1. About this installation instructions
The TENIO ber enclosure is a modular enclosure that is composed of different building blocks to meet the specic client
needs. This installation instruction provides an overview of the building blocks and their variants and how they t together.
Environmental conditions in which the enclosure can be used are described in this document as well as product dimensions
and capacity (splice capacity, cable diameter range, and cable types).
In addition this instruction will explain:
- how to prepare the enclosure, feeder cable, and drop cables;
- how to install cables in the enclosure (including use of the CTU);
- how to route bers to the splice and/or patch trays or to the POC storage area;
- how to install bers on the trays;
- how to close and properly seal the enclosure;
- how to mount the enclosure with the mounting bracket; and
- how to use the external cable xation bracket.
This instruction also includes a section describing re-entry to the enclosure after installation for adding a new cable or for
accessing the ber management system.
2. Warnings and caution
2.1. Fiber optic cables may be damaged if bent or curved
to a radius that is less than the recommended minimum bend
radius. Always observe the recommended bend radius limit when
installing ber optic cables and patch cords.
2.2. Exposure to laser radiation can seriously damage the
retina of the eye. Do not look into the ends of any optical
ber. Do not assume the laser power is turned off or
that the ber is disconnected at the other end.

4. General product description
This enclosure is deployed in the distribution and drop part of the spliced ber network. It is designed to allow
reconguration in the eld, meaning the enclosure can be re-entered to add new cables as required.
Environmental conditions
The enclosure is designed to meet 20kPa and 2 m water head sealing performance compliant with prEN50411-2-10. It is
suitable for underground (manhole, handhole), ground level (pedestal) and aerial use.
The TENIO ber enclosure is a modular butt splice enclosure fully compatible with G.652.D SM ber. Fiber and cable
technology independent, it can be congured to meet specic requirements in terms of maximum splices, loop storage,
optical device storage, and cable diameter.
Two sizes are available, B6 and C6/C6H, to allow this exibility (see dimensions on the next page).

Maximum capacity of splices/trays
Trays are designed to hold SMOUV or ANT splice protectors depending on the type. A FAS is used in all splice trays. The
design of the tray provides bend control and makes sure the ber cannot make bends smaller then radius 40 mm (1.57’’).
Minimum over length storage per splice side on the tray is 1.2m (47’’).
Tenio-B6 can accommodate up to 12 ber splice trays (type S12 or A12). Each tray houses 12 ber splices, for a capacity of
maximum 144 ber splices per closure.
Tenio-C6 can accommodate up to 8 ber splice trays (type S24 or A24). Each tray houses 24 ber splices for a capacity of
maximum 192 ber splices per closure.
Tenio-C6H can accommodate up to 12 ber splice trays (type SLE). Each tray houses 24 ber splices for a capacity of
maximum 288 ber splices per closure.
More information about tray types can be retrieved in installation instruction TC-1320-IP-A, and on the eCatalog.
Cable diameter range
The cable diameter of the TENIO ranges from 2-16mm (0.08-0.63’’).
Depending the required cable range, the enclosure can be composed of various combinations of dedicated cable seal
segments. The TENIO can hold in total 6 seal segments. Each seal segment (9 variants in total) is adapted to a specic cable
range. For an overview, refer to the eCatalog. These gel seals are put under pressure after installation by engaging the seal
mechanism. The seal mechanism exists of 2 latches to seal the dome on the base and a tightening system engaged with the
trigger to seal the cables.
Cable type
The TENIO is cable technology independent and can be used with various cable constructions for both feeder cable and drop
cable, including microsheath, dual strength member, central core, and loose buffer tube/subunit constructions.

Large CTU (CTU-L) can terminate strength members (rods
up to Ø 4mm (0.16’’) and aramid yarn).
In one CTU holder 2 or 3 of these CTU’s can be installed.
Cable diameter range from 5-16 mm (0.20-0.63’) and at
cable.
Small CTU (CTU-S) can terminate aramid yarn. 4 or 5 of
these CTU’s can be installed in one CTU holder. Cable
diameter is up to 6 mm (0.24’’).
4.2.7. Cable seal
The enclosure is sealed with in total 8 gel seal segments. Two
of the seal segments are the side seal segments and do not
hold a cable.
The other 6 segments can vary depending on the amount of
cables and diameter of cables required. For an overview,
refer to the eCatalog.
The gels seals are available in the SKG’s (sealing kit gel).
4.2.8. Loop storage area
Unused looped tube/subunits can be stored between the
metal brackets at the back side of the organizer If the unused
loops of the feeder cable should be stored, the feeder cable
should be installed in the middle gel seal segment at the
back side of the enclosure.
4.2.9. Fiber dressing tool and wedge
A ber dressing tool to guide the bers under the hooks and
lips of the tray and the channels, is stored at the backside
of the organizer. It is advised to store the ber dressing tool
again in its holder after installation.
A wedge to support the trays is only available in the C6
enclosure in combination with the A24/S24 tray. The purpose
of it is to prevent the tray from falling down when hinged
open to work on the tray below.
4.2.1. Towers
The towers contain the snap features to hold the trays.
There are two towers available, with a different pitch between
the trays. The tower mounted on the B6/C6H size has a
pitch of 4mm. The tower mounted on a C6 size has a pitch
of 6mm.
4.2.2. Trays
Trays should be mounted on the tower in the eld. They are
either part of the kit content or can be ordered separately.
See the eCatalog for more information about the different
types.
Splice trays as well as patch trays are available to use in
the TENIO. Splice trays are designed to hold SMOUV or ANT
splice protectors depending the type. A FAS is used in all
splice trays, providing an R40 bend radius. Minimum over
length storage per splice side on the tray is 1.2m (47’’).
4.2.3. FAS (Fiber Arrangement System)
The two drums in the FAS area are used to redirect the ber
routing. Fibers can change direction by making an S-shape
over the drums. The area is also used to allow inter tray
jumps: bers routed from one tray to the other need to
pass the FAS. Also on the trays a FAS is used to redirect the
routing of the ber.
4.2.4. Passive optical components storage
Depending the application, ber storage (for example dark
ber) can be stored in this area as well as passive optical
components (POC). A dove tail interface cut out is used
to install the POC’s in this area. The C6 size enclosure can
accommodate more POC’s then the B6 size. Field installable
splitter sub-assemblies with Fused biconoc Taper (FBT) or
PLC splitters are available. See eCatalog for more details.
The ber guidance channels bring the bers to the trays, the
FAS or to the POC storage area.
4.2.5. Tube/subunit holder
Tube/subunit holders are present on the front side as well
as on the back side of the organizer. In the tube/subunit
holder area, the jacket is removed from the tubes/subunits.
Only 250µm ber continue from this point. The area is
designed to control tube/subunit grow in/ grow out up to
20 mm. The tube/subunit is pushed in one of the channels
and the ber is routed to ber guidance channels left or
right. The ber can also be guided from the back side of the
organizer to the front side to access the trays.
To keep the tube/subunits in place, a piece of orange tubing
is cut to length and pushed on top of the tube/subunit.
A pre-installed transparent protection lid covers the tube/
subunit holder.
4.2.6. CTU holder area
In the CTU (Cable Termination Unit) holder area, the black
CTU holders are installed. The black CTU holders are
available in the SKG’s (sealing kit gel). There are 2 models,
one model for small CTU’s (CTU-S) used with cables with a
diameter up until 6 mm (0.24’’), and one for large CTU’s
(CTU-L) used with cables with a diameter up to 16mm (0.63’’)
