The EOLP-1696-X-X series single mode transceiver is small form factor pluggable module for bi-directional serial optical data communications such as IEEE 802.3ae 10GBASE-LR/LW/ER. It is with the SFP 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. This module is designed for single mode fiber and operates at a nominal wavelength of CWDM wavelength. There are 18 center wavelengths available from 1270 nm to 1610 nm, with each step 20 nm. A guaranteed minimum optical link budget of 14 dB is offered. The transmitter section uses a CWDM multiple quantum well DFB/EML laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.

CWDM SFP+ LR, CWDM SFP+ ER Ordering information:

Network operators can choose to deploy Coarse Wavelength Division Multiplexing (CWDM) for very low cost and small- to medium-sized scalability, or Dense WDM (DWDM) for reasonable, pay-as-you-grow investment and tremendous capacity. Both technologies are functionally similar. The primary difference is that CWDM uses a wider spacing between wavelengths (20 nm) than does DWDM (1.6 nm and less). Consequently, CWDM supports fewer channels (typically 8-16) than does DWDM (up to 80). Hybrid CWDM/DWDM systems are available in the marketplace and provide an optimum balance, combining CWDM’s low cost of entry with DWDM’s in-service scalability
