In booth #384 at the European Conference on Optical Communications (ECOC 2016) in Düsseldorf, Germany (19-21 September), Oclaro Inc of San Jose, CA, USA (which provides components, modules and subsystems for optical communications) is featuring a live demonstration of a 400GBASE-LR8 CFP8 transceiver, the firm's CFP2-ACO (analog coherent optical) transceiver, and a full portfolio of 100G components and modules.
"The explosive growth in applications such as video services, smart phones and cloud-based software solutions is driving the need for high network speeds to meet the growing bandwidth demands for data-intensive applications," notes chief commercial officer Adam Carter. "Our ECOC line-up demonstrates our advancement and leadership in speeds of 100G and beyond, integrated small form factors, photonic devices, and indium phosphide (InP) technology, which are delivering the speed, power consumption and size required for these services."
Featuring a small 40mm x 102mm x 9.5mm form factor, the new CFP8 transceiver module delivers four times more bandwidth than existing 100G solutions, enabling Oclaro to meet demand for higher data rates between router and transport 400G client-side interfaces in core networks. The CFP8 leverages Oclaro's proven technology from its earlier CFP, CFP2 and CFP4 designs. This includes its cooled 1310nm 28Gbps EA-DFB (electro-absorption distributed feedback) laser technology, and 28Gbps 4-channel integrated PIN-PD (photodiode) array. Additional features of the CFP8 transceiver include the following:
- compliant with 400GBASE-LR8 optical and CDAIU-16 electrical interface specifications that are under final standardization process by the IEEE 802.3bs task force;
- fully integrated 8l x 53.125Gbit/s optical transceiver module modulated using 4-level pulse amplitude modulation (PAM4) format;
- consists of 1310nm wavelength EA-DFB laser diodes, driver ICs, PIN photodiodes, trans-impedance amplifier (TIA) ICs, optical multiplexer/demultiplexer and a PAM4 to NRZ encoder/decoder and SerDes integrated digital signal processing (DSP) IC with a 16-channel x 26.5625Gbit/s electrical interface;
- conforms to CFP8 hardware specifications for mechanical dimensions, connectors and footprint;
- and features power supply voltage of +3.3V and is hot pluggable in the Z-direction by a 124-pin connector.
Already shipping in thousands of units, Oclaro reckons that its CFP2-ACO represents a milestone in acceptance of the coherent CFP2-ACO form factor. Compared to conventional solutions, the coherent CFP2-ACO module features what is claimed to be an unprecedented small form factor to enable increased density at the faceplate, reduced power dissipation, and optimal optical performance. In addition, the CFP2 pluggable form factor enables users to minimize first installation costs and maintain flexibility to scale networks over time by adding more capacity as needed. As a result, the CFP2-ACO technology enables users to achieve the higher density, lower cost and lower power dissipation needed for next-generation 100G and 200G coherent networks, the firm says.
Also on display is a portfolio of components and pluggable modules showcasing Oclaro's technology for enabling bandwidths at 100Gbs, 200Gbs and 400Gbs. Along with the CFP2-ACO, this includes lithium niobate modulators at 100Gb/s and 400Gb/s as well as a portfolio of μ-ITLAs (micro integrated tunable laser assemblies) supporting bandwidths up to 400Gb/s for long-haul, metropolitan and datacenter interconnect markets. For intra-datacenter and enterprise networks, Oclaro's portfolio of 100Gb/s single-mode pluggable modules (including the CFP, CFP2, CFP4 and QSFP28 form factors along with the 400G CFP8) is also on display.
