Gigalight Exhibited Data Center Optical Interconnection Achievements at OFC 2016

Data center optical interconnect technology innovator--Gigalight exhibited the recently-launched low power optical interconnect products at the coming OFC Expo  (booth 2725) in Anaheim Convention Center, California, USA.

(1) Low-power 100 Gb/s QSFP8-SR4 optical transceiver and 100G QSFP28 AOC: its power dissipation of room temperature is only 2W, of 70℃is 2.2W, which compliant with MAX POWER 2.5W standard of SFF-8436 V4.8 MSA Power Level 3.

(2) Low-power 100Gb/s CFP2-SR10 optical transceiver: designed for use in 100Gbps Ethernet and OTN OUT-4 data rate, it adopts 10x 10Gbps parallel fiber channel, has built-in 10 channel VCSEL and PIN array technology, link length of 100m on OM3 and 150m on OM4. Digital diagnostics functions are available via an MDIO interface. It supports network loopback test and software status machine. The max power dissipation in regular temperature is no more than 5.8W, and in total temperature range less than 7W.

(3) Low-power 40Gb/s QSFP+ SR4 GEN2 optical transceiver: the main advantage of this new module compared to the market popular 40G QSFP module is the multi-channel optical power DDM function, which guaranteed the module specification compliance via real-time monitoring compensation. Its power dissipation is only 1.5W.

(4) Low power & cost 25GE SFP28 SR optical transceiver and AOC: this module has DDM TX POWER real-time monitoring function based on COB craft and Gigalight patented optical engine technology. It is designed with the industrial latest CDR, to realize 25GBASE-SR Ethernet compatible and link length up to 100m on OM4. The popular 10Gb/s SFP+ form factor enables it to increase 2.5 times of the bandwidth under the same port density. Its overall consumption is less than 0.7W and single channel sensitivity is -11dBm. 25GE SFP28 and 100G QSFP28 constitute the ecological foundation of next generation data center interchangers.

(5) Low power & cost 40G QSFP PSM LR4(10km) optical transceiver: with COB craft and Gigalight patented optical engine technology, optical coupling efficiency so up to 30% that reduce the module power dissipation. The module is adopted in structure with vertical channel cooling design, in POWER transmitting terminal with new software algorithm, in electric circuit with excellent integrated IC, so that complete software states design. These design advantages ensure module total dissipation is around 2.5W (class 3), four channel eye mask MARGIN is over 30%, and sensitivity better than -14dBm.
