80km QSFP28 100G Bidirectional Fiber Transceiver, Side A: Tx1270/Tx1310nm, Side B: Tx1310/Tx1270nm,

Description

Features of Bidirectional Fiber Transceiver

• Up to 80km reach for G.652 SMF
• Cooled 4x25Gb/s LAN WDM Blue or Red Side TOSA, LAN WDM Red or Blue Side ROSA
• 4x25G Electrical Interface
• Single +3.3V power supply
• DDM function implemented
• 2 Wire Serial Interface for module management
• Maximum power dissipation<5.5W
• Operating temperature range: 0℃ ~ 70℃
• Compliant with RoHS6

 

Application

• Long-distance fiber leasing: When the cross-city fiber leased by you has only one core and the monthly rent is extremely high, exchanging this expensive module for a 50% reduction in fiber rent is very cost-effective.
• Metropolitan area network backbone interconnection: Used for direct connection of core network nodes within 80 kilometers.
