A network TAP (Test Access Point), optical or electrical, is the first device to provide network visibility. It is vital that this device is highly reliable. It is a hardware device, which can passively capture traffic on a network. It is commonly used to monitor the network traffic between two points in the network. The TAP is normally placed between any two network devices, such as switches, routers, or firewalls to provide network and security personnel with a connection for monitoring devices. TAPs are used for troubleshooting and offer continuous, non- disruptive network access. Cubro provides the best quality for an affordable price. Cubro TAPs are resilient even in the event of a hardware failure. They are engineered to allow traffic to continue passing through them even if the TAP itself stops functioning. Cubro TAPs do not introduce delay or alter the content.
Advantages of Cubro TAPs:

The Cubro Optical TAPs maintain a permanent passive connection for monitoring purposes without introducing a potential point of failure or disturbing other network connections. Cubro passive optical TAPs deliver full-duplex monitoring with zero impact on the network. These TAPs provide a simple but powerful way to conduct in-service monitoring of high-speed optical networks such as SDH/SONET/OTN and Ethernet up to 100 Gbit. Our optical TAPs are completely traffic transparent and offer 100% throughput. Therefore, Cubro optical TAPs can be used for any optical network application, regardless of the bitrate. Whether the task is monitoring of STM-64, STM-256, 10G Ethernet or OTN signals, Cubro is the right choice. The network links can either be multimode (850/1300nm) or single-mode (1310/1550nm). The TAPs can be used for short-haul as well as long-haul applications. Cubro Optical TAPs are delivered with LC type connectors on the input and MTP/MPO on the output. Depending on the available optical power budget, the SM optical splitting ratio is selectable in 10% steps (SM standard is 80/20%), while the MM splitting ratio is always 50/50%. Every splitter used inside the optical TAP is handled carefully and insertion loss is measured before the TAP is shipped to the customer. Highlights
The challenge of tapping a 40 Gbit /100 Gbit multimode link based on a QSFP connector is that the QSFP is defined as a quad channel interface (Q - quad) which means we have 4 x 10 Gbit. These 4 x 10 Gbit are in a kind of trunk, which means that an Ethernet packet is split into 4 chunks and sent in parallel over the 4-fibre links. A special layer 1 protocol ensures that the receiver knows which fibre is which, so that the receivers can reassemble the packet correctly. The Cubro MTO/MTP TAP is connected over MTP connectors (8 fibres) with the QSFP, and the output is also MTP which is connected to the input of the Packetmaster EX484-3. The special features within the Packetmaster EX484-3 help to reassemble the QSFP traffic. Highlights

Cubro Optical BIDI TAP |

Typical fibre connectivity requires dual-strand fibre for two endpoints of the optical full-duplex network, with; the first one used for transmission and the second for reception. However, this can be optimized by using single strand fibre optical transceivers that enable bi-directional full-duplex operation of transmit and receive signals over a single strand fibre by using separate wavelengths - e.g. 1310nm/1490nm or 1310/1550nm. While BIDI transmission systems save fibres they make monitoring data traffic more difficult. How do we distinguish between TX and RX direction? The Cubro optical BIDI TAP is the right solution to this challenge. It passes the BIDI traffic through with full transparency while featuring two independent monitoring outputs – one for each direction. Thus, it allows capturing, decoding and troubleshooting in both directions. Broadband Design The network section of the Cubro optical BIDI TAP is broadband. That means it covers every wavelength between 1290 and 1610nm. Therefore, it can be used for different TX and RX wavelength combinations such as 1310nm/1490nm, 1310nm/1550nm or 1490nm/1550nm Highlights

The major advantage of this concept is easy expansion and installation. Consider a situation where there are 21 single TAPs deployed. In this case, 42 power cords would be required and such a large number of power cords can easily lead to a tangled mess. Compared to other solutions with separate TAPs, the new FlexTAP has only two power connectors for 21 TAPs. The flexible and easy to install solution consists of 4 parts:

The advanced Cubro 10/100/1000 Copper TAP is an all-new development based on the latest PHY chips. This TAP is also a converter TAP because the output ports are SFP, so the user can select the desired media by changing the SFP. There are some special PoE powered and PoE transparent add-ons available as well. Highlights

The EX Aggregator is an intelligent TAP for network data packets featuring high port density, diverse operation modes, flexible deployment and easy management and maintenance. With its excellent adaptability to various network environments it can provide telecommunication data for IDS, network protocol analysers and signalling analysers in real-time as needed. Gbit copper interfaces are still very common in many places, from data centres to enterprise networks. Copper Gbit links are very complicated to tap. Because of the design of these links, tapping them passively has not been possible so far. In case of a power loss situation in the TAP the live link is always interrupted. This interruption time is most critical for networks. Losing a packet is not the biggest issue, however, the link's down status can activate protection mechanism in the network and lead to massive network problems. Highlights
