while the system is include SDH SFP systems in operation.

The Eoptolink's Multi-rate Series 2.67Gb/s transceiver module integrates optics and electronics in a Small Form Factor Pluggable SDH SFP/ SONET package. It is Multisource Agreement (MSA) compatible and designed for operation at 1310 nm and 1550 nm. Although optimized for OC-48/STM-16, it provides multi-rate capabilities and can be used from OC-3/STM-1(155 Mb/s) up to 2.7 Gb/s.The Signamax 065-73FXSM80MG is a Small Form-factor Pluggable (SFP) multimode fiber module that supports Fast Ethernet, SONET OC-3, or SDH SFP over singlemode fiber cable at distances up to 80 kilometers. It adheres to the IEEE 802.3u standard for Fast Ethernet over singlemode fiber at 1550 nm, and is a cost-effective method of providing changeable Fast Ethernet singlemode interfaces to switches and media converters designed for these applications that are equipped with a standard 100Base SFP slot.

 The Integra Networks industry-standard Small Form-Factor Pluggable Interface Converters (SFP) for packet-over SDH SFP, MiRICi-155 optical networking and ATM applications (Figure 1) are hot-swappable optical interfaces that plug into a variety of OEM manufacturers’ router interfaces. MultiRate SFP transceiver provides a fully SONET compliant interface between the SDH SFP photonic layer and the electrical layer. Its microprocessor - based modular design implements all features specified in the SFP MSA compatible 2-wire Serial Digital Diagnostic Monitoring Interface for Optical Transceivers is a network line with transmission speeds of up to 2488.32 Mbit/s (payload: 2405.376 Mbit/s; overhead: 82.944 Mbit/s).
