1.SFP optical module operating temperature range description
Commercial Temperature Range (COM): 0 to 70°C (32158°F) Extended Temperature Range (EXT): -5 to 85°C (23 to 185°F) Industrial Temperature Range (IND): -40 to 85°C (-40 to 185°F) Storage temperature range: -40 to 85°C (-40 to 185°F)
2.What does NEBS 3 ESD mean?
NEBS is the abbreviation of Network Equipment Building System. It is a set of standards for building network equipment that can withstand various environmental pressures. NEBS has three levels: Level 1, Level 2 and Level 3.
Class 1 refers to situations where minimum compatibility with the environment is required; Class 2 is suitable for limited operability of the product; Class 3 (NEBS 3 ESD) certification guarantees the maximum operability of the device, it also certifies that the device will operate under harsh conditions Perform well under extreme environmental conditions without interfering with the rest of the surrounding electronic equipment, NEBS Level 3 certified network equipment is quite important in mission-critical applications.
That is to say, compared with GLC-T or GLC-TE, the SFP-GE-T optical module can withstand greater stress and is less prone to failure.
3.How to choose GLC-T, GLC-TE and SFP-GE-T optical modules?
In fact, the transmission effects achieved by these three optical modules are similar, and any optical module you choose can achieve Gigabit transmission. However, it is worth noting that Cisco GLC-T and SFP-GE-T optical modules will The sales will be terminated on January 1, and will be replaced by GLC-TE optical modules. If the product is directly traded with the telecommunications company (required for NEBS), it is necessary to choose an SFP-GE-T optical module with NEBS 3 ESD function.
