Client side in the telecoms network

In general we can make the distinction between the line side optical backbone (or transport core) and the so-called client side where the service provider is offering connectivity to a CPE (customer premise equipment).

Oftentimes client side is a good place to start when considering the move to a quality compatible because the technical and engineering demands are less rigorous and the value of the services are generally lower and thus the transition can be managed more easily by all concerned. It is also a way to drive a significant cost reduction and is in keeping with observed trends whereby operators nowadays prefer to pick and choose from a range of selected vendors who best meet their needs in terms of price and quality.

TXO Optics is already providing transceivers for 1G, 10G,  40G and 100G  in this specific area to telco customers globally and case studies and references are available on request.

Within this field, bi-directional transceivers are gaining traction because of the obvious commercial advantages of going up and downstream over a simplex fibre using different wavelengths rather than up and down separately over duplex as traditionally. TXO Optics routinely provides these transceivers for new implementations for 1G and 10G services over 10km, 40km and also 80km (including 10G). It also includes the increasingly popular CSFP. This is a compact small form factor pluggable and is in fact a double or dual bidi in the regular package. This was developed specifically for these types of deployments where even greater port /rack density is desirable from an economic perspective.

Testing for compatibility, functionality and that the module can be read electronically by the network management system are all covered in our testing lab before shipment.

Our portfolio for this use case includes Cisco including OLT deployment, Juniper, Huawei, Alcatel, Keymile, Nortel, Siemens and so on. Please contact us to find out more.

Operators with regular deployments know that once their technical team has validated the product it is easy to order the required optics on a just-in-time basis, knowing that the product will be delivered on a short lead time ready for implementation. Many customers also require a custom part code and label which is also all part of the service.

Another good example is so-called “grey interfaces” whereby the telco is connecting customers to a DWDM system by means of a router. Typically this is achieved by means of optical fibre and transceiver connecting the router to the transponder shelf within the DWDM system.
