自动绕过有缺陷或断开连接的节点
每个端口再生串行光信号
可配置电缆长达10公里的长度
GE Fanuc / VMIC VMIACC-5595 Gb/s反射存储器集线器组件是一个托管集线器，旨在与GE Fanuc / VMIC 5565系列反射存储器实时网络产品一起运行。反射内存集线器可以在检测到信号丢失或有效同步模式丢失时自动绕过端口，从而允许网络中的其他节点保持运行。由于光端口采用SFP (small form factor pluggable)收发器，因此只需要填充所需的端口。VMIACC-5595 SFP光模块可以是多模(短距离)或单模(长距离)光模块的组合。该特性允许在小型网络中节省成本并优化系统。对于较大的网络，几个VMIACC-5595组件可以级联，允许最多256个节点的托管集线器阵列。每个端口再生串行光信号，消除了插入损耗和电缆衰减的问题。信号再生也减少了抖动。RS232端口提供了通过简单的PC串口监控和控制反射存储器网络的能力。以太网端口功能允许用户通过局域网(LAN)或Web浏览器远距离监视和控制集线器

VMIACC-5595可配置为19英寸1U机架式插框或桌面插框。通用电源允许几乎任何国际电源标准的操作。

当检测到没有有效的同步模式时，VMIACC-5595会自动绕过端口。三个led，相邻每个端口，提供端口状态的视觉指示。其他状态指示和操作模式可通过串行端口或以太网端口获得。

状态信息包括已安装收发器的检测、信号(光)的检测、有效同步模式的检测、端口运行速度(2Gb/s)。控制寄存器允许在没有单一有效同步模式或多个同步模式的情况下绕过通道。旁路也可以简单地基于信号(光)的损失。此外，无论状态指示灯如何，每个端口都可以手动强制激活或绕过。

The GE Fanuc / VMIC VMIACC-5595 Gb/s Reflective Memory Hub Assembly is a managed hub designed to operate with the GE Fanuc / VMIC 5565 family of Reflective Memory real-time network products. The Reflective Memory hub can automatically bypass ports when it detects a loss of signal or the loss of valid synchronization patterns, allowing the other nodes in the network to remain operational. Since the optical ports are implemented with small form factor pluggable (SFP) transceivers, only the required ports need to be populated. The VMIACC-5595 SFP transceivers can be a combination of either multimode (short distance) or single-mote (long-distance) transceivers. This feature permits a cost saving in small networks as well as system optimization. For larger networks, several VMIACC-5595 assemblies can be cascaded, permitting a managed hub aray with up to 256 nodes. Each port regenerates the serial optical signal, eliminating the problems with insertion losses and cable attenuation. Signal regeneration also reduces jitter. The RS232 port gives the ability to monitor and control the Reflective Memory network through a simple PC serial port. The Ethernet port feature allows the user to monitor and control the hub from great distances through a local area network (LAN) or via a Web browser

The VMIACC-5595 can be configured as a 19-inch 1U rack-mountable enclosure or as a desktop enclosure. The universal power supply permits operation with nearly any international power standard.

The VMIACC-5595 automatically bypasses ports when the absence of valid synchronization patterns is detected. Three LEDs, adjacent to each port, provide a visual indication of the port status. Additional status indications and modes of operation are available through either the serial port or the Ethernet port.

Status information includes the detection of installed transceivers, the detection of signal (light), the detection of valid synchronization patterns, and the port operation speed (2Gb/s). Control registers allow the channel bypass to be based on the absence of a single valid synchronization pattern or multiple synchronization patterns. A bypass can also be based simply on the loss of a signal (light). In addition, each port can be manually forced either active or bypassed regardless of the status indicators.
