Sync-E TAP

With the introduction of Sync-E, it is of utmost importance to determine whether the clock, which is sent to NodeBs or MSANs, is within the quality requirements in terms of stability. Therefore Sync-E requires wander measurements during commissioning, installation and troubleshooting. In combination with a Wandermeter like the PENDULUM WM-11 the CUBRO Sync-E TAP forms the perfect solution for these challenges and allows direct TIE, MTIE and TDEV clock quality measurements of optical Gigabit lines

Overview

The CUBRO Sync-E TAP extracts the 125MHz Ethernet clock from an optical Gigabit signal. This 125MHz output signal is 100% synchronized to line signal and can be passed to the Pendulum WM-11 Wandermeter (or any other 125MHz Wandermeter) for TIE, MTIE and TDEV analysis and comparison against ITU-T Recommendations.

Clock Outputs

The CUBRO Sync-E TAP features two separate 75 Ohm BNC-f clock outputs. These outputs (A and B) deliver 125MHz signals which are 100% synchronized to the optical Gigabit Ethernet signal. Output A delivers a 125MHz signal which is 100% synchronized to the Gigabit Ethernet Signal from side A while output B delivers a 125MHz signal that is synchronized to the Ethernet signal coming from side B.

Network Link

The CUBRO Sync-E TAP is a fully passive and transparent (data and clock) network device; connected Ethernet traffic is not influenced at all. Thus the original optical Gigabit Ethernet traffic is protected and safe, even if the TAP loses power. Moreover, it features 100% throughput and zero delay.

The network link can be either Multimode (850/1300nm) or Singlemode (1310/1550nm) and features LC Duplex connectors.

Robust Design

The Sync-E TAP is delivered in a rugged cabinet with precise connector labeling and LEDs indicating the link status on the front panel.

Live or Terminated Mode

The CUBRO Sync-E TAP can be used on a live link inserted between two routers or switches. Beside that it can also be used as end equipment terminating the line.

Portable or Rackmount

The CUBRO Sync-E TAP can either be delivered as portable version or as 19“ rackmount version. The 19“ rackmount version is able to hold up to three Sync-E TAPs.

Sync-E TAP Application

The CUBRO SyncE TAP is a fully passive and transparent (data and clock) network device.
Thus, the Ethernet Traffic is not disturbed at all and it also passes through Layer 1 and Layer 2 errors.

Beside the network interfaces for the optical Gigabit Ethernet signal it features two clock outputs.

 

 

 

Clock Outputs Output A delivers a 125MHz signalwhich is 100% synchronized to the Gigabit Ethernet Signal from side A.
Output B delivers a 125MHz signal which is 100% synchronized to the Gigabit Ethernet Signal from side B.

These 125MHz output signals are 100% synchronized to the line signal and can be passed to a 125MHz Wandermeter (like the Pendulum WM-11) for TIE, MTIE and TDEV analysis and comparison against ITU-T Recommendations.
