Direct answer
LC/SC alignment sleeves and housings have different roles. Record their materials, dimensions and complete parts separately. Sleeve ID, OD and withdrawal force are not one property, and a subcomponent report does not establish complete mating performance. Substitutions also need mounting, latching and connector-pair review.
Separate sleeve and housing material fields
SENKO's sleeve page lists material, ID, OD and withdrawal force. Its SC TOP page separately identifies housing, hook and alignment sleeve. A ceramic-adapter or metal-adapter label can omit which part the material describes.
This guide concerns cylindrical-ferrule interface review, not a dimension table for every connector. For MPO or other constructions, use the exact mating requirements instead of transferring LC/SC component assumptions.
| Object | Review | Does not replace |
|---|---|---|
| Sleeve | Material, dimensions, construction | Complete adapter evidence |
| Housing | Material, shape, mounting | Sleeve identity |
| Latch/retention | Mating and fixing arrangement | Optical tests |
| Panel interface | Cutout, thickness, datums | Connector compatibility |
| Mated assembly | Both connector parts and method | Every possible combination |
Keep ID, OD and withdrawal force separate
SENKO's table also identifies length, slit and chamfer. A similar diameter does not establish equivalent construction.
ID requirements and the OD used in assembly are different fields. Give drawing dimensions their datums and approved tolerances; do not turn photo-based estimates into manufacturing requirements.
Retain the test object and method for withdrawal force. A sleeve/defined-test-piece result cannot simply be renamed connector release force or panel retention. Ask what was pulled and where it was measured.
Retain the mating conditions with optical values
The SC TOP loss table includes a Master Grade jumper-to-Low Loss mating footnote. No value is adopted here as a universal limit. Preserve the combination rather than copying an isolated dB field.
List both connectors, adapter and reference setup during substitution review. Archive sleeve information as component evidence; finished loss, endface and mating requirements need their corresponding records.
Panel fit is one check
After confirming the cutout, review approved mating, locking and service access. Retain panel thickness, fixing and front/rear clearance, then evaluate samples with the planned mating parts.
Color alone does not establish sleeve material or optical grade. Identify protection options by configuration; a dust-protection component is not proof of endface inspection.
| Deliverable | Include | Purpose |
|---|---|---|
| Material list | Housing, sleeve, fixing revisions | Identify substitutions |
| Component drawing | ID, OD, length, datums | Separate dimension objects |
| Installation drawing | Panel and mating positions | Fit and service access |
| Mating tests | Connector pair, method, results | Finished scope |
| Change notice | Changed part and validation | Review prior evidence |
Define the substitution boundary
For a sleeve change, identify which original evidence remains applicable. A housing-only change also needs review of latching, installation and relevant environmental records. Let the responsible party determine affected checks rather than assigning every color or material change the same risk.
No ARRANEX use of a cited sleeve or its durability, loss or temperature grade is claimed. Start with complete interface and panel drawings to organize requirements.
Procurement FAQ
- Does metal housing mean a metal sleeve? Identify housing and internal material separately.
- Is sleeve ID enough? Retain OD, length, construction and mating requirements.
- Is withdrawal force connector-release force? Establish the object and method first.
- Does a sleeve report establish finished insertion loss? Obtain evidence for the complete mating combination.
- What belongs in the RFQ? Interface, panel drawing, component requirements, mating parts and validation scope.
