Description
The CT-1225TGT-IH5V-D from Coretek Opto Corp. is the high performance and cost-effective module
for serial optical telecommunication applications specified for single mode of TX 1244Mb/s / RX 2488Mb/s. It
operates with +3.3V power supply. The module is intended for single mode fiber, operates at a nominal
wavelength of Tx: 1310nm / Rx: 1490nm and complies with Multi-Source Agreement (MSA) Small Form
Factor (SFF) 2x10 footprint. Each module consists of a bi-directional optical subassembly that combines a
transmitter with a receiver and an electrical subassembly. All of them are housed in a metal package and the
combination produces a reliable component.Each module is integrated digital diagnostics functions via an I2C
serial interface.
The module is a single fiber connector transceiver designed for use in Gigabit-capable Passive Optical
Network (GPON) ONU applications. The transmitter is operating at burst mode and the receiver is operating at
continuous mode. The characteristics are performed in accordance with Telcordia Specification
GR-468-CORE.
EMC
Most equipment utilizing high-speed transceivers will be required to meet the following requirements:
1) FCC in the United States
2) CENELEC EN55022 (CISPR 22) in Europe
To assist the customer in managing the overall equipment EMC performance, the transceivers have been
designed to satisfy FCC class B limits and provide good immunity to radio-frequency electromagnetic fields.
Eye Safety
This laser based single mode transceiver is a CLASS 1 LASER PRODUCT, Hazard level 1. It complies
with IEC 60825-1 Ed.2: 2007-03 and FDA performance standards for laser products (21 CFR 1040.10 and
1040.11) except for deviations pursuant to Laser Notice 50, dated June 24, 2007.

Enhanced Digital Diagnostic Interface
The memory map in the following describes an extension to the memory map defined in SFF-8472MSA.
The enhanced interface uses the two wire serial bus address 1010001X (A2h) to provide diagnostic information about
the module’s present operating conditions. The transceiver generates this diagnostic data by digitization of internal
analog signals. Calibration and alarm/warning threshold data is written during device manufacture.
