Single-port SFP+ 1×1 cage without light pipe, full metal EMI shielding, press-fit 20-position receptacle, 0.8 mm pitch. Drop-in replacement for TE 2170039-1 / 2057159-1 / Amphenol U77A1118200T. Supports SFP/SFP+/SFP28 modules. Factory direct, MOQ 500 pcs, samples 5 days.
🛡️ Solid Metal Wall – Zero Light Pipe Aperture = Maximum EMI – No plastic light guide means the stamped copper-alloy / nickel-silver cage stays a continuous RF shield with no leakage gap. External + internal beryllium-copper spring fingers give ≥60 dB @ 1–10 GHz, comfortable FCC/CE Class B even at 10G/25G.
🔌 20-Position Press-Fit Receptacle, 0.8 mm Pitch – Right-angle through-hole header, phosphor-bronze contacts, gold flash on mating area, compliant press-fit tails (Ø0.64 mm, 2.05–3.0 mm tail). Solder-free PCB mount, survives standard SMT reflow + pin-press.
🎯 True Single-Port Economy – 1×1 is the lowest-cost entry into SFP I/O: one module slot, smallest front-panel cutout (≈ 48.6 × 14.5 mm), no ganging tolerance stack-up. Ideal for media converters, industrial DIN switches, 1-port NICs, diagnostic cards.
🔄 Pin-to-Pin Cross to TE / Amphenol / Molex – Land pattern matches TE 2170039-1 (SFP 4G), 2057159-1 (SFP+ 16G), 2007198-1; Amphenol U77A1118200T; Molex 74737-0004. Legacy boards swap with zero re-spin.
💰 BOM-Minimal & Field-Proven – Removing light pipe + heat sink option cuts component count and assembly steps. Same mechanicals trusted in telecom access gear for 15+ years; we add ISO 9001batch traceability and 100% continuity test.
