Description
Overview
GAOTek Data Center Transceiver is intended for 10 km (6.21 mi) reach service from 24.33 Gb/s to 28.05 Gb/s DWDM D18 to D61 single mode high-speed communications equipment where low-cost, extraordinary performance and reliability are essential. It consumes low power, operates based on a 3.3 V DC power supply and is offered in the industrial temperature range. They are compliant with SFP28 MSA, SFF-8431 and SFF-8432.
The low jitter and low bit error rate optical assembly features a D18 to D61 EML laser transmitter and PIN receiver. It utilizes internal clock and data recovery (CDR) units on transmitter and the receiver chains for low jitter compliance. The differential AC coupled Tx and Rx data interfaces are CML compatible. The device is a Class I laser safety compliant.
