Features
![]() | Lower Insertion Loss Lower insertion loss makes FWDM LGX module have lower |
| Higher Isolation The higher isolation value enables sufficient signal isolation | ![]() |
![]() | Mature Production Technology The FWDM LGX module of FOCC has mature production |
Convenient Installation Method
The FWDM MUX and DEMUX LGX module of FOCC can be used independently, It can also be used with 1U rack, It’s LGX is designed according to 1/3 of the 19''rack size. Three LGX modules of this type or other types can be matched on a single 1U rack. Increase the utilization rate of 1U rack.

Compliance with International Standards
The FWDM MUX and DEMUX LGX module of FOCC conforms to RoHS, Satisfies TelcordiaGR-1209 and GR-1221.

Easy to Install、Clear Identification
The fixing mode of LGX module box and rack is rivet type fixing buckle, which is made of Nylon material approved by UL94V-2. It is easy to install and disassemble. Each LGX module panel working port has a wavelength mark printed by laser, which is convenient for users to identify.

Application
FWDM MUX and DEMUX LGX module products have the characteristics of wide channel bandwidth, low insertion loss, high channel isolation and high environmental stability and reliability. Its function is to MUX multiple signals into one optical fiber for transmission, or to DEMUX multiple signals in one optical fiber. It greatly reduces the access cost. It can meet the high broadband demand of data, voice, CATV and other integrated services, It is widely used in combination with triple play, FTTX, etc.
