ELSFP Connector

ELSFP Module-Side Connector

Reliable fiber connection, easy maintenance, high-volume production ready

Metal Tab Design

Spring-loaded metal tab for secure mechanical retention
Simple installation and removal with basic fixture
MT-FA can be quickly removed without disassembling the connector body

MT Dust Protection System

First layer — dust plug applied after production testing, protects through assembly to final shipment
Full encapsulation of the MT-FA ferrule, superior to surface-contact solutions
Color coding: White = finished / Yellow = abnormal / Blue = semi-finished

Extended Boot & Drop Protection

Extended boot protects MT-FA ferrule during extraction — pull the boot, not the fiber
Boot has pull indicator and ring structure for easy fixture engagement
Reinforced side-wall protects against drop damage during handling

ELSFP Host-Side Connector

High-reliability host-side interconnect with advanced locking and protection

Quick Unlock & Pull Ring

Pull the ring to disengage — no separate unlocking tool needed
Locking hook rated for 3.2mm, maintains strength of original angled design
Color-coded rings for instant identification of wavelength, channel count, and fiber type

Zinc Alloy Shell — 40N Retention

Zinc alloy outer shell with PEI insulator for structural rigidity and thermal management
TE connector hook and body integrated as single piece, rated ≥ 40N
1.5mm ferrule setback enables two-stage alignment for smoother insertion

Integrated Dust Protection

Host dust plug installed immediately after connector testing to prevent contamination
Compact design does not interfere with metal Cage assembly
Cage dust plug and MT dust plug integrated into single unit — installed before switch shipment

Production-Friendly Design

Half-open base — MT-FA production and testing completed before connector assembly
Internal MT-FA can be replaced individually without scrapping the entire assembly
Bottom latch securely fixes Housing and Base, with dedicated disassembly feature for rework
