Juniper compatible EX-SFP-1FE-LX40K Description

Juniper compatible EX-SFP-1FE-LX40K (740-028631) is SFP (Small Form factor Pluggable) Transceiver, operating over Double Fiber Single-Mode Fiber (SMF) optical cable. It has minimum guaranteed optical budget of 25 dB, with in most cases is enough to reach about 40 km distance. However, distance is just indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. EX-SFP-1FE-LX40K (740-028631) compatible transceiver use top quality FP Laser transmitter operating at nominal wavelength 1310 nm. and 1310 nm. PIN Photodiode receiver. It support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Juniper compatible EX-SFP-1FE-LX40K (740-028631) operates in Standard 0°-70°C temperature range and has Double LC interface. SFP support 100-155Mbps data rate and such applications as 100M Ethernet (100Mbps), STM-1 (155Mbps). SFP Double Fiber optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular applications are Enterprice network Fast Ethernet Links, ISP FTTH Networking Fast ethernet Links, SONET/SDH STM-1 Links and other optical links.

EX-SFP-1FE-LX40K (740-028631) Juniper compatible Transceiver is based on our 155M-SFP-40D product, which is fully compliant with SFP Multi Source Agreement (MSA) SFF-8477 standard, product safety standards and is CE/RoHS certified. We perform compatibility tests for EX-SFP-1FE-LX40K (740-028631) Juniper compatible Transceiver with the most recent Juniper networking equipment platforms, allowing us to encode transceiver EEPROM memory to be compatible with and work seamlessly with Juniper platforms!
