PDH | P180

Gigabit Ethernet and 16E1s to optical fiber multiplexer

ZS-P180-(1+1)Dual Fiber-16E1-4GE-R

The ZS-P180-(1+1)DUAL FIBER-16E1-4GE-R is optical transmission equipment based on Application Specific Integrated Circuit (ASIC). It integrates the traditional PDH multiplexer and 1000Mbps Ethernet optical transceiver, and can realize the 4/8/16 E1s and four 1000Mbps Ethernet data channel transmission over optical line of 1.25Gb/s, the four 1000Mbps Ethernet data channel share 1000M bandwidth.


l  Compact design with 1U height, and can be installed on standard rack

l  Realizes up to 16 E1s and four 1000M Ethernet mixed multiplexing to optical fiber

l  Optical interface

ü   Dual optical interfaces, SFP optical module (LC interface), Hot plugging

ü   The line bit rate is 1.25Gb/s, transmission distance is optional (depend on the SFP optical module)

ü   SFP MSA(INF-8074i), ITU-T G.695, FC-PI V2.0 standards compliable

ü   Supports 1+1 optical protection and Automatic Protect Switch (APS) with the recovering time less than 50ms

ü   Provides optical loopback function, a great convenience for trouble shooting

ü   Supports ALS function

ü   Supports Remote Power down Detect (RPD) function, which can be used to distinguish the failures of remote power down or fiber broken

l  E1 interface

ü   Provides 4/8/16 E1 interfaces, compliant to G.703, and balanced/unbalanced selectable

ü   Jitter tolerance, jitter transfer characteristic and jitter generation fully comply with ITU-T G.823 and G.742 recommendations

ü   Local/remote loop-back function supported

ü   Supports device loop and E1 line loop controlled by the local side, which is convenient for E1 line testing

ü   Supports embedded E1 BERT function

l  Ethernet interface

ü   One optical Gigabit Ethernet interface and three electrical Gigabit Ethernet interfaces compliant with IEEE802.3 serial standard

ü   The electrical gigabit Ethernet interfaces adopt RJ45 connector, support auto-negotiation, which can work in 1000M full-duplex, 100M full/half-duplex, 10M full/half-duplex mode

ü   The optical gigabit Ethernet interface adopts 1000M SFP module, which can work in 1000M full-duplex mode

ü   Proprietary technique (patent pending) adopted to prevent Ethernet frames from looping back in case of unexpected optical loopback

ü   Supports unicast, multicast and broadcast frame

ü   Supports flow control and broadcast storm filtering control

ü   4K MAC address table

ü   Supports MAC address dynamic learning function

ü   Supports port rate control function

ü   Supports port-based VLAN and IEEE 802.1Q tag-based VLAN

ü   Supports QinQDouble Tag VLAN

ü   Supports port trunking/aggregating function

l  Network management interface

ü   Supports CLI based on RS232 (CONSOLE) management interface

ü   Supports CLI based on Ethernet (EMU) management interface (TELNET)

ü   Supports Simple Network Management Protocol (SNMP, V1 and V2C)

ü   Implements the device alarm and status monitor, port loop configuration, etc

l  Supports one RS232 user channel in point-to-point mode

l  Perfect alarm indication and performance statistic

l  Supports hot-spare power, the power consumption is less than 12W

ü   -48V DC single power access

ü   -48V DC double power access

ü   220V AC single power access

ü   220V AC double power access

ü   -48V DC&220V AC double power access


ZS-P180-(1+1)DUAL FIBER-16E1-4GE-R supports point-to-point, point-to-dual point, ring and chain network application, refer to Figure 3-1, Figure 3-2,Figure 3-3 and Figure 3-4 shows:


In point-to-point mode, the Ethernet transmission bandwidth can be doubled to 2.5G by setting the port-trunking function.




Note: The LA<->LB connection sequence is required for all elements in the Ring or Chain networks
