Link Extension

With microWDM™ optical Link Extension solutions no site is too far away!

BTI’s 4th generation of ultra-compact EDFA amplifiers pack the latest optical amplification technology and rich feature set for long reach optical transport. Together with a wide family of chromatic dispersion compensation modules (DCM) and Enhanced Forward Error Correction (EFEC) BTI solutions can deliver up to 180km point-to-point links and up to 600km of unrepeated optical transport with the uses of cascading line amplifiers.

Capabilities

1. The right amplifier for each application: Six different amplifier types allow the network designer to fit the optical reach solution to the right budget and application. Low cost sub-band amplifiers can be used for low DWDM channel count system from single channel up to 16 wavelengths while full band amplifiers will deliver high performance amplification for up to 40 channels systems over multiple spans.
2. Flexible Dispersion Compensation:  Two technologies choices are available to deliver passive chromatic dispersion compensation for long links.  Channelized Fiber-Bragg-Grating (FGB) based DCMs deliver low insertion loss and low cost solutions for any number of channels in the 100GHz ITU-T grid. Dispersion Compensation Fiber Based (DCF) offer flexible chromatic dispersion over the full C-band for any ITU-T grid.
3. Out-of-band Management: Remote optical amplifier locations can be easily managed via in-band management with GCC or with a flexible Optical Supervisory Channel solution. Low cost Pluggable SFPs Optics are used to establish a 100FX Ethernet management channel over the same optical fiber used for transmission.
4. Multiple OADM options: 1, 2 or 4 wavelengths out of the any 40 wavelengths on BTI’s wavelength plan can be optically added or dropped at any intermediate site without incurring in costly Electro-Optical regeneration.

BTI Value

By minimizing the need for Electrical Regeneration in middle sites simpler operation   and lower networks cost are leveraged. Adding an additional wavelength to a long link requires only intervention at the ingress and egress point in the link.
