PreCONNECT® SEDECIM - optimal cabling for parallel optical data transmission via 400GBASE-SR8
MTP® cabling system perfectly fitting for SR8 and DR8/PSM8 applications
PreCONNECT® SEDECIM is a comprehensive system for structured parallel optical data transmission cabling. By using 16 fibres for each MTP® connection, Rosenberger OSI has created a high-performance, efficient multifibre cabling product that optimises results by reducing both costs and attenuation.
The cabling system for parallel optical SR8 and DR8/PSM8 consits of:
- Factory-assembled fibre optic breakout cables, FRNC-LSZH indoor cables, up to 9 x 16 = 144 fibres with connector systems MTP® 16 fibre per MTP® channel
- MPO/MTP® port breakout with MTP®-LC and MTP®-MDC harnesses, MTP® module cassettes with LC and MDC front and MTP®-LC port breakout units
- Two 19“ panel systems SMAP-G2 HD and SMAP-G2 UHD selectable
- Suitable patch cords
- Useful accessories
- Patch location rack

Features
- For all who already have on minimum one cabling side MPO16 fibre based parallel optics SR8 and DR8/PSM8 transceivers
- Cost and attenuation optimised for SR8 and DR8/PSM8 applications
Fields of application:
MTP® (MPO) based data centre cabling with 16 fibres per MTP® channel
Optimised for parallel optics MPO 16 fibre applications:
- 400GBASE-SR8
- 800GBASE-SR8
- 800GBASE-DR8
- 800G-PSM8

Properties of individual system components
PreCONNECT® square interface and installation protection:
Rosenberger OSI already brought high fibre-count factory-assembled fibre optic trunk cables to the market in 1991. PreCONNECT® STANDARD was the first high fibre-count and modular „plug and play“ fibre optic cabling system developed and manufactured in Europe, and in 1997, we were the first manufacturer of MTP® cabling systems in Europe.
PreCONNECT® SEDECIM breakout trunks have PreCONNECT® square interfaces on both sides, which can be tool-less hooked into the 19” panel systems for tension- and torsion-resistant fixing of the trunks.
The trunk connector legs are fits the 19“ panel systems and are packaged in non-pull-resistant dust-proof foil tubes. Upon request, installation tubes with tensile strength, crush resistant, kink resistance, and torsion resistance are deliverable.
Connector types:
- To reach reliably high return loss in multimode applications as well, the MTP® 16-fibre multimode connectors of PreCONNECT® SEDECIM OM4 are APC 8° polished, with white boot as a color code.
- The MTP® 16-fibre singlemode connectors of PreCONNECT® SEDECIM SM are APC 8° polished, like all MTP® singlemode connectors so far, with a green connector housing as a colour code.
- MTP® 16-fibre connectors have an off-center key
- SEDECIM breakout trunks: MTP® 16-fibre, APC 8°, male
- SEDECIM patchcords, harnesses and module cassettes: MTP® 16-fibre, APC 8°, female
Adapter types:
- MTP® by16 multimode: off-center key, TIA type A “opposed key” „1 to 1“, white
- MTP® by16 singlemode: off-center key, TIA type A “opposed key” „1 to 1“, green
Polarity:
- SEDECIM breakout trunks: TIA Method B „1 to 16“
- SEDECIM patchcords, harnesses and module cassettes: see pages of the products
Cable types:
- SEDECIM breakout trunks: I-F(ZN)H(ZN)H 16 fibres CPR class B2ca and I-F(ZN)HH n x 16 fibres CPR class Cca
- SEDECIM patchcords and harnesses I-F(ZN)H and I-F(ZN)H(ZN)H 16 fibres
- Cable data, see separate cable data sheets
Fiber types:
- Multimode OM4 bend-insensitive
- Singlemode G.657.A1 bend-insensitive and backwards compatible to G.652.D
- Fiber data, see separate fibre data sheets
Operating temperature range: -10°C to +60°C
Length definition: Order length = length between the connectors of the longest legs at both sides, not between the PreCONNECT® square-interfaces.
Delivery form:
- Dependent on the length as cable ring or on cardboard or wooden drum
- Insertion loss and return loss measured acc. to IEC 61300-3-4, method B, MM 850/1300 nm and SM 1310/1550 nm, with measurement protocol
- Product label with serial number at both sides
Patch Location Rack:
Applications:
- High-density data centre infrastructures
- For the construction of ultra-high-density data centre patch locations
Properties:
- Innovative, restriction-free cable management system
- Rack pillars with integrated cable managers to prevent interference with cable routing
- The covers of the cable managers fold in both directions and are completely removable
- Individually selectable feedthroughs in the sides and rear walls of the large-volume cable channel for simple vertical and horizontal cable routing
- Professional routing of large cable volumes from the patch fields and storage of excess cable lengths in the vertical cable managers
- Particularly suitable for fibre optic cables thanks to the use of cable clips (L-fingers) and finger slots:
- The rounded L-fingers ensure that the cables are highly protected against bending and kinking even when under strain
- The L-fingers do not have any sharp edges and are extremely strong and resistant to breakage - Because there is plenty of space for them in the large finger slots, the cables are neither compressed nor kinked.
- The L-fingers secure the cables in the finger slots whenever you need to work with the covers folded back or removed.
Dimensions (H x L x W): 213 (46 HU) x 90 x 90 cm
Material and colour: powder-coated steel, RAL 9005 (black)
