3 . Structural features

(1) GPX01-A series of fiber optic patch panels and sub- frame: 19 " international standard installation interface ; surface using electrostatic spray coating process , corrosion resistance, aesthetic appearance ; applicable to all forms of existing cable structures .

( 2 ) the frame with closed cabinet structure, cable and wiring into the side to avoid the physical protection of optical fiber, cable accidental damage . Frame body design uses a modular structure, complete accessories , can be flexibly configured to fight rack installation can be achieved according to the different requirements of users , easy capacity increase .

( 3 ) the top or bottom of the rack by the cable into the cable hole patch fixed the introduction , grounding and protection. Cable and cable from damage in the core , the metal parts and chassis cable insulation , metal-sheathed cable and strengthen the core fixed reliably connected high voltage protective grounding device .

(4) GPX01-A fiber optic distribution boxes ( sub- frame ) of the Big Wheel using welding wire integration module. Stratified rotating module structure , easy management , safe operation. Card installed FC, SC, LC and ST four kinds of adapters, adapter was 30o arrangement that ensures fiber bending radius jump ≥ 40mm, and avoid eye laser burns . The series can be used with jumper wiring boxes accommodating tray while installation.

( 5 ) Jumper by vertical groove alignment and horizontal wireway management, optimize the layout alignment , and to retain access for Erecting a jumper , closing circling over fiber can store extra jumpers.

( 6 ) fiber optic pigtails, jumpers clearly marked .
