,which is high strength and corrosion resistance,has longer lifetime and excellent sealing performance.

*It has 7 cable ports in total,6 Φ20mm round cable ports,and 1 oval port which can let in and out 1pc Φ42mm cable or 2pcs Φ20mm cables,as well as for few small size cables at the same time. 

*The closure can be reopened,which is maintenance friendly.It can work well in the environment of -40℃~+65℃ and guarantee the good sealing performance.

*Leak proofness:inflate the closure,making internal pressure to 100Kpa,then put the closure into the water over 15min,without any bubbles or pressure drop happened.

*Impact Strength:can bear 16N.m.after 3 impact times,there is no crack on the body. 

*Assembled with valve core and grounding device.

Dome Fiber Optic Splice Closure

NS-M7RS-B type of dome closure series,used for direct connection during optical fiber transmission process,and provides joint connection protection,with 6 small round cable holes and 1 large cable hole;heat sealing with heat shrinkable casing;can be used for overhead,pole,wall and buried installations.With good sealing performance,the simple installation and wide application range are the best choice for optical fiber connection.

fiber enclosure


*All functional indicators are in line with the national YD 814.1-2004 standard for distribution box.

*Four-in and four-out cable ports; there are 1 large and 6 small circular holes, which can enter and exit the Φ7~Φ22 optical cables.

*The outer box body is made of high-strength engineering  plastics, It has features of light weight, high mechanical strength, anti aging, strong corrosion resistance, lightning resistance, and long service life.

*Stacked structure splice tray and independent insulation grounding device make the optical fiber core configuration, expansion and the cable grounding flexible, convenient and  safe.

*The splice tray is equipped with splicing slots and a PLC splitter holder, which can be configured at any time    according to the needs of direct or divergent connection.

Fiber optic splice enclosures are used to protect stripped fiber optic cable and fiber optic splices from the environment, and they are available for indoor as well as outdoor mounting.

Outdoor fiber optic enclosures are usually weatherproof with watertight seals.

In a typical wall-mounted splice enclosure, fiber optic cable is supported by cable ties, and the cable strenght member is securely fastened to the enclosure’s support. Metallic strenght members must be grounded securely.

The cable jacket(sheath) stops at the splice enclosure’s cable ties. Optical fiber tubes, individual tight buffered fibers, or pigtails are supported by the tube brackets and continue to the splicing trays.

Individual optical fibers should never be exposed outside of a splice tray. Fusion splices or mechanical fiber optic cable splices are contained in the splice trays.


Large number of cable entry knockouts for incoming and outgoing cables;

Key-lockable main door to prevent accidental opening of splice compartment;

Able to hold up to six MTP loaded cassettes;

Standard accessory kit for cable entry and fibre management included;


Ideal for fusion splicing

High fibre density applications

Repairing damaged cables

Suitable for direct termination

Remote cable terminations within building
