H3C SFP-XG-LX-SM1270-BIDI Optical Module sample report

      H3C has model SFP-XG-LX-SM1270-BIDI optical module products, can be in single-mode fiber to support 10G Ethernet transmission of 10KM, Moduletek Limited Laboratory of the product samples for testing, to facilitate a further understanding of the product's performance indicators and the effect of the actual machine use.
1. Product Introduction
      H3C SFP-XG-LX-SM1270-BIDI optical module supports 10KM link length on 10G standard single-mode fiber (SMF) G.652. The official key parameter information and the physical appearance of the module are as follows:

Table 1 SFP-XG-LX-SM1270-BIDI Optical Module Key Parameter Information

Description:
 ● BIDI optical modules use different center wavelengths in the transmit and receive directions, thus enabling bi-directional transmission of optical signals within the same fiber.
 ● BIDI modules must be used in pairs, for example, if SFP - XG - LX -SM1270- BIDI is used at one end, SFP - XG - LX -SM1330- BIDI must be used at the other end.
