Juniper compatible SFP-1GE-SX Description

Juniper compatible SFP-1GE-SX (740-031851) is SFP (Small Form factor Pluggable) Transceiver, operating over Double Fiber Multi-Mode Fiber (MMF) optical cable. It has minimum guaranteed optical budget of 7.5 dB, with in most cases is enough to reach about 550 m 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. SFP-1GE-SX (740-031851) compatible transceiver use top quality VSCEL Laser transmitter operating at nominal wavelength 850 nm. and 850 nm. PIN Photodiode receiver. It support DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. Juniper compatible SFP-1GE-SX (740-031851) operates in Standard 0°-70°C temperature range and has Double LC interface. SFP support 1.063-1.25Gbps data rate and such applications as Gigabit Ethernet (1.25 Gbps), 1G Fiber Channel (1.0625 Gbps). SFP Double Fiber optical transceiver is multi-purpose module used in number of different places of today’s networking. Consequently, most popular applications are Internet Service Provider (ISP) Gigabit Ethernet communication links, Enterprice LAN & SAN Networks, Data Center LAN & SAN Networks and other optical links.

SFP-1GE-SX (740-031851) Juniper compatible Transceiver is based on our 1.25G-SFP-550D 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 SFP-1GE-SX (740-031851) 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!
