Description
Fiber optic splice closure is an equipment that used for optical fiber cable splicing, joint and protection. It is water proof and dust proof and suitable for outdoor aerial hanged, pole mounted, wall mounted, duct, buried application. It can be opened after sealing and can be reused without changing sealing material.
Application
SURCV016A dome type fiber optic splice closure is design and produced as per YD/T 814.1-2004 industry standard. It is suitable for fiber optical cable direct and branch splicing, connection protection.

Installation and adjustment
Open inspection
Open the packaging, check whether the products and accessories are complete, check whether the products are in good condition.
Tool
Please prepare the screwdriver, spanner, hacksaw, air gun etc.
Installation
CV016A can be aerial hanged or pole mounted application. Aerial hanged mounted and pole mounted accessories are optional.
Aerial hanged application
Fixed the one side of hook on the closure housing by screws, then put the other side of hook to the steel wire and fixed by screws. See below picture.

Use and operation
Please read the instruction manual.
Open the hoop, then open the closure.
Make sure the optical fiber cable length in closure and break out length are enough. See below picture.
A— cable fixing length B-- Cable with jacket length inside closure
C— Cable mini. length inside closure D— Break out cable length
Strip out cable outside jacket by pipe cutter and longitudinal stripper. The length is as per above 5.3 instruction or as per using condition.
Cut off the cable port by hacksaw, then open the cable port. (See below picture)
Optical cable installation
Put the stripped optical cable get through the heat shrinkable tube, closure cable port as per below picture.
Fix the cable strengthen core by cable fixing column. (See below picture)
Put the stripped optical fiber into fiber splice tray, do splicing and storage. (See below picture)

Optical cable heat shrink sealing
Identify the cable by oil pen and use grind paper to make rough surface of cable jacket
Heat shrink sealing
Wrapping aluminum foil paper on the optical cable, then put the heat shrink tube on cable port and junction of cable. Heat the shrinkable tube by air gun or alcohol burner, then the heat shrink tube fix the cable on cable port tightl
Sealing inspection & instruction requirements
1. The cable with jacket should be fixed by cable tie in the entry of splice tray.
2. Check the splice tray if close tray cover.
3. Check the inside fixing part if they are fixed tightly.
4. Check the sealing parts are in good condition.
5. Check the heat shrinkable tube sealing if tightly and completely.
Closure housing installation.
1. Put the closure housing close the splice tray and connect the closure base.
2. Fixed the closure housing and closure base by hoop.
