Build SFP28 Modules for Data Centers and Radio Access with Industry's First Transceiver IC in Mass Production
Keep heat away from lasers using Maxim Integrated's transceiver chip and TO-can optics.

SAN JOSE, Calif., March 16, 2016 /PRNewswire/ -- Manufacturers of SFP28 modules for data center and radio fronthaul applications can now use TO-cans enabled by the industry's first transceiver IC, which is shipping now from Maxim Integrated Products, Inc. (NASDAQ: MXIM).

Maxim's SFP28 transceiver allows module manufacturers to avoid a driver inside the transmit optical subassembly (TOSA). This keeps heat away from the sensitive laser, simplifies production, and improves yield. Maxim's SFP28 transceiver also includes advanced digital eye tuning capabilities that enable use of low-cost TO-can based optics. The SFP28 module can simply be designed in the same way as an SFP+ module using TO optics, one transceiver IC, and one controller IC.

SFP28 optical modules for data centers and radio fronthaul applications need to offer cost competitive performance relative to the incumbent SFP+ module, while still having low power and a wide operating temperature range. Optimized specifically for these requirements, Maxim's 28.1Gbps low-power transceiver IC has a CDR and laser driver in the transmit path, and a high sensitivity limiting amp and CDR in the receive path.

Maxim will demonstrate its industry-leading SFP28 transceiver and other optical ICs at OFC 2016, March 22-24, in Hall A, Booth 1272,

Key Advantages

  • Enables low-cost optics: Reduced module BOM through the use of TO-can based optics
  • Accelerates time to market: Digital eye tuning at the output reduces design spins
  • Reduces production costs: Reusing TO-can-based 10Gbps manufacturing flow improves yield


  • "Maxim's SFP28 transceiver builds on our proven 100Gbps technology and gives the industry what it needs to move to higher bandwidth interconnect," said Andrew Sharratt, Director of Business Management at Maxim Integrated. "Shipping now to customers who are already in mass production, Maxim's SFP28 IC enables cost effective upgrades to enterprise, hyperscale data center, and radio access networks."
  • "Demand for SFP28 modules will experience strong growth over the next five years, as the market moves from 10Gbps per lane to 25Gbps," said Dale Murray, Principal Analyst at LightCounting Market Research. "With its new transceiver IC, Maxim is poised to support this move by simplifying module design and lowering costs."
