Product overview & intended applications (Background — exact description)
What the AV87-15R4ATN is (connector type & core specs)
Point: The AV87-15R4ATN is a multi‑fiber MT receptacle in a 4‑plex MT style intended as a rugged, wall‑mount/receptacle connector. Evidence: The datasheet lists family, shell style, fiber position count, and mounting type as primary identifiers. Explanation: When recording part details for procurement, capture the part‑number breakdown, number of fiber positions (4), shell style code, contact/ferrule type, and mounting orientation to avoid mismatches in BOM and drawing callouts.
Typical applications & system roles
Point: This connector targets mil/aero and ruggedized industrial roles where density and environmental resistance are required. Evidence: Typical system uses include airborne platforms, ground vehicles, tactical comms racks, and sealed enclosures. Explanation: Choose AV87-15R4ATN‑class parts when vibration, sealing, and panel‑mount security override the small cost/termination benefits of generic MPOs; always reference environment and interface requirements (temperature, ingress, panel thickness) during part selection.
Key optical & signal specifications (Data analysis)
Optical performance metrics to extract from the datasheet
Point: Focus on insertion loss (typical vs. max), return loss/ORL, supported fiber format (single‑mode vs. multimode), and channel count. Evidence: The datasheet's specs section typically lists typical insertion loss (example ranges 0.2–0.5 dB), maximum allowed loss per mate, ORL thresholds, and alignment/tolerance notes for MT ferrules. Explanation: Use these values to calculate link budget impact — set acceptance thresholds (e.g., post‑qualification max IL ≤ datasheet max + margin) and flag any ORL limits affecting high‑power or DWDM links.
Electrical and signal integration considerations
Point: While optical, integration can have electrical implications such as EMI/EMC and grounding of metal shells. Evidence: The connector shell and backshell choices affect conductivity and shield continuity; transceiver/adaptor compatibility imposes polarity and keying constraints. Explanation: Specify grounding/EMI requirements in procurement, verify shell continuity in assembly, and require insertion loss verification plus end‑face inspection after termination to confirm optical performance and correct polarity.
Mechanical, environmental & reliability specs (Data + methods)
Mechanical dimensions, interfaces & mounting
Point: Critical mechanical fields are shell size, panel cutout, depth, mating face geometry, and mounting type. Evidence: The mechanical drawing in the datasheet shows panel cutout dimensions, hole patterns, and recommended torque for fasteners. Explanation: When preparing panel drawings, include callouts for cutout tolerances, recommended thread engagement, and maximum panel thickness; require vendor drawing numbers and 2D/3D CAD files in the procurement package to avoid fit issues.
Environmental ratings & reliability data
Point: Extract operating temperature range, sealing/IP equivalence, shock/vibration qualifications, mating cycles, and corrosion finish. Evidence: Datasheet rows list temperature limits, qualified shock/vibe levels, number of qualified mating cycles, and plating/finish details. Explanation: Use these specs to drive qualification tests: post‑vibration insertion loss limits, seal leak checks, and corrosion spot checks; set lifecycle expectations by specifying minimum mating cycle acceptance and environmental soak criteria for production samples.
Installation, termination & compatibility guide (Method/How-to)
Recommended termination and mating considerations
Point: Field and factory termination steps center on cleanliness, alignment, and controlled mating procedures. Evidence: MT‑style ferrules require end‑face inspection, controlled polishing/cleaving if field‑terminated, and staged mating to seat keys without damaging fibers. Explanation: Use this short installer checklist: inspect end‑face with a video probe, verify polarity, confirm panel alignment and mounting torque, perform insertion loss and return loss tests after mating, and document results in the assembly record.
Accessories, backshells & panel integration notes
Point: Common accessories include dust caps, gaskets, protective backshells, and strain relief options that influence sealing and cable routing. Evidence: Datasheet accessory lists and mechanical drawings identify compatible backshell geometries and gasket part numbers. Explanation: In the BOM, call out backshell/latch options, gasket material and thickness, and confirm routing clearances; verify accessory compatibility against panel cutout and mating connector envelope prior to production ordering.
Performance comparison & procurement checklist (Case study + Action)
How AV87-15R4ATN compares to similar connectors
Point: Comparison should balance density, ruggedness, optical loss expectations, environmental resilience, and termination complexity. Evidence: Use a simple spec matrix to compare insertion loss, mating cycles, operating temp range, and mounting style. Explanation: AV87-15R4ATN‑class parts typically trade slightly higher termination effort for improved environmental rating and secure panel mounting; prefer them where reliability under shock/vibe and ingress protection are priorities.
