 Easy to Install、Clear Identification

The fixing mode of insert-box 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.

   Compliance with International Standards

The DWDM insert-box module of FOCC conforms to RoHS, Satisfies TelcordiaGR-1209 and GR-1221.

	Lower Insertion Lower insertion loss makes DWDM insert-box module have lower signal attenuation in operation, thus reducing the power requirement of signal transmitter.
Higher Isolation The higher isolation value enables sufficient signal isolation during multi-signal transmission in the DWDM insert-box module, effectively preventing crosstalk between signals and causing distortion of the transmission signal.
	Mature Production Technology The DWDM insert-box module of FOCC has mature production technology, stable and reliable performance, supports the work in the harsh environment of - 40 ~ +85 ℃, and ensures the stable transmission of signals.
