Description

Description 4E1 PDH Multiplexer can multiplex 4E1 and 2 optional port Ethernet (*0/**0Mbps line speed) signals in one fiber channel to transmit. It is suitable for low capacity, point-to-point application of remote transmission. The circuit part of the equipment is fully digitized. The whole equipment is reliable, stable, easy to install and maintain. It has good temperature and voltage characteristics, complete alarm functions, one RS**2 asynchronous interface and remote loop back functions(from software). At the same time, it can be managed from management software Fi-View-MP Features Provide up to 4E1 channels and 2 optional port *0/**0Mbps Ethernet channel Fiber port bit rate: **0Mbps, up to **0Km distance without repeater E1 Line code: HDB3, compliant to G.**3, G.**3 and G.**2. E1 channel support both *5ohm & **0ohm impedance Ethernet port support *0/**0Mbps auto-detection, Full/Half Duplex auto-negotiation Ethernet port can transmit VLAN tag Complete alarm functions Provide an RS**2 asynchronous interface Support the local/remote E1 loop back Remote loop back provided by software and hardware Provide RS**2 port for management, GUI interface Stand alone, **0VAC or **8VDC power supply optional Application Specification â– Optical Port Port number: 1 Bit rate: **0Mb/s+/**0ppm Wavelength: ***0nm, ***0nm Distance: 0 - **0Km Connector: FC/PC â– E1 Port Port number: 4 Bit rate: 2.**8Mbps(+/***0ppm) Impedance: *5ohm or **0ohm Line Code: HDB3, compliance with ITU-T G.**3 â– Ethernet Port Port number: 2 optional Speed: *0/**0Mbps line speed Duplex: Half/Full auto-negotiate Frame Size: *4 - ***6 bytes MAC address: 1k MAC aging time: 5mins Power Supply Input voltageï&frac*4;šWhen **8Vï&frac*4;Œ **0V ï&frac*2;ž **0V (DC) is allowed When ~**0Vï&frac*4;Œ ***5V ï&frac*2;ž ~**4V (AC) is allowed.
