The 25G SFP28 BIDI 30km fiber transceiver, 1270nm/1330nm, Simplex LC, EML Laser, APD receiver,-40℃ ~ 85℃

Description

Features of SFP28 BIDI

• Supports 24.3Gbps to 26.5Gbps bit rates
• 1270nm DFB Laser and APD receiver for YSP28-B7330
• 1330nm DFB Laser and APD receiver for YSP28-B3730
• Up to 30km on 9/125µmSMF
• Simplex LC receptacle optical interface compliant
• Hot pluggable
• All-metal housing for superior EMI performance
• RoHS6 compliant (lead free)
• Operating case temperature: Commercial: -5ºC to +70°C; Extended: -20ºC to +80°C; Industrial: -40ºC to +85°C

 

Applications

• 5G Remote Access: When deploying 5G base stations in remote areas or across mountainous regions, the distance often exceeds the standard 20km. At this point, the 30km module is a must-have;
• Cost Savings in Fiber: In cases where the cost of renting long-distance fiber optic cables is extremely high, the BIDI technology enables two-way 25G transmission through a single fiber, directly reducing half of the fiber leasing costs;
• Relay Replacement: In certain scenarios, using the 30km module can avoid setting up relay stations in the middle, thereby reducing the overall networking cost.

 

Standards

• Compliant with INF-8431
• Compliant with SFF-8472
• Compatible with IEEE802.3cc
