The CT-1250TBP-JB4L-A from Coretek Opto Corp. is the high performance and cost-effective module for
serial optical data communication applications specified for single mode of 1.25 Gb/s. It operates with +3.3V
power supply. The module is intended for single mode fiber, operates at a nominal wavelength of Tx: 1490nm /
Rx: 1310nm and complies with
Multi-Source Agreement (MSA) Small Form Factor Pluggable (SFP)
. 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.
The module is a single fiber connector transceiver designed for use in Gigabit Ethernet applications and to
provide IEEE-802.3ah compliant link for 1.25Gb/s intermediate reach applications. The characteristics are
performed in accordance with Telcordia Specification GR-468-CORE.
E MC
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.
E y e S af e t y
The transceivers have been designed to meet Class 1 eye safety and comply with EN 60825-1.
