Core Product Features
- Universal GBIC form factor gigabit optical transceiver, compatible with legacy D-Link switches equipped with GBIC slots, supporting both multi-mode and single-mode fiber deployment.
- Adopts 1310nm low-loss DFB laser, SC duplex dual-fiber interface; supports 550m transmission over multi-mode fiber and 10km transmission over standard single-mode fiber.
- Hot-swappable plug-and-play design, no power-off required for installation or replacement of host switches.
- Compliant with IEEE 802.3 1000BASE-LX standard, low power consumption, wide industrial temperature range, stable 24/7 non-stop operation.
- Metal shielding housing with strong anti-electromagnetic interference, full RoHS & CE certified Class 1 eye-safe laser module, flexible solution for mixed fiber network renovation.
Typical Application Scenarios
- Hybrid fiber network interconnection: short-distance indoor multi-mode rack uplink and medium-distance cross-building single-mode interconnection within 10km.
- Upgrade of old enterprise/campus GBIC-slot switches, unified optical module deployment for mixed MMF & SMF wiring environments.
- Small branch office private line, medium-range security monitoring backbone transmission.
- Not applicable for ultra-long single-mode transmission, SFP/XFP new-generation slots, and 10G high-speed networking.
