1.25G BIDI Gigabit SFP Best Optical Transceiver

  • High Performance – Single mode duplex 1.25 Gigabit SFP transceiver, supports up to 20km fiber length connection and 0~70ºC operating temperature.
  • Widely Compatible – The SFP transceiver are widely compatible with Cisco products(Cisco 3000 &6000 series router are not supported) and Netgear, MikroTik, Ubiquity, DLink etc., ( Not recommended for HP, Juniper and Aruba products). The fiber module also works well with switch, router, media converter and more gigabit SFP optic ports
  • High Quality – The shell adopts high density and heat-resistant insulation zinc alloy, high performance chipset, which makes the product more stable and efficient transmission, and low power consumption. More than 1000k+ pcs SFP are already deploy in global market
  • 100% Aging Testing – The gold finger of SFP module are carefully examined to reach the perfect combination of circuit assembly precision. All SFP are 100% aging testing after assembling to ensure that all sold modules are stable and high reliability
  • Fast & Convenient Connection – The SFP support hot swappable, which just need plug and play for fast connection with LC-LC Single-mode fiber path.
