10/100/1000M optical fiber switch

FEATURES

•  18 SFP sockets and 4 RJ45 electrical ports (optional)

•  The optical interface supports three types of optical fibers: multi-mode dual-fiber, single-mode dual-fiber, and single-mode single-fiber

•  RJ45 electrical port can adapt to 10/100/1000M,full/half duplex mode

•  RJ45 port supports straight-through or cross-over automatic identification function (AUTO-MDIX)

•  SFP port supports 1000M full duplex mode

•  Provides four-level dipswitch function, supports optical port aggregation, electrical port aggregation, flow control and storm suppression functions

•  Low power consumption (10W), less heat generation and good stability

•  The optical port supports electrical modules and supports hot swapping

Newbridge®  ND-920-18FX4TX-SFP  is  a  self-developed  full  Gigabit   unmanaged   Ethernet  switching product, with 19-inch steel shell standard rack design, providing four 1000/100/10M adaptive 1000Base-T interfaces and 18 1000Base-X Gigabit optical interfaces, and four-level dipswitch function. It supports optical port aggregation, electrical port aggregation, flow control and storm control. Easy to manage and maintain, suitable for campus, hotel and enterprise campus network access application scenarios.

Supports port aggregation to effectively increase link bandwidth, achieve link backup and improve link reliability. Support port monitoring, statistics of each port's traffic information, convenient to monitor traffic and  analyse  network  anomalies.  Support  bandwidth  control,  configure  the  transmission   rate   of  data input/output  of  ports,  and  reasonably  allocate  bandwidth.  Supports  storm  suppression,  limiting  the broadcast traffic allowed to be received by the port to avoid broadcast storms.

It enables seamless connection of Gigabit Ethernet optical and electrical signals. It is small in size and flexible  in  networking.  The  switching  chip  adopts the  latest  integrated  circuits  with  stable  performance, excellent  quality  and  high  cost  performance.  All  ports  support  non-blocking,  full  wire-speed  packet forwarding; the product adopts thickened metal shell, beautiful and sturdy, with an operating temperature of 0°C-+40°C; the product's average trouble-free operating time reaches more than 100 000 hours;
