The high performance 1310nm DFB transmitter coupled with a high sensitivity PIN receiver provide superior performance for applications up to 10km SMF. The fully compliant SFP form factor provides high density applications, hot pluggability, easy optical port upgrades and low EMI emission. The SDH SFP module electrical interface is compliant to XFI electrical specifications. The transmitter input and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled. The module provides differential termination and reduce differential to common mode conversion for quality signal
termination and low EMI.
Cisco offers a range of provide SDH SFP. Products include OC3/ STM-1, OC12/STM-4, and OC48/ STM-16 SFPs for multimode, short reach, intermediate reach, long reach (40km), and long rach (80m) applications.The SFP are compatible with the SDH SFP and ATM standards, and support the digital diagnostic functions specified in the SFF-8742 Multi-Source Agreement (MSA) and the extended operating temperature range from 23 to185°F (-5 to 85°C).
The Eoptolink's Multi-rate Series 2.67Gb/s transceiver module integrates optics and electronics in a Small Form Factor Pluggable SDH SFP 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.
