Description The CT-2500VBP-NB5L-D from Coretek Opto Corp. is a high performance and cost-effective module for serial optical data communication applications specified for multi-rate from 50 Mb/s to 3 Gb/s. It operates with a +3.3 V power supply. The module is intended for single mode fiber, operates at a nominal wavelength of Tx: 1310 nm / Rx: 1550 nm and complies with Multi-Source Agreement (MSA) Small Form Factor Pluggable (SFP). Each module has integrated digital diagnostics functions via an I2C serial interface. The module is a single fiber connector transceiver designed for robust performance in the presence of SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M and SMPTE 424M serial rates including SD-SDI compliant link at 270 Mb/s, HD-SDI compliant link at 1.485 Gb/s and 3G-SDI compliant link at 2.97 Gb/s. It provides extensive operational status monitoring through I2C interface. For the transceiver, output optical power, bias current, RX power, supply voltage and operating temperature are monitored. If a parameter monitored is outside the pre-defined range, the alarm flag associated with the parameter will be raised. 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.
