10G BIDI SFP+ Single Fiber Transceiver 1270/1330nm 20km, DDM, DFB Laser, PIN Photo-detector, Simplex LC Optical Interface

Description

SFP-10G-BX20 Features

• Up to 10.6Gbps data links
• 1270nm DFB Laser and PIN photo-detector for SFP-10G-BX2073
• 1330nm DFB Laser and PIN photo-detector for SFP-10G-BX2037
• Up to 20kmon 9/125µm SMF
• Simplex LC receptacle optical interface compliant
• Hot pluggable
• All-metal housing for superior EMI performance
• RoHS6 compliant (lead free)
• Operating case temperature:

1. Commercial: -5ºC to +70°C
2. Extended: -20ºC to +80°C
3. Industrial: -40ºC to +85°C

Applications

• 10GBASE-LR/LW 10G Ethernet
• 10G Fibre Channel
• 10G SONET
• When the fiber optic pipeline is full and new fibers cannot be laid, but the network needs to be upgraded to 10G bandwidth or connected to nodes within 20km, a single backup fiber optic cable can be used for bidirectional transmission.
• Connect aggregation layer and access layer nodes within a coverage range of 20km, replace dual fiber transmission with single fiber transmission, and improve fiber core utilization.
• Connecting data centers or campus buildings that are 20km apart, replacing more expensive long-distance solutions.

BIDI Transceiver 20km Standards

• Compliant with SFP+ MSA
• Compliant with SFF-8472
• Compatible with IEEE802.3ae
