Ciena Nortel NTK591SHE7 Compatible 1.25Gbps SFP 1000BASE-CWDM 1590nm 100km SMF Duplex LC DDM/DOM Optical Transceiver Module Ciena Nortel NTK591SHE7 compatible optical transceiver is a dual fiber 1000Mbps Small Form-factor Pluggable SFP CWDM module for use in 1000BASE Ethernet network. SFP CWDM1590-EZX provides 1Gb/s throughput up to 100km over single-mode fiber (SMF) using 1590nm wavelength. This transceiver is fully compliant with SFP Multi-Source Agreement (MSA), IEEE 802.3 1000BASE-CWDM and SERDES standard. Its electrical interface is MSA compliant 20-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex SFP transceiver features highly reliable DFB transmitter and APD photo detector to offer high performance interconnection at 1.25Gbps data rate. Built-in Digital Diagnostic Monitoring/Digital Optical Monitoring (DDM/DOM) support is present for real-time performance monitoring via 2-wire (TWI/I2C) interface. Our modules are factory pre-programmed for compatibility, perform alternatively to genuine Ciena Nortel NTK591SHE7 transceivers.
