Oclaro unveils first I-temp tunable SFP+ and starts volume production of I-temp SFP28 LR
Oclaro Inc of San Jose, CA, USA (which provides components, modules and subsystems for optical communications) has launched two industrial temperature (I-temp) transceivers designed to drive the market transition to 5G wireless fronthaul systems, giving the flexibility to choose either a 10G TSFP+ I-temp that can fit a WDM fronthaul system into a next-generation 5G wireless network or a 25G SFP28 LR I-temp that significantly increases data capacity and offers low power consumption.
“The 5G market is being fueled by the steady increase in data traffic and our goal is to provide our customers with flexible solutions that can get them to market quickly and within their cost requirements,” says Yves LeMaitre, president of Oclaro’s Optical Connectivity business unit. “Our new 10G TSFP+I-temp is ideal for cost-sensitive customers who want to save on fiber and installation fees, while the SFP28 LR I-temp enables carriers to significantly increase bandwidth,” he adds.
The 10G TSFP+ is Oclaro's latest product to include I-temp and follows its 10G TSFP+ C-temp and E-temp (which are both shipping currently). The TSFP+ is vertically integrated through the use of Oclaro’s in-house ILMZ (integrated laser Mach-Zehnder) chip and its custom-designed transmitter optical sub-assembly (TOSA) and TSFP+ technology. Oclaro achieved 85°C operation by optimizing the operation temperature of the ILMZ chip and it achieved -40°C operation by developing the thermoelectric cooler (TEC) to lower power consumption. The firm also improved the power dissipation of key components and driving conditions of the TSFP+ I-temp to enable wide temperature operation between -40° to 85°C.
Oclaro expects to begin sampling the 10G TSFP+ I-temp in April, with volume production anticipated in third-quarter 2017.
In volume production now, the SFP28 LR I-temp transceiver is designed for enterprise switches, next-generation 5G mobile fronthaul networks, data-center switches and access applications where data rates are increasing from 10Gb/s to 25Gb/s and 40Gb/s to 100Gb/s. The SFP28 LR I-temp leverages Oclaro’s 1310nm 28Gb/s directly modulated laser (DML) chip. The firm also developed a 28Gb/s TO-CAN TOSA for this product using its existing and proven 10G TOSA packaging technology. The SFP28 LR I-temp leverages Oclaro’s in-house 25G DML laser chip operating up to 120°C to eliminate the need for a TEC and provides low power consumption of 1.0W maximum based on excellent slop efficiency, which is critical for wireless systems.
