Lambdatrail™

Services, Functionality

How many full duplex services can be handled with a single fibre system?
- In the LT-108 a 16+2 lambda filter is used. This results in 8 full duplex services which can be transported over a single fibre.
Is a multiplexer able to transport different services in parallel?
- Yes, each channel can be thought as separate fibre connection which is able to transport its own and independent service.
Which services can I transport with Lambdatrail?
- You can transport any service between 100 Mbps and 10 Gbps fully transparent regarding protocol and speed.
  
  Services of lower speeds (i.e. E1/E3 or standard Ethernet) have to be aggregated by an external multiplexer.
Does Lambdatrail require special SFPs within attached devices?
- No, all needed adaption for distance and WDM colour is done with Lambdatrail itself.
What is the influence of multiple services with different speeds regarding the covered distance?
- If all services run on 1-2 Gbps the published maximum distance of 70 km is appropriate.
  
  If one or multiple services run on 4, 8 or 10 Gbps the max. distance is reduced to 40 km (with 4 Gbps) respectively 10 km (with 8/10 Gbps).
Which delay is added with Lambdatrail?
- The delay added by each Lambdatrail box is 200 pico seconds (at 1-10 Gbps).
What kind of power supplies are available?
- You can choose between 230V AC and 48V DC modules. They can be used in pairs or mixed.
How is cooling done?
- There’s an integrated fan module which accommodates two fans. Per default they are switched on and off by a temperature sensor. The cool air is taken through holes in the front panel and blown out on the back of the device.

Maintenance, Upgrading

Can a Lambdatrail which is not fully equipped with SFPs be upgraded for more services?
- Yes. The extension can be done without service disruption. This work has to be handled by a certified partner.
Can Lambdatrail run with just one power supply?
- The multiplexers are delivered with two power supplies always. They are fully redundant. That means that the mux can run with one PS only if the other one fails. The defective module can be replaced not disrupting the service.

Management

Is there a remote management possibility?
- There’s a separate in band management path (OSC) which is used to monitor the remote device. All locally available values and functionalities are there.
How can specific services be monitored?
- All SFPs in Lambdatrail are equipped with optical diagnostic functionality. Herewith each channel can be monitored.
