S325 Fiber Cleaver

1.

INTRODUCTION

In the fiber splicing work for FTTH implementation within
the users’ premises and for LAN implementation, there isa need for a fiber cleaver that is easy to use yet high inreliability. Accordingly, we have developed a new fibercleaver S325 that features significantly reduced operation
procedures while allowing for hand-held operation. The
S325 is provided with a waste fiber collection function
whereby our conventional cleavers have achieved a highreputation.

FEATURES

2.1 Appearance
The main body has a form that permits easy hand gripping. The S325 not only allows hand-held cleaving offibers in various working environments conceivable in any
termination splicing, but also enables cleaving with ashort length of excess fiber since the cleaver can bebrought into a cable closure.

2.3 Compact Size and Light Weight
The S325 has been reduced in weight to nearly 330 g,
about 2/3 of our conventional fiber cleaver the S323.
2.4 Ease of Operation
While with conventional fiber cleavers the actions such as
the fiber cleaving, waste fiber collection and resetting
have to be performed separately, the S325 permits aseries of these actions to be performed by a single touch

2.2 High Portability
Because of its compact size and light weight, the S325
can be carried to any splicing locations. The S325 comeswith an attachable hand strap, which can be used as aprecaution against accidental falling of the equipment.
You can also use a neck strap to suspend it around yourneck.

S325 Fiber Cleaverof finger. The fiber cleaving actions including waste fiber
collection will be automatically completed simply by setting a fiber holder on to the cleaver, closing the lid andpressing the cleaving lever. The cleaving blade is automatically restored to its original position by opening thetop lid after a cleaving action. This significantly reduces
mistakes in cleaving operation, improving working efficiency.

2.5 Maintenance
The sliding unit that holds the blade is detachable fromthe main body, permitting easy exchange of the blade.
The height of blade after exchange is adjustable without
using any special tool.
