SFP-OC3-CX

Datasheet Copper OC-3 SFP Transceiver SFP-OC3-CX Features MSA compliance for SFP transceivers (SFF-8472) Detection for Loss-of-Signal (ITU-T G.783) Control for transmit power down* Handles over 12.7 dB of cable loss Extended temperature operation: -20 C to 85 C 75Ω media interface compliance for CMI coded 155 Mbps electrical interfaces - ITU-T G.703 - Telcordia GR-253 Overview MRV’s SFP-OC3-CX module is a Small Form-factor Pluggable (SFP) module that offers easy full-duplex interfacing with 155 Mbps OC-3 electrical interfaces (STM-1e, ES1) over 75Ω telecommunications coaxial cable. It includes Clock and Data Recovery (CDR) in both directions, and a CMI encoder/decoder for transparent NRZ-to-CMI line code conversion. It provides Loss of Signal (LOS) detection for electrical CMI interfaces and the option to disable the transmit driver to support the Link Integrity Notification (LIN) feature on applicable MRV modules. A serial interface provides access to an on-board EEPROM for identification information including manufacturer, part number, serial number, and date code. The SFP-OC3-CS complies with Multi-Source Agreement SFF8472 for SFP transceivers. 75Ω DIN 1.0/2.3 female coaxial interface for Type A and Type D coupling Low power dissipation (0.6 W typical) RoHS 5/6 compliance * LIN support for applicable MRV modules Benefits Provides end user flexibility through independent port configuration Reduces deployment cost for STM-1 electrical interfaces Figure 1: Transceiver Functional Diagram Circuit Pack Interface DATA OUT 155 Mbps TXDIS Applications Typical applications include SDH multiplexer systems or ATMswitch and IP-router equipment supporting SDH physical interfaces. The SFP-OC3-CX module is fully interchangeable with STM-1 and OC-3 optical SFP transceivers, offering system developers an easy migration to STM-1 electrical interfaces. Any system that already supports the STM-1 optical SFP also supports the STM-1 electrical SFP. This modular flexibility minimizes development efforts and time-to-market for STM-1 solutions because a single card design supports both optical and electrical STM-1 interfaces. The SFP-OC3-CX and optical STM-1 SFP interfaces can be changed in the field to match the system port types to the application while the system is in operation. The common SFP interface also allows for reduced inventory of field replacements.
