Gigaopto’s GTS-L13B1-10DC is a high performance module transceiver for long-range data communication and interconnect applications which operate at 25.78Gb/s up to 10km using single mode fiber(SMF) via duplex LC receptacle.

The transmitter section uses a 1310nm multiple quantum well DFB laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC, and featuring with Gigaopto’s proven circuit, this SFP28 LR provides reliable long life, high performance and consistent service.

It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C interface. It has built-in clock and data recovery (CDR).

This SFP28 LR transceiver module is fully compliant with the SFP28 MSA, RoHS, SFF-8424, SFF-8431 and SFF-8432 standards.

Every 25G LR is tested in targeted host devices for superior performance, quality, and reliability before shipping.
