MBN-FOSC-A16 inline fiber splice closure
The MBN-FOSC-A16 is an inline optical fiber enclosure for protecting cable splices in straight-through or branching connections. The published model specification lists a maximum capacity of 288 cores and four cable ports arranged as two entries and two exits.
Use the maximum capacity as a configuration limit, not as a statement of the supplied tray count. Before ordering, confirm the cable construction, splice arrangement, tray loading and mounting accessories for your project.
Model specifications
| Item | Published specification | What to confirm |
|---|---|---|
| Model | MBN-FOSC-A16 | Model and configuration on the quotation and drawing |
| Enclosure type | Inline fiber splice closure | Straight-through or branching cable layout |
| Maximum capacity | Up to 288 cores | Required splice count, installed trays and reserve capacity |
| Cable ports | 4 ports: 2 entries and 2 exits | Cables assigned to each port and plugs for unused ports |
| Dimensions | 54 × 26 × 14 cm | Dimension orientation, mounting clearance and access for maintenance |
| Housing material | PP | Project-specific material and environmental requirements |
| Cable diameter | Requires configuration confirmation | Send the actual outer diameter of every cable; obtain the approved port and seal range before ordering |
| Sealing arrangement | Configuration-dependent sealing components | Seal type, cable compatibility and replacement parts for reopening |
Cable fit must be confirmed: ask for the approved A16 drawing and seal-kit specification for the actual outer diameter of every cable. Confirm the port, retention and sealing components as a matched configuration before placing the order.
Choose the configuration before requesting a quote
- Splice capacity: state the initial and planned splice count. Confirm tray quantity and the arrangement for single-fiber or ribbon splices before assuming the maximum capacity is available in the supplied configuration.
- Cable entries: list cable count, outer diameter and construction for each port. Confirm cable retention, sealing components and unused-port plugs together.
- Installation location: describe aerial, wall-mounted, duct or buried use. Ask for the mounting kit and documented suitability for the chosen location; a generic installation list is not proof of a burial or immersion rating.
- Metallic cable components: identify armor or strength members and request the appropriate retention and bonding arrangement where required by the project.
- Maintenance: confirm access space, splice identification and replacement sealing components for future reopening.
Installation and acceptance checks
Use the installation instructions supplied for the selected enclosure and seal kit. This product overview does not replace an installation procedure. Obtain the specified fastener torque, tightening sequence, cable preparation and sealing method before work begins.
- Check the delivered model, enclosure, trays, seals, cable-retention parts and mounting accessories against the approved order.
- Verify cable fit and the port assignment before preparing the cables. Do not improvise a seal or clamp arrangement to compensate for an unconfirmed cable diameter.
- Route and protect fibers using the tray and cable manufacturer’s limits. Keep splice identification and planned spare capacity accessible.
- Close and mount the enclosure according to its supplied instructions. Use only the specified sealing test method and test conditions.
- Complete the project’s optical acceptance checks and retain the results with the installation records. An enclosure does not remove the need to verify the installed link.
For a specified environmental rating or standards requirement, request the applicable model-specific documentation and test report. Confirm that the documents identify the configuration and test conditions relevant to your installation.
Purchasing questions
Does a 288-core maximum mean 288 splices are included?
No. Maximum capacity and the supplied configuration are different. Confirm the tray count, splice arrangement and included accessories on the quotation.
Can this closure accept my cable diameter?
Send the outer diameter and construction of each cable. Require written confirmation of the matching cable port, retention and seal components; do not infer compatibility from the enclosure dimensions alone.
Are aerial or wall-mounting accessories included?
Aerial and wall-mounting accessories are listed as optional. Specify the intended mounting method and confirm the required kit in the order.
What should I include in an A16 inquiry?
Send the model, quantity, splice count, cable count and diameters, installation location, mounting method, required documentation and desired arrival date. Ask for confirmation of the configuration, price and delivery schedule before approving the order.
