GAOTek’s SFP+ Tunable Transceiver is an integrated fiber optic transceiver for high speed serial link at defined signalling rates to support different applications for sale to the United States, Canada and Globally. It complies with 10 Gigabit Enhanced Small Form-Factor Pluggable (SFP+) MSA SFF-8431, SFF-8432, SFF-8690 and SFF-8472.



Tunable transceivers have the capability to adjust wavelength. This is achieved by using tunable laser which can be tuned over multiple wavelengths. GAOTek’s tunable SFP+ transceiver covers distances of up to 80 km.


Our 10 Gigabit SFP+ Tunable Transceiver is used with single mode optical fiber and complies with the 10 Gigabit SFP+ MSA. On the transmitter side it has a C-band-tunable integrated Mach-Zehnder (MZ) laser connected using an industry standard LC (Lucent Connector) type optical interface. On the receiver side, the 10 Gbps data stream is received by an APD trans-impedance amplifier, and passed to an output driver. It also features a digital diagnostic monitoring interface for real time information on device operating parameters.

This hot pluggable transceiver complies with the ITU-T G.698.1 standard, and allows:

  •         50 GHz channel spacing for SONET/SDH, IEEE DWDM 10GBASE-ZR for 80 km reach Ethernet applications
  •          DWDM 10GFC for Fiber Channel applications

SFP+ Tunable Transceivers are widely used in WAN, LAN, SAN, Ethernet switches and FC switches and applications. Our SFP+ Tunable Transceiver is ideal for use in the following applications:

  1.          DWDM SONET OC-192 and SDH STM-64
  2.          DWDM 80 km 10G Fiber Channel
  3.          DWDM 10GBASE-ZR/ZW 10G Ethernet
